What is a normal 17-OH progesterone level for females?

Normal 17-OH progesterone in females depends on menstrual cycle phase. Follicular phase (days 1–12): approximately 15–70 ng/dL (0.5–2.1 nmol/L). Luteal phase (days 13–28): approximately 35–290 ng/dL (1.0–8.7 nmol/L). Postmenopausal: typically below 51–70 ng/dL. Always use the reference interval on your specific lab report — values differ between laboratories and test methods.

What does low 17-hydroxyprogesterone in females mean?

Low 17-OHP in females is most commonly a normal finding. In the early follicular phase levels are physiologically at their lowest. Women on combined oral contraceptives typically have suppressed 17-OHP. Low levels without symptoms of adrenal insufficiency do not require clinical action. If low 17-OHP accompanies fatigue, low blood pressure, or salt craving, cortisol and ACTH are the more appropriate tests to evaluate adrenal function.

What is the normal range for 17-OH progesterone in ng/mL and nmol/L?

To convert ng/dL to ng/mL, divide by 100: follicular 15–70 ng/dL = 0.15–0.70 ng/mL; luteal 35–290 ng/dL = 0.35–2.90 ng/mL. To convert to nmol/L, multiply ng/dL by 0.0303: follicular 15–70 ng/dL ≈ 0.5–2.1 nmol/L; luteal 35–290 ng/dL ≈ 1.0–8.7 nmol/L.

What does high 17-OH progesterone mean in females?

High 17-OHP in females most commonly reflects non-classic CAH due to 21-hydroxylase deficiency, or mildly elevated levels from PCOS. A luteal-phase result can also appear elevated when compared against a general or follicular-phase range. Persistent follicular-phase elevation with androgen-excess symptoms warrants an ACTH stimulation test to evaluate for non-classic CAH.

What is the 17-OH progesterone LCMS normal range female?

For adult women tested by LC/MS-MS: follicular phase approximately 15–70 ng/dL (0.5–2.1 nmol/L); luteal phase approximately 35–290 ng/dL (1.0–8.7 nmol/L). LC/MS-MS ranges should not be compared against immunoassay ranges — the methods have different reference intervals. LabCorp test 500540 is their LC/MS-MS method.

What does elevated 17-OHP mean for PCOS?

In PCOS, 17-OHP may be mildly elevated from ovarian androgen production. The key question is whether the elevation represents non-classic CAH, which can present identically to PCOS. An ACTH stimulation test differentiates them: non-classic CAH typically produces a stimulated 17-OHP above approximately 1,500 ng/dL; PCOS typically produces only a mild increase below this threshold.

What does a high 17-OHP in a newborn mean?

High 17-OHP on newborn screening suggests possible classic CAH, which can cause life-threatening salt wasting if untreated. Many positives in premature or sick newborns are false positives — confirmatory serum testing, electrolytes, and clinical evaluation are required before diagnosis. A positive screen warrants prompt paediatric evaluation.

What is an ACTH stimulation test for 17-OHP?

The ACTH stimulation test measures 17-OHP at baseline and 60 minutes after synthetic ACTH injection. A stimulated level above approximately 1,500 ng/dL strongly suggests non-classic CAH. It is the gold standard for confirming non-classic CAH and distinguishing it from PCOS.

What does 17-OH Progesteron mean in German?

17-OH Progesteron (also 17-OH-Progesteron or Progesteron 17-OH) is the German term for 17-hydroxyprogesterone. German labs report in ng/dL or nmol/L: Follikelphase ~15–70 ng/dL (0.5–2.1 nmol/L); Lutealphase ~35–290 ng/dL (1.0–8.7 nmol/L). Erhöht = elevated; erniedrigt = low. Note cycle phase at collection when interpreting elevated results.

Why would 17-OH progesterone be low during the follicular phase?

Low 17-OHP in the follicular phase is usually physiologically normal — it is the lowest point in the cycle. Women on combined hormonal contraceptives have suppressed 17-OHP throughout the cycle. Women being treated for CAH with glucocorticoids have intentionally suppressed 17-OHP as a treatment goal. Low follicular-phase 17-OHP without symptoms is generally not clinically actionable.

Lab Results Explained and Tracked

AT A GLANCE

17-OH progesterone (17-OHP) is produced by the adrenal glands and ovaries; it is an intermediate in the cortisol synthesis pathway
Normal range in females depends on menstrual cycle phase — follicular phase (days 1–12): ~15–70 ng/dL (0.5–2.1 nmol/L); luteal phase (days 13–28): ~35–290 ng/dL (1.0–8.7 nmol/L)
A result that looks elevated may be normal if collected in the luteal phase — always check which phase-specific range applies to your result
Low 17-OHP in the early follicular phase is physiologically normal and rarely clinically significant
17-OHP is not the same as progesterone — they are different hormones; the tests are not interchangeable
LC/MS-MS is a more specific test method than immunoassay; reference ranges differ between methods — do not compare results across methods
High 17-OHP with androgen-excess symptoms most commonly indicates non-classic CAH or PCOS
Normal ranges vary by lab, age, sex, and test method. Results can also vary significantly depending on time of day, cycle phase, medications, and assay method. Always use the reference range on your specific lab report.

NORMAL 17-OH PROGESTERONE LEVELS IN FEMALES

Population	ng/dL	nmol/L	Notes
Adult females — follicular (days 1–12)	15–70	0.5–2.1	Best phase for baseline testing
Adult females — luteal (days 13–28)	35–290	1.0–8.7	Physiologically elevated; not abnormal
Adult females — postmenopausal	< 51–70	< 1.5–2.1	Lab-dependent
Adult males	< 220	< 6.6	Less phase-dependent
Prepubertal children	< 100	< 3.0	Method-dependent
Newborns, first 24 hrs	~1,000–3,000	~30–90	Falls rapidly; basis for CAH screen
Newborns, >24–72 hrs	< 100–200	< 3–6	Lab-specific cutoffs

Unit conversions:

ng/dL → nmol/L: multiply by 0.0303
nmol/L → ng/dL: multiply by 33.0
ng/dL → ng/mL: divide by 100 (so 70 ng/dL = 0.70 ng/mL)

All ranges are illustrative. Reference intervals differ between laboratories and assay methods. Always use the range printed on your lab report.

If your result says "< 50 ng/dL" or "< 20 ng/dL": This is a reporting threshold, not a dangerously low value. For women in the follicular phase, a result below 50 ng/dL is within or below the normal range — a reassuring finding, not a cause for concern.

If your result appears "high" but your blood was drawn after ovulation (luteal phase): A luteal-phase result of up to 290 ng/dL is entirely normal. A result that looks elevated may simply reflect the expected post-ovulation rise. Always confirm which cycle phase applies to your reference range before drawing conclusions.

WHAT LEVEL OF 17-OHP IS CONCERNING?

Result (ng/dL)	Typical interpretation
< 50, early follicular phase	Normal — reporting threshold, not a low value
15–70, follicular phase	Normal follicular range
35–290, luteal phase	Normal luteal range — not elevated
> 70 follicular / > 290 luteal	Above phase-specific range — recheck cycle phase; repeat if needed
200–1,000, follicular phase	Mildly-moderately elevated — consider ACTH stimulation test to evaluate for non-classic CAH
> 1,000, adults	Significant elevation — warrants endocrinology evaluation
> 2,000, newborns/infants	Strong concern for classic CAH — requires prompt clinical evaluation

Thresholds are illustrative — always use the reference range on your specific lab report and interpret alongside clinical context.

17-OH PROGESTERONE LEVELS BY MENSTRUAL CYCLE PHASE

17-OHP follows the ovarian cycle in premenopausal women. The corpus luteum — the temporary structure that forms after ovulation — produces 17-OHP alongside progesterone, causing levels to rise through the luteal phase. This is normal and expected.

Why this matters for your result: A result of 200 ng/dL collected on day 21 of your cycle (luteal phase) is within the upper normal range. The same value collected on day 3 (early follicular phase) is above the follicular-phase upper limit and warrants clinical evaluation. Both are the same number — the interpretation changes entirely based on cycle day.

Best collection conditions for an interpretable baseline:

Days 2–5 of the menstrual cycle (early follicular phase)
Early morning (8–10 AM) — adrenal hormones are at daily peak
Before starting steroid medications or hormonal contraceptives if clinically feasible

IS 17-OH PROGESTERONE THE SAME AS PROGESTERONE?

No. They are structurally related but functionally different hormones, and the tests are not interchangeable.

	Progesterone	17-OH Progesterone (17-OHP)
Primary source	Ovaries (corpus luteum)	Adrenal glands + ovaries
Main function	Prepares uterine lining; supports pregnancy	Intermediate in cortisol synthesis
Rises in luteal phase	Yes	Yes
Tested for	Ovarian function, pregnancy	CAH, androgen excess, adrenal function
High result indicates	Ovulatory issues, luteal phase problems	CAH, enzyme defect, androgen excess

If your lab report says "Progesterone" and you were expecting "17-OH Progesterone" — or vice versa — those are different tests. Check the full test name on your report before comparing results or reference ranges.

LOW 17-OH PROGESTERONE IN FEMALES

Low 17-OHP in females is among the most common search-driven concerns for this biomarker — and it is usually normal.

What is considered low? Below the lower end of the follicular-phase reference range for your lab — often below 15 ng/dL (0.5 nmol/L), though lab-specific floors vary. Many labs report low results as "< 50 ng/dL," "< 20 ng/dL," or a similar threshold.

What does "17-hydroxyprogesterone less than 50" mean? A result reported as "< 50 ng/dL" means the measured level is below 50 ng/dL — the detection floor or reporting threshold of the assay. It does not mean the level is zero or that something is wrong. For adult women in the follicular phase, the reference range typically begins at 15–20 ng/dL, so a result below 50 is normal. There is no clinical action required for this result in isolation.

Common reasons for low or low-normal 17-OHP in females:

Early follicular phase (days 1–5) — physiologically lowest point in the cycle; normal
Combined hormonal contraceptives — suppress ovarian and adrenal androgen production; low 17-OHP is expected
Glucocorticoid therapy — hydrocortisone, prednisone, dexamethasone all suppress ACTH and lower 17-OHP; this is the treatment goal in managed CAH
Postmenopause — ovarian 17-OHP production declines; lower values are expected
Normal variation — many women have low-normal levels throughout the cycle without any underlying condition

When is low 17-OHP clinically relevant? Only in the context of suspected adrenal insufficiency — and even then, cortisol and ACTH are the more appropriate primary markers. Fatigue, low blood pressure, salt craving, and weight loss alongside a low 17-OHP should prompt cortisol/ACTH evaluation.

WHAT IS 17-OH PROGESTERONE?

17-OHP (17-hydroxyprogesterone, 17α-hydroxyprogesterone) is produced primarily by the adrenal glands and, in premenopausal women, also by the ovaries. It sits in the middle of the cortisol synthesis pathway — made from progesterone, converted by the enzyme 21-hydroxylase into 11-deoxycortisol, then into cortisol.

When blocked: If 21-hydroxylase is deficient (the cause of congenital adrenal hyperplasia), 17-OHP cannot be efficiently converted. It accumulates. The pituitary releases more ACTH, driving further 17-OHP buildup and diversion of excess precursors into androgens — explaining the androgen-excess symptoms that accompany CAH.

HIGH 17-OH PROGESTERONE IN FEMALES

Most common causes:

Non-classic CAH (21-hydroxylase deficiency) — the most important cause of persistent adult-onset elevation. Baseline 17-OHP typically 200–1,000+ ng/dL; confirmed by ACTH stimulation (stimulated value above ~1,500 ng/dL)
PCOS — may cause mild elevation from increased ovarian androgen production; typically produces only mild ACTH-stimulated increases compared with non-classic CAH
Luteal-phase collection — result interpreted against follicular-phase range; not a pathological elevation
Classic CAH in an undiagnosed older child or adult — markedly elevated, usually with significant androgen-excess symptoms
Adrenal tumour — rare; usually accompanied by additional signs of adrenal hypersecretion

Symptoms associated with high 17-OHP / androgen excess:

Hirsutism (excess body or facial hair)
Acne, particularly jaw and back acne
Irregular or absent periods
Infertility
Early pubic or underarm hair in children (precocious adrenarche)
Rapid growth with early bone maturation in childhood
In female newborns with classic CAH: virilisation of external genitalia at birth

When to investigate further: Persistent elevation in the early follicular phase (above 200 ng/dL) alongside any of the above symptoms warrants an ACTH stimulation test to evaluate for non-classic CAH.

When is high 17-OHP an emergency?

In adults, even marked elevations above 1,000 ng/dL are clinically significant but not typically acute emergencies — they warrant endocrinology evaluation within days to weeks, not hours. In newborns, high 17-OHP indicating classic CAH with salt-wasting is a genuine emergency requiring prompt treatment to prevent a life-threatening electrolyte crisis. An adult with known CAH who develops acute symptoms (severe weakness, vomiting, low blood pressure, confusion) requires emergency evaluation regardless of 17-OHP level.

17-OH PROGESTERONE LC/MS-MS NORMAL RANGE IN FEMALES — AND WHY METHOD MATTERS

Many lab reports include "LCMS" or "LC/MS-MS" in the test name — this refers to liquid chromatography–tandem mass spectrometry.

Why it matters for 17-OHP: Immunoassay can cross-react with structurally similar steroids, producing falsely elevated 17-OHP — especially in newborns and borderline adult cases. LC/MS-MS separates 17-OHP from similar compounds before measuring it, giving a more specific result.

Practical effect: LC/MS-MS reference ranges are generally lower than immunoassay ranges. A borderline elevated immunoassay result may be normal by LC/MS-MS. Do not compare a result from one method against a reference range from the other.

LabCorp test 500540 is their LC/MS-MS method for 17-hydroxyprogesterone. If your report says "17-OH Progesterone LCMS" or includes "LC/MS-MS" in the test name, the reference ranges on that report are specific to that method.

CONGENITAL ADRENAL HYPERPLASIA (CAH)

CAH is a group of inherited adrenal enzyme defects; over 90% are caused by 21-hydroxylase deficiency. 17-OHP is the primary diagnostic marker.

Classic CAH (severe): Presents in infancy. 17-OHP markedly elevated (often above 2,000–10,000 ng/dL or higher). The salt-wasting form causes dangerous electrolyte imbalance; newborn screening exists to catch this early and prevent life-threatening crises.

Non-classic CAH (mild): Presents in childhood, adolescence, or adulthood with androgen-excess symptoms. Baseline 17-OHP typically 200–1,000 ng/dL; confirmed by ACTH stimulation. Often misdiagnosed as PCOS. Manageable with low-dose glucocorticoids when treatment is indicated.

Newborn screening: Most countries screen for 17-OHP at birth. Premature or sick newborns often have false-positive screens. Confirmatory serum testing is required before a diagnosis is made.

WHEN IS 17-OHP TESTED?

Common clinical reasons for ordering 17-OHP:

Irregular or absent periods
Hirsutism, acne, or signs of androgen excess
Infertility evaluation
Suspected PCOS — to exclude non-classic CAH
Precocious puberty in children
Newborn with ambiguous genitalia or abnormal newborn screen
Monitoring treatment in known CAH
Evaluation of adrenal function

FAQ about 17-OH Progesterone

What is a normal 17-OH progesterone level for females?

Normal 17-OH progesterone in females depends on menstrual cycle phase. Follicular phase (days 1–12): approximately 15–70 ng/dL (0.5–2.1 nmol/L). Luteal phase (days 13–28): approximately 35–290 ng/dL (1.0–8.7 nmol/L). Postmenopausal: typically below 51–70 ng/dL. Always use the reference interval on your specific lab report — values differ between laboratories and test methods.
What does low 17-hydroxyprogesterone in females mean?

Low 17-OHP in females is most commonly a normal finding. In the early follicular phase levels are physiologically at their lowest. Women on combined oral contraceptives typically have suppressed 17-OHP. Low levels without symptoms of adrenal insufficiency do not require clinical action. If low 17-OHP accompanies fatigue, low blood pressure, or salt craving, cortisol and ACTH are the more appropriate tests to evaluate adrenal function.
What does 17-hydroxyprogesterone less than 50 mean?

A result of "< 50 ng/dL" means the measured level is below 50 — the assay's reporting threshold, not a zero value. For adult women in the follicular phase the normal range typically starts at 15–20 ng/dL, so a result below 50 ng/dL is within or below the normal range. This is a normal finding with no clinical significance in isolation.
Is 17-OH progesterone the same as progesterone?

No. They are different hormones with different functions. Progesterone is produced mainly by the ovaries to prepare the uterine lining for pregnancy. 17-OH progesterone is an adrenal and ovarian intermediate in the cortisol synthesis pathway. The two tests answer different clinical questions and are not interchangeable.
What is the normal range for 17-OH progesterone in ng/mL and nmol/L?

To convert ng/dL to ng/mL, divide by 100: follicular 15–70 ng/dL = 0.15–0.70 ng/mL; luteal 35–290 ng/dL = 0.35–2.90 ng/mL. To convert to nmol/L, multiply ng/dL by 0.0303: follicular 15–70 ng/dL ≈ 0.5–2.1 nmol/L; luteal 35–290 ng/dL ≈ 1.0–8.7 nmol/L.
What does high 17-OH progesterone mean in females?

High 17-OHP in females most commonly reflects non-classic CAH due to 21-hydroxylase deficiency, or mildly elevated levels from PCOS. A luteal-phase result can also appear elevated when compared against a general or follicular-phase range. Persistent follicular-phase elevation with androgen-excess symptoms warrants an ACTH stimulation test to evaluate for non-classic CAH.
What is the 17-OH progesterone LCMS normal range female?

For adult women tested by LC/MS-MS: follicular phase approximately 15–70 ng/dL (0.5–2.1 nmol/L); luteal phase approximately 35–290 ng/dL (1.0–8.7 nmol/L). LC/MS-MS ranges should not be compared against immunoassay ranges — the methods have different reference intervals. LabCorp test 500540 is their LC/MS-MS method.
What does elevated 17-OHP mean for PCOS?

In PCOS, 17-OHP may be mildly elevated from ovarian androgen production. The key question is whether the elevation represents non-classic CAH, which can present identically to PCOS. An ACTH stimulation test differentiates them: non-classic CAH typically produces a stimulated 17-OHP above approximately 1,500 ng/dL; PCOS typically produces only a mild increase below this threshold.
What does a high 17-OHP in a newborn mean?

High 17-OHP on newborn screening suggests possible classic CAH, which can cause life-threatening salt wasting if untreated. Many positives in premature or sick newborns are false positives — confirmatory serum testing, electrolytes, and clinical evaluation are required before diagnosis. A positive screen warrants prompt paediatric evaluation.
What is an ACTH stimulation test for 17-OHP?

The ACTH stimulation test measures 17-OHP at baseline and 60 minutes after synthetic ACTH injection. A stimulated level above approximately 1,500 ng/dL strongly suggests non-classic CAH. It is the gold standard for confirming non-classic CAH and distinguishing it from PCOS.
What does 17-OH Progesteron mean in German?

17-OH Progesteron (also 17-OH-Progesteron or Progesteron 17-OH) is the German term for 17-hydroxyprogesterone. German labs report in ng/dL or nmol/L: Follikelphase ~15–70 ng/dL (0.5–2.1 nmol/L); Lutealphase ~35–290 ng/dL (1.0–8.7 nmol/L). Erhöht = elevated; erniedrigt = low. Note cycle phase at collection when interpreting elevated results.
Why would 17-OH progesterone be low during the follicular phase?

Low 17-OHP in the follicular phase is usually physiologically normal — it is the lowest point in the cycle. Women on combined hormonal contraceptives have suppressed 17-OHP throughout the cycle. Women being treated for CAH with glucocorticoids have intentionally suppressed 17-OHP as a treatment goal. Low follicular-phase 17-OHP without symptoms is generally not clinically actionable.

What does it mean if your 17-OH Progesterone result is too high?

An elevated 17-OH progesterone result means more 17-OHP is accumulating than expected for the reference range applicable to your age, sex, and cycle phase.

For premenopausal women, the most important first step is confirming which cycle phase the blood was drawn in. A luteal-phase result can be 4–5× higher than a follicular-phase result and is entirely normal. If cycle phase was not documented, repeat testing in early follicular phase (days 2–5, early morning) is the most interpretable next step before any clinical action.

Persistent elevation in follicular phase (above 200 ng/dL): Warrants clinical evaluation. An ACTH stimulation test is used to distinguish non-classic CAH (stimulated 17-OHP typically above ~1,500 ng/dL) from PCOS (typically much lower stimulated response) and other causes of androgen excess.

Marked elevation (above 1,000 ng/dL adults; above 2,000 ng/dL in children/newborns): Strongly suggests classic or severe non-classic CAH. Prompt endocrinology evaluation warranted.

Method check: Was the result from LC/MS-MS or immunoassay? Immunoassay can be falsely elevated in borderline cases. If the result is borderline and was tested by immunoassay, confirmatory LC/MS-MS testing may resolve the question.

What does it mean if your 17-OH Progesterone result is too low?

A low 17-OH progesterone result is usually normal.

In premenopausal women, 17-OHP is physiologically lowest in the early follicular phase (days 1–5), typically 15–50 ng/dL or below. A result reported as "< 50 ng/dL" or "< 20 ng/dL" in this context is a normal finding.

In women on combined hormonal contraceptives, 17-OHP is typically suppressed throughout the cycle — a normal consequence of hormonal suppression, not a disorder.

In patients being treated for CAH with glucocorticoids, a low or suppressed 17-OHP is the treatment goal — it confirms adequate control of excess adrenal androgen production.

Low 17-OHP alongside symptoms of adrenal insufficiency (persistent fatigue, low blood pressure, salt craving, unexplained weight loss) should prompt cortisol and ACTH evaluation — these are more clinically relevant than 17-OHP alone for assessing adrenal function.

Fertility reassurance: Mildly low follicular-phase 17-OHP alone does not indicate infertility. Low 17-OHP is not a marker of poor egg quality, ovarian reserve, or implantation capacity — those require different tests (AMH, FSH, estradiol, progesterone in the luteal phase).

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.

What fantastic service and great, easy-to-follow layouts! I love your website; it makes it so helpful to see patterns in my health data. It's truly a pleasure to use. I only wish the NHS was as organized and quick as Healthmatters.io. You've set a new standard for health tracking!
