Immature granulocytes (IGs) are developing white blood cells that are part of the body’s innate immune system, the fast-acting branch of immunity that responds quickly to infections and tissue injury. They are precursors to mature granulocytes (especially neutrophils), and typically include cells such as:
Myelocytes
Metamyelocytes
(Sometimes promyelocytes, depending on the analyzer/reporting method)
Under normal conditions, these cells remain inside the bone marrow, where blood cells are produced and mature before being released into circulation.
IG% reports the proportion of immature granulocytes out of your total white blood cell count. It is commonly generated automatically by modern hematology analyzers as part of a CBC with differential.
Many labs also report:
Immature Granulocytes (absolute) (IG#), which is the actual number of immature granulocytes per volume of blood
Both values can be helpful, because IG% can rise either due to:
more immature cells being released, or
changes in other white blood cell types that shift the percentage
Immature granulocytes are often considered a sign of increased bone marrow activity, meaning your body is rapidly producing and releasing infection-fighting cells. This can happen early in the course of illness and may appear before other classic findings, such as a significantly elevated total white blood cell count.
IG% is most useful as a supporting marker when clinicians are evaluating or monitoring:
suspected bacterial infection
systemic inflammation
immune system stress (e.g., major illness, trauma, surgery)
response to treatment over time
Reference ranges vary slightly by lab and by age, but in many healthy adults, IG% is very low (often near zero).
A mild elevation can be transient and not always dangerous. However, higher values—especially when persistent or paired with symptoms—can be clinically meaningful.
In many clinical contexts, IG% above ~2–3% is considered more concerning and may raise suspicion for significant infection or systemic inflammation, particularly in acutely ill patients.
An elevated Immature Granulocytes (%) result generally means your bone marrow is responding to a stressor by releasing immature white blood cells into the bloodstream. Common causes include:
One of the most common reasons for elevated IG% is infection, such as:
pneumonia
urinary tract infection
skin and soft tissue infection
bloodstream infection (bacteremia)
sepsis (in more severe cases)
In some cases, IG% can rise early and help clinicians recognize infection sooner—especially when combined with symptoms, vital signs, and other lab markers.
IG% may increase in inflammatory states, including:
autoimmune disease flares
severe inflammatory reactions
inflammatory lung or systemic conditions
IG% can rise when the body is under strain, including:
major surgery
trauma or burns
severe illness requiring hospitalization
low oxygen states (hypoxia)
acute cardiovascular stress in some settings
Immature granulocytes can appear during periods of high bone marrow demand or rebound, such as:
recovery after a serious infection
recovery after chemotherapy or marrow suppression
treatment with medications that stimulate blood cell production (in some cases)
Certain factors may increase IG% without a dangerous infection, including:
corticosteroid therapy
pregnancy (mild changes can occur)
IG% itself does not cause symptoms. Symptoms depend on the underlying cause. If IG% is elevated due to infection or inflammation, people may experience:
fever or chills
fatigue or weakness
body aches
cough or shortness of breath
sore throat
urinary pain or frequency
abdominal pain
rapid heart rate
confusion (especially in severe infection)
If you have high IG% plus symptoms of serious infection, it should be evaluated promptly.
IG% is rarely interpreted alone. Providers typically look at it alongside:
Total WBC count (high, normal, or low)
Neutrophils (often elevated in bacterial infection)
Bands / left shift (if reported separately)
Lymphocytes (may change in viral illness or stress)
CRP and/or procalcitonin (inflammation and infection markers)
Clinical symptoms and vital signs (fever, blood pressure, heart rate, oxygen levels)
A high IG% may be especially concerning when paired with:
high fever
low blood pressure
fast heart rate
confusion
worsening shortness of breath
rising CRP or procalcitonin
abnormal lactate (in suspected sepsis)
Yes. While infection is common, IG% can rise from non-infectious causes such as inflammation, stress, or medication effects. This is why IG% is best viewed as an early warning signal, not a standalone diagnosis.
Immature Granulocytes (%) is an early marker of bone marrow activation and immune response. In healthy adults, it is usually very low. When elevated, it often suggests infection or inflammation, but it can also rise due to physiologic stress, medication effects, or bone marrow recovery. The result is most meaningful when interpreted with your symptoms, other CBC findings, and follow-up testing if needed.
Immature granulocytes (IGs) are early-stage white blood cells released from the bone marrow before full maturity. On a complete blood count (CBC) with differential, an IG percentage above 2% of total white blood cells is generally considered elevated and may indicate infection, inflammation, or other causes of increased bone marrow activity.
An elevated IG count is often an early immune system signal, sometimes appearing before other white blood cell changes. It reflects the bone marrow’s rapid response to increased demand for immune cells.
Common causes of high immature granulocytes include:
Bacterial infections (e.g., sepsis, pneumonia)
Acute inflammatory disorders (e.g., autoimmune flares)
Cancer, especially bone marrow metastases
Tissue necrosis (e.g., heart attack, severe injury)
Acute transplant rejection
Trauma or major surgery (orthopedic or general)
Myeloproliferative neoplasms
Steroid therapy
Pregnancy
Special populations:
Newborns and premature infants often have naturally higher IG levels due to immature immune systems.
Elderly patients or those with myelosuppression may show elevated IG without increased neutrophils.
While high IG levels are a sensitive early marker, they should not be used alone to diagnose infection or sepsis. Their accuracy improves when combined with other markers such as:
C-reactive protein (CRP)
Cytokine profiles
Interleukin levels
IG measurement is especially useful for monitoring disease progression or treatment response after a diagnosis has been made.
Pediatric caution: In infants—particularly premature newborns or those under seven days old—interpretation must be cautious due to natural immune immaturity.
An IG% above 2% can indicate that your bone marrow is actively producing and releasing immature white blood cells in response to infection, inflammation, tissue damage, or other stressors. It is best interpreted alongside other lab values and the clinical picture by a healthcare provider.

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.
