24 Hour Urine Iodine

Sample type: Urine
Optimal result: 0.1 – 0.45 ug/mg creatinine

Elevated levels of iodine in the "24 Hour Urine Iodine" test can indicate excessive iodine intake. High iodine levels can sometimes lead to conditions such as hyperthyroidism or thyroiditis, where the thyroid gland becomes overactive or inflamed. Excess iodine can disrupt normal thyroid function, potentially causing a range of symptoms from weight loss to heart palpitations. It's important to monitor iodine intake, especially in areas where iodine supplementation is common, such as iodized salt. For a detailed understanding of high iodine levels and their implications, consulting a healthcare professional is recommended.

Low levels of iodine, as measured by the "24 Hour Urine Iodine" test, can indicate iodine deficiency. This deficiency can lead to various health issues, including thyroid gland dysfunction, which can manifest as hypothyroidism, goiter, and in severe cases, developmental delays in children. Iodine is essential for the synthesis of thyroid hormones, which regulate metabolism, growth, and development. Low iodine levels can also impact immune response and estrogen metabolism. It's crucial to address iodine deficiency to maintain overall health and prevent these complications. For more detailed information, it's advisable to consult a healthcare provider or visit the Doctor's Data Laboratory website.

The "24 Hour Urine Iodine" test offered by Doctor's Data Laboratory is a diagnostic tool used to evaluate iodine levels in the body. This test is essential for assessing thyroid gland function, immune response, and estrogen metabolism. Iodine is a crucial element required for normal thyroid function and overall health, including metabolic regulation and neurological development. Insufficient iodine can lead to issues like thyroid deficiency, weight gain, loss of energy, goiter, and impaired mental function.

Insufficient iodine can lead to issues like thyroid deficiency, weight gain, loss of energy, goiter, and impaired mental function. The test can be performed with a conventional 24-hour urine collection or after a loading dose of iodide/iodine. It measures iodine using ICP-MS, a method also used by the CDC, and assesses iodine status by evaluating the percentage of the ingested dose excreted in urine. Low excretion suggests greater bodily retention and potential need for iodine. For more detailed information, you can visit the Doctor's Data website.

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
