Urine iodine test to detect abnormal iodine levels, indicating deficiency or toxicity.

Additional Information

This test measures the level of iodine in your urine. Iodine is crucial for thyroid hormone production (T3 and T4), regulating metabolism, growth, and development. Low levels may signal deficiency, while high levels can indicate excess supplement use or food consumption, potentially causing thyroid dysfunction. This test helps assess iodine balance in your diet and identify potential health risks.

Biomarkers Tested (1)

Urine Iodine (µg/L)
Iodine is an essential trace element and an integral component of thyroid hormones. Thyroid hormones are required for normal growth and development of tissues and maturation of our bodies. Approximately 80% of iodine is excreted in the urine, making it a good marker of the previous day's intake.
