24-hour urine iodine test to assess iodine levels and thyroid function.
Specialty biomarker testing measures advanced markers that go beyond standard blood panels to provide deeper insight into specific biological pathways. These tests are commonly used in functional and integrative medicine to identify root causes of symptoms, assess cellular health, and guide personalized treatment protocols. Markers like IGF-1 reflect growth hormone activity and aging, lipoprotein(a) reveals inherited cardiovascular risk invisible to standard lipid panels, and neurotransmitter profiles can explain mood and cognitive symptoms. Results enable highly targeted interventions that standard tests would miss.

Who Is This For?
People working with functional or integrative medicine practitioners. Those seeking root-cause analysis beyond standard blood work. Longevity enthusiasts tracking advanced biomarkers. Anyone with persistent symptoms despite normal standard labs.
What's Included
Preparation Required
Fasting may be required depending on the specific marker. Follow your clinic's instructions. Some tests require morning samples for accurate results. Bring a list of all supplements — many affect these markers.
Biomarkers Tested
4Total urine volume collected over 24 hours.
Creatinine is a waste product from muscle use and meat digestion. Healthy kidneys remove it from blood, excreting it in urine. This helps assess kidney function.
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.
Iodine levels can be adjusted for urine dilution using creatinine. This adjustment accounts for differences in urine volume or concentration and allows for a more accurate assessment of iodine status.
