Start testing your BiomarkersUrinary iodine excretion reflects recent dietary intake (>90% of ingested iodine is excreted in urine). A random urine sample is widely used to screen iodine sufficiency. Use alongside thyroid markers (TSH, T4, T3) and serum iodine when a more complete nutrient picture is needed.
Random urine iodine reflects recent intake (hours to days), not long-term reserves; a single value can vary widely day-to-day. Iodine-containing contrast agents, kelp supplements, and certain medications can significantly elevate results. Interpret alongside thyroid markers and clinical context.

Advanced biomarkers for deeper health analysis
A multi-cancer early detection blood test from GRAIL that looks for a cancer signal and, when detected, reports the most likely tissue or organ of origin. This is an adjunct screening test, not a standalone diagnosis.
Metals Panel 2, Urine (Csa) is a focused urine heavy metals test that quantifies arsenic and mercury—two common environmental toxins—using creatinine correction to account for hydration. This panel helps identify exposures that can drive oxidative stress, endothelial dysfunction, and cardiometabolic strain tied to hypertension and vascular aging.
The most comprehensive GLP-1 medication monitoring panel available. 131 biomarkers across metabolic, hormonal, nutritional, pancreatic, kidney, and inflammatory categories — designed for patients and prescribers who want nothing left to chance.
Standard 2-tier Lyme disease screening with IgG and IgM immunoblot antibodies. Detects immune response to Borrelia burgdorferi, the bacteria that causes Lyme disease. Recommended if you live in or travel to tick-endemic areas, or have unexplained fatigue, joint pain, or neurological symptoms.
