Start testing your BiomarkersIGFBP-3 is the principal binding protein for insulin-like growth factor 1 (IGF-1) and reflects integrated GH-IGF axis activity. Measured alongside IGF-1, it can help interpret growth hormone status, support evaluation of GH deficiency or excess, and provide additional context for longevity, body composition, and metabolic discussions with your clinician.
IGFBP-3 varies with age, sex, nutrition, liver function, and certain medications—interpret in context. Acute illness, prolonged fasting, hepatic dysfunction, and GH/IGF-modulating treatments can shift levels. Use alongside IGF-1 and clinical assessment.

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.
