About this treatment
The Vitamin B12 assay determines circulating B12 concentration, which may be useful for evaluating fatigue, neurological symptoms, or dietary adequacy. The test uses a standard venous blood sample with no fasting required, and results are typically returned within a few business days. At $130 you receive the blood draw, lab analysis of the B12 marker, and a clear report explaining your level and potential dietary or supplemental recommendations. Ideal for individuals with dietary restrictions or unexplained fatigue.
