was kostet ein vitamin test beim arzt — which blood markers matter?

The cost of a vitamin test at a doctor varies widely. In Germany, statutory health insurance covers testing only if there is a justified suspicion of deficiency (e.g., chronic illness, malabsorption, or specific symptoms). Without medical indication, patients pay out-of-pocket: a vitamin D test costs about €20–30, while a comprehensive panel (D, B12, folate, B6, A, E) can range from €80–150. Which blood markers matter depends on the question: for general status, 25-hydroxy vitamin D, holotranscobalamin (active B12), serum folate, ferritin (iron), and possibly vitamin B6 (pyridoxal-5-phosphate) are useful. Vitamins A and E are only measured in special risk groups (e.g., fat malabsorption). Importantly, single tests without symptoms or risk factors are usually not evidence-based. The German Nutrition Society does not recommend routine screening in healthy individuals. Consumer tests like those from MyBody-X offer vitamin panels, but their clinical validity and cost-effectiveness should be critically evaluated. Always consult a doctor before paying for tests out of pocket.
