was sind hb werte — which blood markers matter?

Hb (hemoglobin) values are a core blood marker reflecting oxygen-carrying capacity. Normal ranges are roughly 13.5–17.5 g/dL for men and 12.0–15.5 g/dL for women. Low Hb indicates anemia; high Hb suggests polycythemia. However, the full picture matters: MCV, MCH, RDW, ferritin, transferrin saturation, and vitamin B12/folate status help differentiate causes (iron deficiency, chronic disease, vitamin deficiency). Inflammatory markers like CRP also affect interpretation. DNA tests cannot measure current Hb levels, but genetic variants in HBB (sickle cell disease) or HFE (hemochromatosis) are clinically relevant. The evidence for Hb as a clinical marker is human-strong, but interpretation requires a physician. MyBody-X tests do not directly measure Hb; they focus on DNA, microbiome, or food IgG. For a complete blood count, a lab visit is necessary.
