wieviel gene hat der mensch — which blood markers matter?

Humans have approximately 20,000–25,000 protein-coding genes, according to the Human Genome Project and ongoing annotations (e.g., GENCODE). Thousands of non-coding RNA genes and regulatory elements exist as well. The exact count is fluid as gene definitions evolve. – Which blood markers matter depends on your health goals. Common important markers include: complete blood count (hemoglobin, white cells, platelets), lipid panel (LDL, HDL, triglycerides), fasting glucose and HbA1c, liver enzymes (ALT, AST, GGT), kidney function (creatinine, BUN), thyroid hormones (TSH, free T4), vitamin D, ferritin, and hs-CRP. MyBody-X DNA tests can indicate genetic predispositions for certain metabolic pathways, but they do not replace blood testing. Individual gene variants usually have small effects; lifestyle and environment are far more influential. Consult a physician to determine which blood markers are relevant for your personal health profile.
