welche blutwerte sind wichtig — can a DNA test help?

Important blood values include complete blood count, lipid panel (LDL, HDL, triglycerides), fasting glucose, HbA1c, vitamin D, ferritin, TSH, liver and kidney markers, and inflammatory markers like CRP. A DNA test can provide genetic insights into predispositions—for example, variants in APOE or PCSK9 affecting cholesterol, GC/VDR for vitamin D, or MTHFR for folate metabolism. However, effect sizes are generally small, and lifestyle factors dominate. DNA tests cannot diagnose or replace blood work; they only indicate potential risk. Evidence is often mechanistic or from GWAS with modest associations. Many consumer claims are exaggerated. For accurate assessment, regular blood tests are essential. Caveat: Do not base medical decisions solely on genetic results. The evidence level for most DNA-blood value links is mixed or unclear. In summary, DNA tests can complement but never substitute clinical blood measurements.
