welche blutwerte check up — which blood markers matter?

A general blood check-up should be tailored to individual risk factors. Key markers include: complete blood count (hemoglobin, white cells, platelets), fasting glucose and HbA1c (diabetes screening), lipid panel (total, LDL, HDL cholesterol, triglycerides), liver enzymes (ALT, AST, GGT), kidney function (creatinine, BUN), thyroid panel (TSH, possibly free T3/T4), and vitamin D, vitamin B12, and ferritin (iron status). These cover common deficiencies and metabolic issues. However, lab results alone are insufficient without clinical context – many 'normal' ranges are population-based and not personalized. Evidence for broad screening in asymptomatic individuals is moderate; stronger recommendations exist for specific groups (e.g., elderly, pregnant women). Caveat: over-testing can lead to unnecessary anxiety or interventions. A targeted check-up after medical consultation is more valuable than a generic panel.
