was wird beim check up ab 50 gemacht — which blood markers matter?

The health check-up for individuals aged 50 and above (e.g., Germany's 'Check-up 35+' recommended every three years) includes a medical history, physical exam, and a panel of blood markers. Key laboratory parameters are: **Lipid profile** (total cholesterol, LDL, HDL, triglycerides) to assess cardiovascular risk; **Fasting glucose or HbA1c** for diabetes screening; **Kidney function** (creatinine, eGFR); **Liver enzymes** (ALT, AST, GGT) to detect liver stress; **Thyroid-stimulating hormone (TSH)** if symptoms or risk factors are present; **Vitamin D** if deficiency is suspected; **Complete blood count** (hemoglobin, white cells, platelets) to screen for anemia or infection. For men, **PSA** is often discussed but not routinely recommended due to high false-positive rates. For women, **iron status** (ferritin) and **vitamin B12** may be relevant. Important: These markers are screening tools, not definitive diagnoses. Individual risk factors (family history, pre-existing conditions) determine the need for additional tests. A blood test alone does not replace medical consultation. Evidence for the benefit of these screenings in asymptomatic individuals is moderate, especially for lipid and glucose measurements. MyBody-X offers some of these markers, but interpretation should always be done by a physician.
