welche untersuchungen ab 50 — which blood markers matter?

There is no universal list of blood markers that applies to everyone over 50 – the choice should be individualized based on risk factors, pre-existing conditions, and family history. In primary care, common recommendations include: lipid panel (total, LDL, HDL cholesterol, triglycerides), fasting glucose or HbA1c, vitamin D, vitamin B12, ferritin, TSH, creatinine with eGFR, liver enzymes (ALT, AST, GGT), and a complete blood count. For men, PSA may be discussed; for women, calcium and phosphate may be relevant for bone health. Inflammatory markers like hs-CRP are optional. The evidence for routine screening of many of these markers in asymptomatic individuals is moderate to weak – many recommendations are based on expert consensus (e.g., US Preventive Services Task Force) or observational studies, not on randomized controlled trials. A comprehensive 'check-up' without specific indication can lead to overdiagnosis and false positives. A risk-adapted approach is more sensible, e.g., based on cardiovascular risk score (SCORE2) or diabetes risk. MyBodyX tests do not offer specific blood marker analysis for age 50+; they focus on genetics and microbiome. Anyone wanting specific blood work should discuss it with their primary care physician.
