welche blutwerte check up — what are common causes?

Common causes of abnormal blood values in a routine check-up are mostly lifestyle-related: diet (e.g., high lipids, uric acid), lack of exercise, obesity, smoking, alcohol, and medications. Acute or chronic infections, inflammation, kidney or liver dysfunction, and thyroid disorders can also shift values. Genetic factors such as APOE variants (higher LDL) or MTNR1B polymorphisms (slightly elevated fasting glucose) play a minor role – they explain only a small fraction of variance. Direct-to-consumer tests often overstate the clinical relevance of single SNPs. A blood panel alone is not diagnostic; deviations must be interpreted in the full context (age, sex, comorbidities, medications). Persistent abnormalities warrant medical evaluation.
