Common mistakes around Blutbild Senioren

Common mistakes around blood tests for seniors include: 1) Overinterpreting minor deviations that are physiologically normal in aging (e.g., slightly elevated CRP, lower hemoglobin). 2) Ignoring medication effects (e.g., aspirin lowers CRP, metformin depletes B12). 3) Unnecessary repeat testing without clinical indication. 4) Overlooking kidney function (eGFR) and vitamin D status, which are frequently abnormal in older adults. 5) Using reference ranges designed for younger adults instead of age- and sex-adjusted norms. The evidence for these pitfalls comes from clinical practice and guidelines, not from large RCTs. A blood test is a screening tool, not a diagnostic – abnormal results must be interpreted in clinical context. Direct-to-consumer labs often lack age-specific reference ranges, increasing misinterpretation risk.
