wie lange kann man eine stuhlprobe aufbewahren — which blood markers matter?

The question combines two distinct topics: stool sample storage and blood markers. For stool storage: most tests (e.g., microbiome analysis) recommend refrigeration at 2–8 °C and shipping within 24–48 hours. Longer storage (over 72 h) can alter bacterial composition and skew results. Freezing (−20 °C) is possible for some tests but not always standard. Which blood markers matter depends on the goal: for cardiovascular health, LDL, HDL, triglycerides, lipoprotein(a), and hsCRP are key; for inflammation, IL-6, TNF-α; for oxidative stress, glutathione, superoxide dismutase (SOD). The provided context contains no specific guidance on sample storage or blood markers. Evidence for storage times comes from lab practice, not controlled trials. For blood markers, evidence is strong for many (e.g., LDL, CRP), but there is no universal list – it is goal-dependent. Safety note: always consult a physician for interpretation of test results.
