What should I know about vitamin und mineralstoff test?

A vitamin and mineral test (e.g., via capillary blood) measures the concentration of selected micronutrients in your blood. While it can provide a rough snapshot, its limitations are significant: blood levels often reflect recent intake rather than long-term tissue stores. For many nutrients, standardized reference ranges are lacking, and results can be skewed by time of day, last meal, or supplements. Evidence for the benefit of such testing in healthy, asymptomatic individuals is weak – it is often marketed as a wellness tool rather than a medical necessity. A clinically relevant deficiency should always be diagnosed by a physician through history, physical exam, and confirmatory lab work. ISO certification ensures lab accuracy, not clinical validity. If you choose to test, interpret results cautiously and do not base supplementation solely on them. A balanced diet typically meets requirements; targeted medical checks are more appropriate for at-risk groups like vegans or pregnant women.
