Common mistakes around Haarausfall Labor

Common mistakes around hair loss lab tests: Many consumers order direct-to-consumer DNA tests claiming to reveal genetic risks for hair loss. However, the evidence for such tests is often weak or purely marketing-driven. Single SNPs (e.g., in the AR gene) typically have small effect sizes and are insufficient for clinically meaningful predictions. Another mistake is testing only hormones (e.g., DHT) while ignoring other causes like iron deficiency, thyroid dysfunction, or inflammation. The timing of blood draws (circadian rhythms) is also frequently overlooked. Furthermore, many tests lack medical oversight – results are interpreted without clinical context. Safety note: Sudden or patchy hair loss should always be evaluated by a physician to rule out serious conditions. Evidence: practice/marketing.
