What can the Hormoncheck Frauen tell you — and what not?

The 'Hormoncheck Frauen' is a consumer test that typically measures hormone levels (e.g., estradiol, progesterone, testosterone, cortisol) in saliva or blood. It can indicate cyclical patterns or outliers, but it does not diagnose medical conditions. The included DNA analysis (e.g., CYP2D6, VDR) has limited clinical utility: CYP2D6 variants affect drug and steroid metabolism, but hormone regulation is multifactorial (diet, stress, liver function). The test cannot assess fertility, menopause status, or disorders like PCOS or thyroid issues. Evidence for predictive value of such SNPs is weak (gwas, mechanistic). Without medical interpretation, results may mislead. Caution: Do not self-medicate based on these results.
