A new method accurately measures long-term hormone levels in hair.
research Revisiting hyper- and hypo-androgenism by tandem mass spectrometry
The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.
research MANAGEMENT OF ENDOCRINE DISEASE Hyperandrogenic states in women: pitfalls in laboratory diagnosis
Diagnosing hyperandrogenism in women is complex and requires accurate testing methods and consideration of SHBG levels.
research Isotope Dilution-Based Targeted and Nontargeted Carbonyl Neurosteroid/Steroid Profiling
Researchers created a new method to measure brain steroids, finding higher levels of certain steroids and changes due to a drug.
research Insights From Liquid Chromatography-Mass Spectrometry-Measured Androgens in Indian Women With Polycystic Ovary Syndrome
Androstenedione is better than testosterone for diagnosing PCOS in Indian women.
