Healthcare professionals should assess biochemical hyperandrogenism using validated tandem mass spectrometry (LC-MS/MS) for testosterone, avoiding direct immunoassays due to their limited accuracy.

When getting blood work for PCOS, ensure your doctor orders testosterone testing via 'tandem mass spectrometry' (LC-MS/MS). This is the gold standard for accuracy. Avoid standard immunoassays if possible.

GoodSupportsHIGH confidence
Laboratories should use validated, highly accurate tandem mass spectrometry (LC-MS/MS) assays for measuring total testosterone... Laboratories should use LC-MS/MS assays over direct immunoassays... which have limited accuracy and demonstrate poor sensitivity and precision for diagnosing hyperandrogenism in PCOS.
