The researchers reported a case of falsely elevated testosterone in a teen, due to immunoassay interference, demonstrating that liquid chromatography tandem-mass spectrometry provides more accurate testosterone measurement, emphasizing the need for thorough analysis when clinical results are inconsistent.

This study measured estradiol and progesterone in the scalp hair of pre- and postmenopausal women using immunoassay, but found no statistical significance in hormone concentration differences between the groups.

This study emphasizes the necessity of confirming elevated testosterone levels detected by immunoassay with liquid chromatography-tandem mass spectroscopy before pursuing more complex diagnostic evaluations.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This study found that women with polycystic ovary syndrome in China had elevated androgen levels compared to healthy controls, and suggests body weight management and SHBG and FAI testing are recommended for these women.
