Quantification of steroid hormones in low volume plasma and tissue homogenates of fish using LC-MS/MS.

ABSTRACT: Quantification of steroid hormones in fish is an important step for toxicology and endocrinology studies. Among the hormone analysis techniques, liquid chromatography tandem mass spectrometry (LC-MS/MS) has widely been used for measuring hormones in various biological samples. Despite all improvements in the technique, detection of several hormones in a low volume of serum or plasma is still challenging. We developed a robust method for simultaneous quantification of 14 steroid hormones including corticosterone, cortisol, 11-ketotestosterone, progesterone, testosterone, 17OH-progesterone, aldosterone, dihydrotestosterone, estrone, 17β-estradiol, estriol, ethinylestradiol, levonorgestrel and equilin from volumes as low as 10 µL serum or plasma in a short run by LC-MS/MS. The lowest limit of
