Abstract

The invention relates to a kit for detecting 12 steroid hormones in serum by using an ultra-high performance liquid chromatography-tandem mass spectrometry technology. The kit is characterized in thata serum sample is mixed with a mixed internal standard solution of all to-be-detected substances, the sample does not need derivatization treatment, and a to-be-detected solution can be obtained justby one-step liquid-liquid extraction; electrolyte ammonium fluoride is added into a mobile phase, so that the ionization efficiency of certain target compounds can be effectively improved; and 12 hormones are simultaneously detected by adopting a mass spectrum positive-negative switching scanning mode. The kit has the advantages of high sensitivity, high specificity, low cost and simple and quickpretreatment process, does not need solid-phase extraction or derivation, can complete the separation and detection of 12 hormones within 5.0 minutes, and provides a reliable detection kit for the health assessment of clinical endocrine diseases.

Description

technical field [0001] The invention belongs to the technical field of blood detection, and in particular relates to a kit for detecting 12 steroid hormones in serum by ultra-high performance liquid chromatography tandem mass spectrometry. Background technique [0002] Steroid hormones are a class of fat-soluble small molecule hormones, also known as steroid hormones. They are produced by cholesterol through a series of enzyme-catalyzed metabolism, and play an important role in regulating the body's metabolism, immune regulation, sexual function regulation, growth and development, etc. Steroid hormones can be divided into progestins, mineralocorticoids, glucocorticoids, estrogens, and androgens according to their physiological functions. Progesterone, corticosterone, and aldosterone are mineralocorticoids; 17α-hydroxyprogesterone and cortisol are glucocorticoids; estrone and estradiol are estrogens; dehydroepiandrosterone sulfate, dehydroepiandrosterone, testosterone, Both...
