Luteinizing hormone (LH) is a glycoprotein adenotropin secreted by the basophilic bulb of the anterior pituitary gland. Is used to promote ovulation. Synergistic with FSH to form the corpus luteum and secrete progesterone. In general, the normal value of non-ovulation period is 5-25 miU/ml, less than 5 miU/ml, which is the time-cold syndrome caused by insufficient gonadotropin function. High FSH and high LH are markers of decreased ovarian function. If LH/FSH≥3, it is one of the basis for the diagnosis of polycystic ovary syndrome.
Detection range | sample size | Sample type | Test time |
0.2~160mIU/mL | 60μl | Whole blood / serum / plasma | 15min |
Corresponding items | index | Guiding significance | |
FSH,LH | ↑ | Common in primary gonadal lesions | Ovarian insufficiency, hypogonadism, primary amenorrhea, sexual dysfunction, dysplasia of the opposite sex, |
↓ | It mainly occurs in the pituitary or subthalamic amenorrhea, incomplete (physician) precocious puberty. | ||
Pituitary FSH tumor or LH tumor | Because of different tumor types, FSH and LH concentrations show different types of changes. | FSH tumors are mainly characterized by increased FSH, but LH may be normal. In LH tumors, LH was significantly elevated and FSH decreased. | In FSH/LH tumors, both FSH and LH are elevated. |
Concentration of FSH and LH in amenorrhea women | Effective difference between ovarian amenorrhea and pituitary or hypothalamic amenorrhea |
