Luteinizing Hormone (LH)

Luteinizing hormone is involved in promoting ovulation induction by follicle stimulating hormone, promoting the formation and secretion of estrogen and progesterone, promoting testicular synthesis and secretion of androgens. Basic Information Specialist classification: examination classification: endocrine examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in pituitary dysfunction, ovarian function decline, hypothalamic amenorrhea, secondary sexual dysfunction. Normal value: Male: 1.2-7.8U/L Female follicular phase: 1.65-15U/L Luteal phase: 0.61-16.3 U/L Ovulation period: 21.9-56.6U/L Menopause: 14.2-52.3U/L Above normal: Found in central precocious puberty, polycystic ovary syndrome, pituitary amenorrhea, congenital ovarian hypoplasia, congenital testicular hypoplasia, oophorectomy, women's menopause. negative: Positive: Tips: It is recommended to check the first 2-3 days of the predicted peak (14-18 days before menstruation). Normal value Male l.2 ~ 7.8U / L. Female follicular phase l.65 ~ 15U / L, luteal phase 0.61 ~ 16.3U / L, ovulation period 21.9 ~ 56.6U / L, menopause 14.2 ~ 52.3U / L. Clinical significance (1) rise Turner syndrome (gonadal dysplasia syndrome), Klinefel-ter syndrome (testicular dysplasia syndrome), testicular feminization, gonadectomy, gonadal stimulating hormone tumor, polycystic ovary syndrome, etc. . (2) lower Anterior pituitary dysfunction, Sheehan syndrome (Siehan syndrome), anorexia nervosa, Kallmann syndrome (olfactory loss-type testosterone syndrome), LaurenceMoon-Biedl syndrome (sexual naive-retinal retinitis) - Multi-finger, toe deformity syndrome), sex hormone tumors, HCG (human chorionic gonadotropin) tumors, adrenal allodynia syndrome, and the like. High results may be diseases: premature child breast hypertrophy, luteal insufficiency infertility, pituitary adenoma, high testosteroneemia, precocious puberty Before the inspection: Make sure that the ovulation monitoring test paper must be purchased at a regular pharmacy, and it is produced by a regular pharmacy. At the time of inspection: First, the LH peak in the menstrual cycle is a relatively short period of time, from 48 to 50 hours from the beginning to the end. LH is quickly cleared from the body and usually only appears positive in one day, sometimes for two consecutive days. Therefore, in order to detect the LH peak, it should be tested daily. It is recommended to perform the first 2~3 days of the predicted peak (14~18 days before menstruation). Second, the results of urine LH measurements are very sensitive to fluid intake and measurement time, but there is no need to limit intake, just try to avoid heavy drinking in a short time before testing. Third, in theory, the first morning urine is the best test specimen because the urine is most concentrated at this time. But in fact, if only once a day, the most effective measurement time is 3-8 o'clock in the afternoon, during which time the LH peak of 90% of the ovulation cycle can be monitored. Monitoring more than once a day can also increase the detection rate, but an increase in the number of monitoring will also increase the cost. Inspection process Test with ovulation monitoring test paper. Not suitable for the crowd Nothing. Adverse reactions and risks Nothing.
