Semiquantitative detection system for luteinizing hormone and detection method thereof

Abstract

The invention discloses a semiquantitative detection system for luteinizing hormone and a detection method thereof. The system is composed of a test strip reading meter and a colloidal-gold test strip. The test strip reading meter can semiquantitatively detect the color depth of a detection line on the colloidal-gold test strip of regular molecules and total molecules of the luteinizing hormone, test results within a period of time are drawn into a curve on an LCD of a detector, the peak period of the luteinizing hormone is prompted, and the ovulation time is accurately judged. The test strip reading meter comprises a power switch, a single chip microcomputer, a motor, a light emitting diode, a photoelectric sensor, a power amplifier, an A / D converter, the LCD, a storer and a key. Visual testing is not needed, detection results are more accurate and are not affected by the intensity of ambient light and vision, testing is automatic and accurate, the color depth records can be drawn into a curve on the LCD on the detector, and therefore one ovulation period is judged.

Description

technical field [0001] The invention belongs to the field of medical testing reagents, and relates to a semi-quantitative detection system of luteinizing hormone and a detection method thereof. Background technique [0002] Luteotropic hormone (luteotropichormone), abbreviated as LH, is a glycoprotein hormone secreted by basophils in the anterior pituitary gland, and is called gonadotropin together with FSH. The main physiological role of LH is to promote the rupture of mature follicles and ovulation in women of childbearing age. A peak of LH secretion can be observed in the mid-menstrual period, that is, about 24 hours before ovulation, and its value is 8-10 times higher than that in the follicular period. The LH level after ovulation rapid decline. After follicular ovulation, LH can promote the production of corpus luteum, and make the corpus luteum secrete estrogen and progesterone; for men, it mainly promotes the proliferation of interstitial cells in the testis, so it ...

AI Technical Summary

Problems solved by technology

Since the test line and the quality control line on the reaction film of the test paper are directly in contact with the air, the test solution will be volatilized, and the external liquid is easy to penetrate into the reaction layer, which will affect the test results. The large visual error will affect the test results. At the same time, it cannot Record the results of the color depth and draw it into a curve to judge the ovulation period
