【Product name】 LH Rapid Test Kit (Colloidal gold method)  

【Packaging specification】 1 test/bag，1/5/10/25/50 test(s)/kit  

【Intended use】 This product is used to detect the level of luteinizing hormone (LH) in women's  urine to predict the time of ovulation and to guide women of childbearing age to  choose the best time to conceive. Immunochromatographic detection of luteinizing hormone levels in women's urine  is a simple and rapid test technique. Luteinizing hormone (LH) is secreted by  pituitary basophils. In women, luteinizing hormone cooperates with follicle-stimulating hormone to maintain the menstrual cycle of the ovary, leading to ovulation  and corpus luteum formation. The production of luteinizing hormone is controlled  by hypothalamic gonadotropin-releasing hormone, and is regulated by positive and  negative feedback from the ovary. The peak of LH release during the menstrual  cycle is closely related to ovarian ovulation. Continuous monitoring of the concentration of LH in urine samples can reveal the changes of LH in women's urine. Once  the peak of gene production occurs, it indicates that the ovary is about to ovulate. 

【Testing principle】 The product adopts the principle of double antibody sandwich. When luteinizing  hormone is present in the sample, the LH antigen in the sample reacts with the  colloidal gold-labeled antibody (LH mAb1) on the binding pad to form a labeled  antibody-antigen complex. The complex is chromatographed upward by capillary  action and captured by the detection line (T line) antibody (LH mAb2) coated on a  nitrocellulose membrane, and a red band appears. The complex continues to be  chromatographed upwards and is captured by a control line (C line) antibody (goat  anti-mouse IgG polyclonal antibody) coated on a nitrocellulose membrane, and a  red band appears. The color depth of the T line in the detection area is positively correlated with the  LH content in the sample, and the LH content can be judged with the color scales of  different concentrations in the colorimetric card.
