Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell‒stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (FSH).
LH Rapid Quantitative Test (Chemiluminescence Immunoassay) is used for in vitro quantitative detection of the Luteinizing hormone (LH) concentration in human serum and plasma that contains heparin /EDTA and other anticoagulants samples, mainly used for auxiliary diagnosis of reproductive hormones diseases.
