β-hCG Rapid Detection Kit

β-hCG is a glycoprotein secreted by the trophoblast cells of the placenta, consists of alpha- and beta-dimerized glycoproteins. The α-subunit is common to anterior pituitary hormones; the     β-subunit is specific to β-hCG.The main function of β-hCG is to stimulate the corpus luteum, favoring the sustained secretion of estrogen and  luteinizing hormone in order to promote uterine metamorphosis and the growth and maturation of the placenta. The modern belief is that HCG is produced by trophoblast transitional and syncytiotrophoblast cells. It proliferates rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of gestation, β-hCG gradually declines until it reaches relative stability at about 20 weeks.Currently,  the  following  tests  are   commonly  used:  latex   set   inhibition  test   and  hemagglutination  inhibition  test; radioimmunoassay (RIA); enzyme-linked immunosorbent assay (ELISA); and colloidal gold test with monoclonal antibodies.
