β-HCG is a fluorescent immunoassay for the quantitative measurement of β-HCG level in human serum and whole blood. This test is performed to help diagnose pregnancy if a woman is to undergo a medical treatment, be placed on certain drugs, or have other testing, such as x-rays, that might harm the developing baby.

Product Detail

Introduction
β-HCG Rapid Quantitative Test is used to detect the concentration of β-HCG in human serum or plasma.
HCG (Human chorionic gonadotropin) is a kind of glycoprotein hormone secreted by placental trophoblast cells. It can maintain the level of corpus luteum and decrease the activity of the mother lymphocyte, which prevents the embryo from immune rejection. HCG consists of an α subunit and a β subunit. The concentration of β subunit of HCG is used to represent the concentration of HCG in human blood. The concentration of β-HCG is up to 27000-210000mIU/mL from the eighth week to the twentieth week of pregnancy. It will drop down to 8000-60000mIU/mL at the eighteenth week of pregnancy. The detection of β-HCG can represent the summation of HCG and free β-HCG[1-3].
