Early pregnancy test paper

Human chorionic gonadotropin (HCG) is a glycoprotein produced by the placenta during pregnancy and can be excreted from the urine through the glomeruli, so measuring HCG in urine is a reliable indicator for diagnosing pregnancy. The colloidal gold test strip for early pregnancy uses nano-colloidal gold technology, and uses a chromatographic double antibody sandwich method to detect the concentration of HCG in urine to determine whether it is pregnant. The goal is to detect early pregnancy.
