How do home-based pregnancy tests work?
Pregnancy test kits detect the presence of the human chorionic gonadotropin hormone (hCG) in the urine or blood sample of a pregnant woman.
hCG is formed by the placenta after implantation of the fertilised egg in the uterus. This happens after six days of conception. The levels of hCG rise with each passing day of pregnancy.
Home-based pregnancy tests utilise urine samples to detect the hCG while hCG in blood is detected by visiting a doctor.
Home pregnancy test kits which detect the presence of the human chorionic gonadotropin hormone (hCG) in the urine are easy to perform. Women usually use home pregnancy test kits before visiting their doctor.
