How many days after implantation is beta-hCG detectable?a) 20 days after implantation b) 1-2 days after implantation c) 7-8 days after implantation d) 30 days after implantation

Answer 1

c) 7-8 days after implantation

Step-by-step explanation:

hCG or Human Chorionic Gonadotropin is used as a marker in pregnancy test kits. It is produced by the trophoblastic cells once the embryo has been implanted in the uterus. It becomes detectable in urine usually a week after implantation. Its level increases at the beginning of pregnancy up till 8-11 weeks and then falls off and becomes constant.
