What is the Hormonal Basis of the Pregnancy Test

Question

What is the hormonal basis of the pregnancy test?
A) Estrogen
B) Prostaglandin
C) Oxytocin
D) Human chorionic gonadotropin (hCG)

Accepted Answer

The hormonal basis of the pregnancy test is Human chorionic gonadotropin (hCG), a hormone produced by the placenta after fertilization occurs. The presence of hCG in urine or blood indicates pregnancy, which is detected by home pregnancy tests or laboratory tests. Therefore, option D is the best choice. The other options, estrogen, prostaglandin, and oxytocin may have roles in pregnancy, but they are not used for pregnancy testing.
