Which Hormone is Detected in a Pregnancy Test

Question

Which hormone is detected in a pregnancy test?
A) human chorionic gonadotropin hormone made by the early embryo
B) progesterone made by the corpus luteum
C) luteinizing hormone made by the pituitary
D) estrogen made by the ovary

Accepted Answer

Pregnancy tests detect human chorionic gonadotropin (hCG) hormone, which is made by the early embryo and later by the placenta during pregnancy. This hormone can be detected in a woman's urine or blood and indicates that she is pregnant. Progesterone, luteinizing hormone, and estrogen are all involved in the menstrual cycle but are not used to detect pregnancy.
