Question

which hormone levels are checked using a urine pregnancy kit to confirm a pregnancy?

a. human chorionic gonadotropin

b. estrogen

c. progesterone

d. testosterone

Explanation:

Urine pregnancy kits detect human chorionic gonadotropin (hCG). hCG is produced by the placenta after implantation of the fertilized egg in the uterus. Estrogen and progesterone are involved in the menstrual cycle and pregnancy maintenance but are not the hormones specifically targeted by pregnancy kits. Testosterone is a male - dominant hormone (though females have small amounts) and is not related to pregnancy detection in this context.

Answer:

A. human chorionic gonadotropin
