Early Pregnancy Hormone Blood Test

The Pregnancy Hormone Test measures progesterone levels to confirm ovulation, assess fertility, and monitor early pregnancy. Progesterone is often called the “pregnancy hormone” because of its critical role in preparing the uterus for implantation and maintaining early pregnancy. Produced primarily by the corpus luteum (temporary gland formed after egg release), progesterone levels rise significantly after ovulation, thicken the uterine lining, and create optimal conditions for embryo implantation. This test is essential for women trying to conceive, investigating irregular periods or infertility, monitoring fertility treatments, and assessing early pregnancy viability.
