What is a Serum Progesterone Test?
- Progesterone is a hormone that affects a woman’s ability to become and remain pregnant.
- A serum progesterone test measures the level of progesterone in your blood.
- Abnormally high or low progesterone levels can be a sign of several health problems.
Progesterone is a hormone which the female body produces to conceive. The Progesterone hormone is formed in the ovaries, hence women produce this hormone and have considerably higher levels of progesterone compared to men. A Progesterone Blood Test calculates the amount of progesterone levels in the bloodstream. While in case of men, the role of Progesterone hormone is to create or generate sperms also called as spermatogenesis.
In women, if the body has good levels of Progesterone, she can conceive easily while fluctuating high or low levels of Progesterone is an indication of health issues that might arise. In women, progesterone hormone helps the uterus to create fertilized eggs. Healthy levels of Progesterone helps to survive the pregnancy. Progesterone suppresses ability to produce milk during pregnancy. When a woman is about to deliver or is in labor, the progesterone levels considerably drop, to generate the milk production.
To check the progesterone levels in your blood, your doctor can suggest you to go for a serum progesterone test also called as progesterone blood test. This test is done if you are experiencing difficulty to conceive. The test results can reveal information to know if you are ovulating or not, which helps to investigate and treat the fertility issues. Your doctor might recommend you to undergo this test if your pregnant and to rule out the threat of possible chances of ectopic pregnancy or miscarriage.
Ectopic pregnancy results when the fertilized egg attaches itself to the fallopian tubule, abdominal cavity, or cervix, rather than to your uterus. Miscarriage happens when you lose a fetus during early pregnancy as a result of low progesterone levels.
