Inhibin is a hormone that is produced by both men and women. While women have both Inhibin A and B, men only produce Inhibin B.
What is the Inhibin B test?
The inhibin B test is one of the two inhibin tests performed to detect the level of hormones in the blood.
- Inhibin B is produced by cells in the ovarian follicles.
- Inhibin B suppresses the effects of follicle-stimulating hormone (FSH) hormone. So, high levels of it are of concern.
- When the inhibin B levels are in the normal range, it indicates high chances for the woman to get pregnant.
Why is an Inhibin B test suggested?
Detecting the levels of inhibin B is important in both men and women:
- It helps to detect ovarian reserves in women and fertility in men.
- It helps to detect if a newborn child’s reproductive organs are functioning normally.
- It is useful in women with polycystic ovarian disease (PCOD) and polycystic ovarian syndrome (PCOS).
How is an Inhibin B test performed?
Using an immunoassay method, the Inhibin B test is performed in the following steps:
- The area on the forearm where the blood will be drawn is cleaned using an antiseptic.
- An elastic band is tied right above the area of the intended puncture.
- Blood is drawn from a vein using a needle and a syringe.
What are the parameters measured in the Inhibin B test?
- Low inhibin B levels indicate a lesser chance of getting pregnant.
- Low levels also mean less ovarian reserve in a few women.
- Low levels in men indicate a poor functioning of the testicles.
Preparation before performing an Inhibin B test
There is no preparation needed for an inhibin B test.
Post-care after the Inhibin B test
After an inhibin B test, no post-care measures are needed.
Sample types in the Inhibin B test
For an Inhibin B test, a blood sample is needed.
Side effects/risks of the Inhibin B test
There are no major risks involved with an inhibin B test. Some minor risks include
- Excessive bleeding.
- Infection at the puncture site.
