Overview Brief

Hormone Inhibin is associated with reproduction and it has two types: Inhibin A and Inhibin B. Females have both inhibin types but males have only inhibin B. [1]

What is an Inhibin A test?

The Inhibin A test measures the levels of the hormone in your blood.

  • In women, Inhibin A is secreted by the main follicles and inhibin B by the smaller ones. [1]
  • In men, inhibin B is produced by the testicles.
  • Levels of Inhibin help understand the functioning of the reproductive organs in women.

Inhibin A is part of the quad test done to detect the risk of abnormalities in a fetus.

Why is an Inhibin A test suggested?

The Inhibin A test is suggested in the following cases:

  • When a woman’s ovaries are not functioning properly.[2]
  • During pregnancy to detect if all is well with the baby.
  • Increased levels of Inhibin A indicate ovarian cancers, granulosa cell, and other epithelial cell tumors.[1]

How is an Inhibin A performed?

The Inhibin A test is done using an immunoassay method.

  • The area on the forearm where blood will be drawn from is cleaned using an antiseptic.
  • An elastic band is tied right above the area of intended puncture.
  • Blood is drawn from a vein using a needle and syringe.

The collected blood is sent for detecting the amount of Inhibin A.

What are the parameters measured in the Inhibin A test?

The inhibin A levels in the blood are important because high levels indicate:

  • Serious abnormality in the fetus when done in a quad test.
  • Down’s syndrome when done in the second trimester.
