Hormone Inhibin A

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• If you smoke. This increases the level of inhibin A in the blood.
• If you are obese. This decreases the level of inhibin A in the blood.

The results of the quad screen, including inhibin A, are based on a woman's age, race, weight, and whether she is diabetic.
