Know More About This Test
Inhibin A is a hormone produced mainly by the ovaries and placenta. It plays a role in regulating follicle-stimulating hormone (FSH). This test is commonly used in prenatal screening and female fertility evaluation. It is also used in monitoring certain ovarian tumors.
Why Is This Test Recommended?
Inhibin A testing is recommended for prenatal screening during the second trimester (quad screen), fertility assessment, monitoring ovarian tumors, and evaluating menstrual irregularities. Abnormal levels during pregnancy may indicate chromosomal abnormalities. In non-pregnant women, it reflects ovarian function.
What Do the Results Indicate?
High levels in pregnancy are typically normal. Abnormal levels need correlation with other markers for accurate interpretation. Results help assess fetal development, ovarian function, or potential ovarian pathology.
How Is the Test Performed and Prepared For?
Blood sample is collected. No fasting is required. Inform your doctor of pregnancy status.
