Inhibin A Maternal Marker Test Cost & Procedure

An inhibitor The level of this hormone in a pregnant woman's blood is measured in a test to determine whether the unborn child might have Down syndrome. During pregnancy, the placenta produces inhibin A. A maternal serum quadruple screening test uses the blood's inhibin A concentration to determine the results.

Inhibin: A Down syndrome marker?

A second-trimester maternal blood marker for fetal Down's syndrome (DS) is inhibin A. We looked into the feasibility of using inhibin A early in the first trimester. Inhibin A maternal blood concentrations were assessed in 81 healthy controls and 27 fetal trisomy 21 cases between weeks 5 to 11 of pregnancy.

What is the inhibin A range for a pregnancy of 19 weeks?

At 15-19 weeks and 21-25 weeks, respectively, there were 65 (92%) and 64 (90%) samples in the pre-eclampsia group, and 232 (95%) and 227 (93%) samples in the controls. Inhibin A's normal range was 41.4-690 pg/ml at 15-19 weeks and 47.6-1719 pg/ml at 21-25 weeks.

Why do pregnant women have high inhibin A levels?

Inhibin A levels > 2.0 MOM enhance the risk of preterm birth and SGA in non-smoking pregnant women. This danger increases.

Why is the marker inhibin used?

For mucinous and granulosa ovarian cell tumors, CA 125 is not a very reliable tumor marker. With those 2 types of ovarian cancer, inhibin performs better.

What function does inhibin A serve during pregnancy?

Traditionally, inhibin has been observed to suppress pituitary follicle-stimulating hormone release. Throughout pregnancy, the fetoplacental unit releases inhibition.
