HCG: A hormone produced by the placenta.

Estriol: The placenta and the baby’s a hormone produced by the liver.

Inhibin A: Another hormone produced by the placenta.

If inhibin is not measured and the other three substances are measured, the name of the test is called triple screen test . Quadruple screening test results are more reliable than triple test values ​​. The quadruple screening test increases the sensitivity of detecting down syndrome by 20%.
