I need to answer a medical MCQ about the quadruple test for Down syndrome in the second trimester. The components include AFP, unconjugated estriol, beta-hCG, and inhibin A—not inhibin B. Thus, when looking at the options, the correct answer is D, inhibin B, since it's not part of the test. I’ll make sure to clarify these terms and confirm my answer succinctly with proper references.
