What routine prenatal laboratory test screens for syphilis?

• A. HIV test
• B. RPR (Rapid Plasma Reagin)
• C. Blood type and Rh factor
• D. Amniocentesis

Answer: (B)

The Rapid Plasma Reagin (RPR) test is a non-treponemal blood test primarily used for screening syphilis during routine prenatal care. This test detects antibodies produced in response to the syphilis infection. Early detection of syphilis is crucial as it can prevent serious complications for both the mother and the fetus, including congenital syphilis, which can lead to severe health issues for the newborn. Prenatal guidelines recommend that all pregnant individuals be screened for syphilis early in pregnancy and again in the third trimester if they are at high risk. The RPR test is favored due to its simplicity, rapid results, and effectiveness at identifying syphilis infections before they cause significant harm. While the other options listed are important components of prenatal care, they serve different purposes. The HIV test screens for human immunodeficiency virus, while blood typing and Rh factor testing determine the mother's blood type and Rh compatibility with the fetus. Amniocentesis is a diagnostic procedure used primarily for genetic testing and assessing fetal health, but it is not a routine screening for syphilis.
