Which of the following is NOT TRUE about the Alpha Fetoprotein (AFP) screening test?
  1. It can diagnose spinal tube defects.
  2. It is typically done between 15 and 18 weeks of pregnancy.
  3. It has a high rate of false-positive results.
  4. It may also be referred to as a "triple screen" or "quad screen"
Explanation
Answer: A - While the AFP test can screen for neural tube defects, it cannot definitively diagnose them. The AFP, sometimes called a "triple" or "quadscreen", is a blood test done during the second trimester at about 15 to 18 weeks. A positive AFP may lead to additional testing, such as amniocentesis. Because the test has a high rate of false-positive results, its routine use is controversial. Pregnant women can make an informed decision by getting the pros and cons before consenting to the test. It is not a necessary part of pregnancy care.
