Which of the following is TRUE of pregnancy tests?

Question

Quizplus · Accepted Answer

The most common pregnancy test is based on detecting hCG (human chorionic gonadotropin) in a woman's urine, which is a hormone present after implantation of a fertilized egg in the uterus.

Option B is incorrect because early in the pregnancy, hCG levels are generally low and may not be detected, but as the pregnancy progresses, levels of hCG increase, making it easier to detect pregnancy even in laboratory tests.

Option C is incorrect because laboratory tests generally have higher sensitivity in detecting pregnancy and produce fewer false negatives than home pregnancy tests.

Option D is incorrect because over-the-counter pregnancy tests are designed to detect hCG in urine, which is present in healthy pregnancies, not ectopic pregnancies, which occur when a fertilized egg implants outside the uterus.
