What is the purpose of serum and urine tests during pregnancy?

• A. Assess fetal well-being
• B. Verify presence of human chorionic gonadotropin (hCG)
• C. Measure maternal blood sugar levels
• D. Check for dehydration

Answer: (B)

The purpose of serum and urine tests during pregnancy primarily includes the verification of the presence of human chorionic gonadotropin (hCG). hCG is a hormone produced by the placenta shortly after the embryo attaches to the uterine lining. The presence of this hormone in the blood or urine is one of the earliest indicators of pregnancy, often detected within a few weeks after conception. Testing for hCG levels is crucial not only for confirming pregnancy but also for monitoring the health and progression of the pregnancy in its early stages.

While other options present important aspects of prenatal care, they do not specifically align with the primary function of serum and urine tests during pregnancy. Assessing fetal well-being can be done through other methods, such as ultrasound or fetal heart rate monitoring. Measuring maternal blood sugar levels is typically facilitated through blood tests designed to assess conditions like gestational diabetes. Checking for dehydration is usually evaluated through different clinical assessments rather than specifically through serum or urine tests aimed at confirming pregnancy.
