More Details

What is the purpose of this test?

This comprehensive screening panel evaluates maternal health and identifies conditions that could affect pregnancy outcomes (CDC 2025). The test combines essential markers including complete blood count, blood type compatibility, and infectious disease screening. Most critically, it detects hepatitis B surface antigen, which poses a 90% transmission risk to newborns without proper intervention (University of Washington 2025).

Who would benefit from this test?

All pregnant women should receive this screening, as recommended by the U.S. Preventive Services Task Force (USPSTF 2019). This includes women of all ages and risk levels, as hepatitis B can be asymptomatic. Direct-to-consumer testing particularly benefits uninsured patients, with studies showing average savings of $369 compared to hospital outpatient charges (PMC 2024).

When should I order the Prenatal Profile (OB) Blood Test with Hepatitis B Surface Antigen?
Order during early pregnancy, ideally in the first trimester, to enable timely interventions (CDC 2025). Early detection allows for proper case management and specialized care coordination. The American College of Obstetricians and Gynecologists emphasizes first-trimester screening as standard prenatal care (ACOG 2024).

How do I interpret the results?

Hepatitis B Surface Antigen

  • Result: Negative – No current infection detected
  • Result: Positive – Immediate medical follow-up required

CBC Values (Complete Blood Count)

  • Result: Normal ranges – Continue routine prenatal care
  • Result: Abnormal – Monitor for anemia or infection

Blood Type/Rh

  • Result: Compatible – Standard pregnancy management
  • Result: Incompatible – Special monitoring protocols

Hepatitis B testing demonstrates 94.1% sensitivity and 98.2% specificity using immunochemiluminometric assay methodology.

Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.

Pre-test preparation

No fasting is required for this comprehensive blood panel. However, discontinue biotin supplements at least 72 hours before collection to prevent test interference (LabCorp 2025). Inform your healthcare provider about any medications or supplements you're taking. Schedule the test early in pregnancy for optimal timing.

How often should I get tested?

  • Standard pregnancy: Once in the first trimester
  • High-risk pregnancy: As directed by healthcare provider
  • Positive hepatitis B: Regular monitoring throughout pregnancy
  • Planning future pregnancy: Before conception for each pregnancy

Why early detection matters

Early identification enables life-saving interventions for both mother and baby. Proper immunoprophylaxis with hepatitis B vaccine and HBIG prevents mother-to-child transmission in over 90% of cases when administered correctly (Hepatitis B Foundation 2025). Global hepatitis B prevalence in pregnant women ranges from 3.15% to 8%, making screening essential regardless of perceived risk factors.
