  • Hepatitis B Virus (HBV) test 5
  • Syphilis test 5
  • Blood pressure monitoring 5
  • Urine protein and urine glucose testing 5

Purpose of Tests

These tests are performed to:

  • Identify potential risks and complications early on 2
  • Prevent pregnancy complications and predict neonatal and infant medical issues 2
  • Ensure the health and well-being of both the mother and the fetus 3
  • Guide policies targeted at addressing pregnancy-induced health challenges 5
