How Dr. Rishi Chadha Diagnoses Hepatitis B?

Blood Tests

  • Hepatitis B surface antigen (HBsAg): confirms active infection
  • Hepatitis B surface antibody (anti-HBs): shows immunity status
  • Liver enzyme tests (ALT, AST): assess liver inflammation
  • Viral load test: measures amount of virus in the blood

Imaging Tests

  • Ultrasound: evaluates liver structure and detects scarring
  • FibroScan-: painless elastography to measure liver stiffness
