Neonatal Hepatitis B Virus (HBV) Infection
Diagnosis of Neonatal HBV Infection
Serologic testing Diagnosis of neonatal HBV infection is by Diagnosis , including measurement of HBsAg, HBeAg, antibody to hepatitis B e antigen (anti-HBe), and quantitation of HBV DNA in blood. Other initial tests include complete blood count (CBC) with platelets, alanine aminotransferase (ALT) and alpha-fetoprotein levels, and liver ultrasonography. Family history of liver cancer or liver disease is noted because of the long-term risk of hepatocellular carcinoma. If testing suggests HBV infection, consultation with a pediatric hepatologist is recommended.
