Testing Algorithm

If the hepatitis C virus (HCV) antibody result is reactive, then HCV RNA detection and quantification by real-time reverse transcription-polymerase chain reaction will be performed at an additional charge.

Interpretation

Interpretation depends on clinical setting. See Viral Hepatitis Serologic Profiles

 

Hepatitis A Virus (HAV):

HAV-specific antibodies are usually detectable by the onset of symptoms (usually 15 to 45 days after exposure). The initial antibody consists almost entirely of IgM subclass antibody. Anti-HAV IgM usually falls to undetectable levels 3 to 6 months after infection.

 

Hepatitis B Virus (HBV):

HBsAg is the first serologic marker appearing in the serum 6 to 8 weeks following HBV infection. In acute cases, HBsAg usually disappears 1 to 2 months after the onset of symptoms. Anti-HBs appears with the resolution of HBV infection after the disappearance of HBsAg. Anti-HBs also appear as the immune response following a course of inoculation with the hepatitis B vaccine.

 

During acute hepatitis B in symptomatic individuals, detectable anti-HBc consists almost entirely of the IgM subclass. Anti-HBc IgM can be detected shortly after the onset of symptoms and usually remains detectable for 6 months. Anti-HBc IgM and Anti-HBc total may be the only serologic markers of a recent HBV infection detectable in the "window period", during which HBsAg has declined to become undetectable and anti-HBs has not yet become detectable.

 

Hepatitis C Virus (HCV):

In immunocompetent individuals, HCV-specific IgG and IgM antibodies are usually not detectable in the first 2 months after exposure to HCV, and this "window period: may be as long as 6 months in immunocompromised individuals. HCV antibodies are not neutralizing and does not provide immunity against subsequent HCV infection.

 

If HBsAg, anti-HAV IgM, and anti-HCV are negative and patient's condition warrants, consider testing for Epstein-Barr virus or cytomegalovirus.

Clinical Information

Hepatitis A:

Hepatitis A virus (HAV) is an RNA virus that accounts for 20% to 25% of acute viral hepatitis in adults in the United States. Hepatitis A is spread by the oral/fecal route and produces acute hepatitis, which follows a benign, self-limited course. Spread of the disease is usually associated with contaminated food or water caused by poor sanitary conditions. Outbreaks frequently occur in overcrowded situations and institutions or high-density centers such as prisons and healthcare centers. Epidemics may occur following floods or other disaster situations. Chronic carriers of HAV have never been observed.

 

Hepatitis B:

Hepatitis B virus (HBV) is an endemic DNA virus throughout the world. The infection is spread primarily through percutaneous contact with infected blood products (eg, blood transfusion, sharing of needles among injection drug users). The virus is also found in virtually every human body fluid and is known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions; it is not commonly transmitted transplacentally. After a course of acute illness, HBV persists in approximately 10% of patients. Some chronic carriers are asymptomatic; others develop chronic liver disease, including cirrhosis and hepatocellular carcinoma.

 

Hepatitis C:

Hepatitis C virus (HCV) is an RNA virus that is a significant cause of morbidity and mortality worldwide. The infection is transmitted through contaminated blood or blood products or other close, personal contacts. It is recognized as the cause of most cases of posttransfusion hepatitis. Hepatitis C shows a high rate of progression (~75%) to chronic infection and disease and accounts for the majority of chronic viral hepatitis In the United States. Cirrhosis and hepatocellular carcinoma are sequelae of chronic infection with this virus.
