Introduction
Table of Contents
Viral hepatitis refers to a group of infectious diseases caused by different types of hepatitis viruses, including hepatitis A, B, C, D, and E. These viruses can cause inflammation and damage to the liver, leading to a range of symptoms from mild to severe. Some forms of this hepatitis can also lead to chronic liver disease, liver cancer, and even death.
Test Result and Test Methods
The results of viral hepatitis tests can provide information about whether a person has be exposed to or infected with a specific type of hepatitis virus. Hepatitis A and E are acute infections, and people usually recover completely without long-term liver damage. Hepatitis B, C, and D, on the other hand, can cause chronic infections, and the results of tests for these viruses can help determine the severity of the infection and guide treatment decisions.
The most common tests used to diagnose this infection include blood tests to detect viral antigens, antibodies, or genetic material (RNA or DNA) of the virus. Depending on the type of viral hepatitis suspected, specific tests may be ordered. For example, the hepatitis B surface antigen (HBsAg) test is used to detect current or chronic infection with hepatitis B, while the hepatitis C antibody test is used to detect past or current infection with hepatitis C. Other tests may be used to assess the severity of liver damage or the risk of liver cancer in people with chronic hepatitis.
