There are different types of hepatitis virus infections depending on the exposure and the severity. Hepatitis can be highly infectious. If the patient has contacted hepatitis, he or she may be spreading the disease among the people around him or her, aside from the fact that the symptoms can become life-threatening pretty fast. Before the virus is spread further, it is important that a hepatitis test is conducted at the earliest possible. The doctor can suggest which hepatitis test is needed, because there are multiple tests for multiple types of hepatitis viruses.
