These tests are based primarily on antigen-antibody reactions--an antigen being a protein foreign to the body, and an antibody another type of protein manufactured by lymphocytes (a type of white blood cell) to neutralize the antigen.
Selectogen I tests for IgG antibodies to hepatitis A virus, hepatitis B virus core antigen, and hepatitis B surface antigen. Selectogen II tests for IgG antibodies to hepatitis C virus, hepatitis B core antigen, and hepatitis B surface antigen.
Hepatitis virus tests require a blood sample. It is not necessary for the patient to withhold food or fluids before any of these tests, unless requested to do so by the physician.
There are five major types of viral hepatitis. The diseases, along with the antigen-antibody tests available to aid in diagnosis, are described
Hepatitis is inflammation in the liver caused by the virus hepatitis B.
All types of hepatitis are diagnosed with a blood test.The hepatitis virus panel is a series of blood tests used to detect current or past infection by hepatitis A, hepatitis B, or hepatitis C. It can screen blood samples for more than one kind of hepatitis virus at the same time.Antibody and antigen tests can detect each of the different hepatitis viruses.Note: Hepatitis D only causes disease in people who also have hepatitis B. It is not routinely checked on a hepatitis antibody panel. http://www.std-gov.org/stds/hepatitis.htm http://www.nlm.nih.gov/medlineplus/ency/article/003558.htm
The hepatitis virus is actually named that particular virus for which it refers to. For example, the virus for hepatitis B is called the hepatitis B virus (HBV), and the virus for hepatitis C is called hepatitis C virus (HCV), and so on.
The causative agent for Hepatitis B is Hepatitis B virus.
Reference ranges for the antigen/antibody tests are as follows: hepatitis A antibody, IgM: Negative, hepatitis B core antibody: Negative, hepatitis B e antibody: Negative, hepatitis B e-antigen: Negative.
Hepatitis B is caused by the Hepatitis B virus (HBV). Hepatitis C is caused by the Hepatitis C virus (HCV). Hepatitis B virus belongs to the family Hepadnaviridae, and the genus Orthohepadnavirus. Hepatitis C virus belongs to the family Flaviviridae, and the genus Hepacivirus.
A regular Complete Blood Count (CBC) test does not specifically test for hepatitis C. The CBC measures various components of blood, such as red and white blood cells and platelets, but it does not include viral tests for hepatitis. To diagnose hepatitis C, specific blood tests that detect antibodies to the virus (anti-HCV) or the presence of the virus itself (HCV RNA) are required. If there are concerns about hepatitis C, a healthcare provider will typically order these specific tests.
Hepatitis D requires co-infection with the B type.
Hepatitis A.
