- Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus.uman hepatitis B virus (figure 3) is the prototype virus of the hepadnavirus family and causes serum hepatitis. HBV has a diameter of about 40nm. It infects humans and chimpanzees but there are closely related members of this family that infect other mammals and birds. HBV is a DNA virus and is enveloped.

Hep B Titer- (Hep B Surface, antibody) Quantitative This assay is used to determine immune status for Hepatitis B. Hepatitis B Surface Antibody (HBsAb or anti-HBs): The “surface antibody“ is formed in response to the hepatitis B virus. Your body can make this antibody if you have been vaccinated, or if you have recovered from a hepatitis B infection. If this test is positive, then your immune system has successfully developed a protective antibody against the hepatitis B virus. This will provide long-term protection against future hepatitis B infection. Someone who is surface antibody positive is not infected, and cannot pass the virus on to others. This is a Quantitative test required by many schools and medical programs ...

Hepatitis and Sex: Frequently Asked Questions Hepatitis B (HBV) is 50 to 100 times easier to transmit sexually than HIV (the virus that causes AIDS). HBV has been found in vaginal secretions, saliva, and semen. Oral sex and especially anal sex, whether it occurs in a heterosexual or homosexual context, are possible ways of transmitting the virus.

National Leader in Affordable Direct to Consumer Lab Testing Specimen Type: Blood. Description: This test is used to look for the presence of Hepatitis B (Hep B) viral genetic material in the blood. The results for this test are quantitative, meaning they provide a numerical result rather than a simple positive or negative.esults for this test are quantitative. People who require a Hep B PCR test but only desire a positive or negative result may order the Hepatitis B PCR Qualitative test.

Hepatitis B - Get the Facts Hepatitis B is a liver disease caused by the hepatitis B virus (. ). HBV is far more infectious than HIV and can be prevented by a vaccine. People who have not been vaccinated may be at risk of getting infected.About 95 percent of adults will recover within 6 months of becoming infected (acute hepatitis B) and as a result will develop lifelong protection against it.BV is far more infectious than HIV and can be prevented by a vaccine.

RNA virus RNA viruses can be further classified according to the sense or polarity of their RNA into negative-sense and positive-sense, or ambisense RNA viruses. Positive-sense viral RNA is similar to mRNA and thus can be immediately translated by the host cell.his nucleic acid is usually single-stranded RNA (ssRNA) but may be double-stranded RNA (dsRNA). Notable human diseases caused by RNA viruses include Ebola hemorrhoragic fever, SARS, influenza, hepatitis C, West Nile fever, polio, and measles.

Background Hepatitis D virus (HDV) is an RNA virus that is structurally unrelated to hepatitis A (HAV), hepatitis B (HBV), or hepatitis C virus (HCV). It was discovered in 1977. HDV causes a unique infection that requires the assistance of viral particles from HBV to replicate and infect other hepatocytes.Its clinical course is varied and ranges from acute, self-limited infection to acute, fulminant liver failure.

Hepatitis B Hepatitis B is an infectious liver disease. It is caused by the hepatitis B virus (HBV). Infections of hepatitis B occur only if the virus is able to enter the blood stream and reach the liver.Once in the liver, the virus reproduces and releases large numbers of new viruses into the bloodstream. To combat the disease, the body has several defenses.nfections of hepatitis B occur only if the virus is able to enter the blood stream and reach the liver.

What Is Hepatitis B? The hepatitis B virus contains an outer envelope and an inner core. 1  The outer envelope of the virus is composed of a surface protein called the hepatitis B surface antigen or HBsAg. The HBsAg can be detected by a simple blood test and a positive test result indicates a person is infected with the hepatitis B virus.

Hepatitis B virus Hepatitis B virus, abbreviated HBV, is a species of the genus Orthohepadnavirus, which is likewise a part of the Hepadnaviridae family of viruses. This virus causes the disease hepatitis B.he early evolution of the Hepatitis B, like that of all viruses, is difficult to establish. The divergence of orthohepadnavirus and avihepadnavirus occurred ~125,000 years ago (95% interval 78,297–313,500). Both the Avihepadnavirus and Orthohepadna viruses began to diversify about 25,000 years ago.
