1900 1034 Hepatitis A virus (HAV) is one of the most common causes of liver inflammation. When first infected with HAV, your immune system produces IgM antibodies, which appear in your blood 5 to 10 days before symptoms appear. They can stay in your blood for about six months after infection, with IgG antibodies remaining for life.
Hepatitis A virus is one of the most common causes of liver inflammation. Your immune system makes antibodies when you are first infected with HAV. IgM Antibodies often begin to appear in the blood 5 to 10 days before symptoms appear. They can stay in your blood for about six months after the infection. Some antibodies called IgG can last in your blood for life.
Hepatitis A is commonly spread by eating or drinking contaminated food or water. This may happen if an infected person doesn't wash their hands after using the bathroom. Most people recover from hepatitis A without lasting liver damage. This test detects the presence of HAV antibodies, which indicate prior or acute infection with, or immunization to, the hepatitis A virus.
The Hepatitis B virus (HBV) is a common cause of liver inflammation. Your immune system makes IgM antibodies against HBV that appear in your blood several weeks after infection. People with the hepatitis B vaccine will not have this antibody in their blood. The test determines whether you are actively infected with the hepatitis B virus (HBV).
The quantitative test of hepatitis B core antibody level distinguishes cases of hepatitis antibodies from vaccination with those with a history of cured acute hepatitis B. This test can also be used with other hepatitis immunological indicators to evaluate treatment effectiveness in hepatitis B patients.
The hepatitis B virus (HBV) is one of the major causes of liver inflammation. The hepatitis B e antigen (HBeAg) appears after an HBV infection. Usually, HBeAg indicates much higher rates of viral replication and enhanced infectivity. However, variants of the hepatitis B virus do not produce the 'e' antigen, so this rule does not always hold. The HBeAg may be cleared, and antibodies to the 'e' antigen (anti-HBe) will arise immediately afterward, suggesting a dramatic decline in viral replication.
This is a viral protein made by the hepatitis B virus that is released from infected liver cells into the blood. A positive HBeAg indicates high virus levels in the blood, with the person considered infectious. A negative result indicates very low to no virus in the blood, and the person is considered less infectious; sometimes, this can indicate a person has a mutant hepatitis B virus.
HBsAb test, also known as the Hepatitis B surface antibody test, looks for antibodies against the Hepatitis B virus in the blood. This test helps figure out if there's immunity to Hepatitis B, either from getting vaccinated or from a past infection. When the body makes antibodies, it means it's responded to the virus in some way, giving protection against future infections. This test is especially useful for telling if the Hepatitis B vaccine worked or if there was an infection and developed immunity. Getting this test done is simple - it just needs a small blood sample. Knowing the status of Hepatitis B antibodies can be really important in staying on top of health and stopping the spread of this virus that affects the liver.
Hepatitis B surface antigen (HBsAg) is a crucial protein that resides on the surface of the Hepatitis B virus (HBV), serving as a marker that enables our immune system to identify and combat the virus. The qualitative HBsAg test, a blood test, is employed to ascertain the presence of this antigen. A positive test result indicates an ongoing Hepatitis B infection, while a negative result suggests the absence of current infection. This test holds immense significance due to the potential of untreated Hepatitis B to cause severe liver damage. Early detection through the qualitative HBsAg test allows healthcare professionals to promptly initiate treatment if necessary, thereby averting the progression of the infection and minimizing the risk of liver-related complications.
Hepatitis B is a liver inflammation caused by the type B virus and is one of the most common causes of cirrhosis in Viet Nam. Hepatitis B surface antigen (HBsAg) is a protein that appears in the blood when you have a hepatitis B infection.
HBV-DNA or hepatitis B virus DNA is a measure of the viral load of the hepatitis B virus in the blood. A high HBV-DNA level indicates that the virus is multiplying in the individual’s body and the person is contagious. The test is most often used to monitor the efficacy of antiviral therapy in individuals with chronic HBV infection.

The HCV Ab test, or Hepatitis C antibody test, is a simple blood test that checks for past infection with the Hepatitis C virus. This virus primarily targets the liver, potentially causing various levels of liver damage. The test searches for antibodies to the Hepatitis C virus, which are substances the body produces in reaction to being infected. A positive result doesn't necessarily mean the virus is currently present, but rather that there has been exposure at some point. Further testing, like a viral load test, would be required to determine if the infection is current. The Hepatitis C antibody test is often included in regular medical screenings, especially if there is a higher risk for Hepatitis C or indications of liver issues.
