Hepatitis Be Antigen Blood Test
What is Hepatitis Be Antigen?
This test is used in the diagnosis and monitoring of Hepatitis B (Hep B) infections. The Be Antigen test looks for the presence of a protein found in the blood when the Hep B virus is actively replicating. During these periods, a person is considered to be highly infectious and at a higher risk for spreading the virus to others. Pregnant women have a much greater risk of spreading the virus to their infants during birth when the Hep B virus is replicating. This state usually occurs 3-6 weeks after infection.
Hepatitis B is a viral liver infection that is spread through exposure to infected blood or bodily fluids. It is the most common cause of acute viral Hepatitis. Hepatitis B infections often show no symptoms, but when symptoms do occur, they are often described as flu-like. Common symptoms include abdominal pain, fever, loss of appetite, nausea, joint pain, fatigue, jaundice, and dark colored urine. Chronic Hep B infections can cause serious health complications like Cirrhosis and Liver Cancer.
What is the purpose of a Hepatitis Be Antigen Test?
The Hepatitis Be Antigen test can be used to screen for Hep B. However, it is not effective at detecting the virus during a latent period when it is not actively replicating. The Hepatitis B Surface Antigen Test or the Hepatitis B Panel is more commonly ordered as a screening because it can detect both recent and chronic infections. The Be Antigen test is often ordered by people who are receiving treatment for Hepatitis B because it can help to determine if they have been effective in halting the replication of the virus.
How long does a Hepatitis Be Antigen Test take?
Turnaround time for the Hepatitis Be Antigen test is typically 1-2 business days.
