The test is performed to identify the concentration of antibodies against the hepatitis B virus. Understanding how the anti-HBs test works
What is the anti-HBs test for?
The anti-HBs test is used to identify the amount of antibodies a person has in the blood against HBs Hepatitis Ba disease caused by a virus that causes inflammation of the liver. According to Sheila Pinto, a pharmacist at Badim Hospital, the exam is generally indicated for patients who have received treatment for the disease or after vaccination.
A person infected with the virus hepatitis B has some viral markers that can be identified by analyzing blood. Virus surface antigen (AgHBs) is a marker of infection and the presence of antibodies against this antigen (anti-HBs) indicates protection against the disease.
How does the anti-HBs test work?
According to Sheila, there is no need to fast or do any kind of preparation before the exam. The laboratory professional collects a blood sample from the patient, which will undergo a serological analysis process.
If the result shows the presence of anti-HBs, the test should be repeated. “After 30 and 60 days, it is recommended to perform a new test in case of positive anti-HBs. The reason is that, due to infection with different subtypes of the hepatitis virus or the formation of immune complexes (or antibody complex -antigen ), the test may indicate a false positive result”, explains the pharmacist.
