Hepatitis B is now very common and highly contagious. To accurately diagnose the course and extent of hepatitis B, it is necessary to have HBeAg and HBeAb tests.1. HBeAb . test
HBeAb is a test to assess whether a patient infected with hepatitis B has viral activity if HBeAg Hepatitis B) is positive, on the other hand, also evaluate seroconversion after a period of hepatitis B treatment. If HBeAb is negative before, HBeAb positive after treatment indicates seroconversion.HBeAb seroconversion occurs when HBeAb changes from (–) to (+) and HBeAg from (+) to (–). This phenomenon reflects the reduction or cessation of viral replication. HBeAb seroconversion can occur spontaneously (approximately 10%-15% per year) or seroconversion is accelerated by antiretroviral therapy.
However, some patients have had HBeAb seroconversion but HBeAg may re-emerge during episodes of hepatitis B reactivation. This phenomenon can occur in men who are homosexual, or receive chemotherapy for cancer, or receive corticosteroids.
In chronic hepatitis B, the presence of HBeAb indicates that the disease has progressed for a relatively long time, especially if it has progressed to cirrhosis, or primary liver cancer.
To understand their disease status as well as monitor the progress of the disease, patients should check their liver status and do tests to check the activity of the virus every 3 to 6 months, re-examination. periodically to see if medication is needed to treat it, to avoid serious illness that can cause bad complications.
The HBeAb test is important for early identification of potentially serious liver complications

Specimen is stable for 5 days, stored at 2 - 8°C, for 3 months at -20°C.
Specimens are thawed only once and must be allowed to reach room temperature before analysis. To avoid evaporation, samples, standards, and quality control substances should be analyzed within 2 hours.
3. Carrying out the technique
The analyzer needs to be ready to perform sample analysis: The meter has been calibrated with the Anti-HBe test, the quality check results with the successful Anti-HBe test are not out of range and do not violate quality control violations.Staff performing sample analysis enter data about patient information and order tests into the analyzer or network system. Load the specimen into the analyzer. Instruct the machine to perform the analysis of the patient sample. Wait for the analyzer to analyze the sample according to its protocol. When the results are available, it is necessary to review and evaluate the results, then print the test results sheet to return to the patient.
4. What does the HBeAb . test mean?
