I just came to find out on a routine general check that my HBVsAg is positive and I have only done ultrasound and HBV dna pcr test. How can I know when I got infected? The doctor told me to follow up after six month with the same tests and I don’t have to take any medication.
Great question and welcome to the forum.
If you were exposed recently (within the last few months) then you would be anti-HBc IgM antibody positive. Otherwise there is no real test of when you were infected.
Your very low HBV DNA levels (PCR results) are a great sign and have been linked to good prognosis and low levels of liver disease progression. 6-monthly monitoring, as suggested by your doctor, is the standard recommended practice and is important to make sure any changes in your condition are picked up.
Hope this helps,
So you mean I am chronically infected?
Chronic infection is defined as being HBsAg-positive for more than 6 months, so I am unable to tell using only the test results you have shared.
Okay so how can I reduce my viral load to be undetectable without medication
There are no consistent methods known to reduce viral loads to undetectable without medication.
