HBV DNA Result Detectable or Not Detectable?

Question

Hello, Dr. Holodniy:

Diagnosed two years ago as Inactive Hep B Carrier. Yesterday, got my lab results, and my doctor seems very pleased.

I've never really understood what the test results mean (very complicated Virus to understand). But, my question now is what do my current test results mean? Do I have Virus in my blood or not?

My HBV DNA result is as follows:

Component Your Value Standard Range HEPATITIS B VIRAL DNA, IU/ML <100.00 <100- IU/mL

HEPATITIS B VIRAL DNA, COPIES/ML <160 <160 *- copies/mL

Component Your Value Standard Range HEPATITIS B E AG NONREACTIVE NONREACTIVE-

Curious as to how I can still be infectious if I don't have virus in my blood? Or is the concern more that I could become infectious if the virus were to reactivate?

All of my liver function tests are well within normal limits, including Kidney function.

Thanks for your help, Doctor.

Answer

You don't indicate what previous tests or results were obtained to indicate that you had been a carrier. It is hard to interpret that status from the lab tests presented. If the surface antigen is positive than you are still likely to be a carrier and potentially infectious.
