Does hep b titer tell if you were previously infected? Vaccinated as child. Result showed 11miu/ml. 10miu is min. Is mine low & should I be concerned?

In brief: Probably not

If you were vaccinated as a child and still have detectable antibodies left from that vaccine, chances are good that your vaccine ( it should have been a series of three doses) has protected you all this time and is still protecting you.
More tests would be required to try to learn if you were ever infected, or are currently infected. The titer only says you have made a response to vaccine or bug.

In brief: Ask the ordering Dr.

There are a whole bunch of hepatitis b titers, and the meanings of each vary depending on a person's situation and past titers.
The only way to be sure is to ask the dr. Who ordered the test(s). If a person at low risk for hepb, was vaccinated at birth, and got a titer done, it usually is the hepbsab to see if he needs booster shots. If his titer is low or close to low, he can get booster shots.
