I'm sorry... but I do not understand that... what is ASO? I don't know what the 3 is supposed to mean. If you can type out (exactly) the name of the test, the reference ranges, and the reported information, maybe I'll understand better.
before i received two doses of vaccination then i checked my ASO titre but the result is less than three. i want to ask if what is the risk if the ASO titer is less than normal values?
