If you searched and read other threads as I suggested, you have seen that although
results above 1.1 are officially considered positive. However, only
results above 3.5 are definitely positive. Your results of 1.22 and 1.54 were very low and most likely truly negative; the value of 2.44 is of greater concern. Still, with these mixed results, and your negative sexual history, most likely you are not infected.
There are confirmatory tests that can sort this out.
