Chlamydia will not throw off your igg test results. It is possible that the 2.44 is a false positive. Anything less than a 3.5 needs confirmation testing. The most accurate test for hsv1 is the western blot from the University of Washington.
It could be a false positive or the test missed the infection on your previous test.
Igg tests miss at least one out of ten hsv1 infections.
You can contact the university of Washington and they will ship you the kit. Then you have a Dr draw the blood and ship it back to them.
Igg blood tests look for antibodies the body produces when hsv is present. Not the actual virus. Some times the test sees another odd protiens and triggers a low positive response. The higher the numeric value of the test the more confident the test is it saw the antibodies. Like I said, anything under a 3.5 needs confirmation. You can take another igg test and see or get the western blot.
