Hi self medicating is probably not a good idea. But you panicked over a low risk situation. Antibiotics do not mask the test. Either they cure the infection or not. And the gonorrhea test and chlamydia test were done 3 weeks post exposure. So you should be fine. Taka care!
Antibiotics don't even mask URINE tests? This wasn't a swab.
Also....can I assume that the 1g Rocephin my wife received at the hospital took care of any potential gonorrhea or Chlamydia she may have had?
The urine tests were: "This test was performed using the APTIMA COMBO2 Assay".
Copied and pasted right from the lab result.
Your test 3 weeks post exposure is more than enough. You should be fine
