Recently I did my blood test after my 3 months exposure and it came back negative except for gonorrhea because my doctor told me that there is no test for this particular std..however i did a wisdom tooth surgery twice, one is 3 weeks and the other one is 1 week before i went for my blood test. will this surgery affect my test results? Plus on top of that my dentist prescribed me with medicine like painkillers, antibiotic and anti swelling pills and a liquid medicine to wash my mouth...I am sorry but i cannot seem to remember the actual drug name and i only describe base on their purpose.
