Answer the questions below -
1. Was there any exposure that you can think of?
2. If Yes, when was this test taken post exposure?
3. Were these tests taken under the supervision of an expert?
What Vance said, you need to get a "STANDARD" ELISA test, no oral swab / Rapid, if it comes back positive, you would need to follow it up with a WB. Please consult an infectious disease doctor (HIV specialist) and follow the advise he / she suggests you.
Good Luck
Have a standars ELISA test and if posiitve then the WB will need to be done again.
It is mean you should test again,how long after exposure you tested,
