Welcome to the Forum. There is not a need to wait 3 months to test for most STDs. Testing for gonorrhea, chlamydia and NGU can be performed 3 days after exposure. Syphilis testing is definitive at 3 months, as is testing for hepatitis B. In both cases the infections are quite rare and results as early as 6-8 weeks are highly, but not perfectly reliable. For HIV, testing at 8 weeks gives reliable results. In the absence of lesions, we do not recommend blood tests for HSV as the likelihood of a falsely positive test result is probably higher than the likelihood of infection.
As for the exposures you describe, few STDs are spread by either giving or receiving oral sex an HIV is not one of them.
I hope these comments are helpful. EWH
Thank you for your response. I did not know that you can get accurate results for HIV at 8 weeks. I have heard conflicting information regarding this (I have been told you have to wait 3-6 months for 100% accurate testing). So if all my test results were negative, I should have no worries? Sorry, just trying to put my mind at ease...
We get many questions about the meaning of HIV test results at different time points. This is now confused by the availability of a variety of different types of tests. The traditional and most widely used tests for HIV are tests for antibodies to HIV which are available both as so-called "rapid" or point of care tests which can be done in the clinic and laboratory based antibody tests. For all practical purposes both of these types of test perform comparably and provide accurate information on the presence or absence of HIV infection in virtually everyone at 8 weeks following exposure. The recommendations for testing at 3 and even 6 months are the result of two factors- data from older tests no longer used (you really do not need to worry about which generation of tests you were tested with, at this time virtually all tests are far more sensitive that they were even 2-3 years ago when the 3 month recommendation was made) and secondly, the fact that some, mostly governmental agencies which have to provide recommendations for virtually everyone without the sort of interactions such as those you get with your doctor or on personalized sites such as this one, feel the cannot "afford" to be wrong and therefore make recommendations and guidelines which leave most people unnecessarily nervous for 4-6 weeks longer than the 6-8 weeks it takes virtually everyone to develop HIV antibodies. I hope this clarifies things. EWH
