Thanks for providing this valuable service! On may 25th i (male) did unprotected oral sex on a female who worked at an asian massage parlor.  Approx 3 weeks later I developed a mild sore throat (some redness, no sores or patches).  I initially thought it was symptoms of Gerd/acid reflux (which I have barrett's esophagus) , but the started googling symptoms and became worried it could be an std.  About a week ago (4.5  weeks after exposure) I went to a lab for an oral std panel.  They used saliva which I was expecting a throat swab.  They sent it to a lab called Alimetrix, from the description of the test it was a pcr test. A week later all the following came back negative (Neisseria Gonorrhea

Chlamydia Trachomatis

Trichomonas Vaginalis

Mycoplasma Genitalium

Herpes Simplex Virus 1

Herpes Simplex Virus 2

Ureaplasma urealyticum

Treponema pallidum* (Syphilis) My question is, should I trust this test result or go get additional test? I still have the sore throat about 6 weeks later now. 

While a swab would have been preferable as a test, I would not worry that your symptoms are due to an STI and, were I you, probably would not bother additional testing although the decision to test is certainly a personal one.  If you do re-test, please have the samples be taken with a swab (the syphilis test, should be a blood test)   EWH

From your reply, I understand that the saliva test I took is not as accurate as a swab.  I couldn't find any specific information on the accuracy of saliva tests on gonorrhea (I think this is my main risk factor from reading here).

On an unrelated note, I had some recent bloodwork done and my wbc was normal.  If I had a throat infection Std would this typically be elevated with sore throat symptoms? 

As I said before, "were I you, probably would not bother additional testing although the decision to test is certainly a personal one".  EWH
