Could hiv show up in the saliva before blood?could hep c cause a false positive result for a antibody hiv test?

ok i went to a free clinic to get a rapid hiv saliva test done and it came back non reactive.a month later i went again with my partner just so we could both get tested together and know each others results.his saliva test came back non reactive and mine came back reactive.we walked all the way there in the heat and im pretty outta shape so im not sure if that could of threw off the test.the lady who did the test said the line was very faint and showed up towards the end of the test.they took my blood and sent it to the lab to confirm my results.my blood test came back negative.i was with my partner and only him for six months when i got a reactive result but a neg blood test.i haven't had any symptoms of hep c but am worried.is it possible that it could of been a bad test and my health is fine?ive never used drugs or been with anyone who does.im now with a new guy that ive been with for about 3 months.i know he's clean but 2 weeks ago he broke out in really bad hives and went to the er.they gave him prednisone 10mg and he started taking them.about 2 days into taking them he started having high fevers that were only at night.the er told him to stop taking the meds so he stopped.that day he got into a car accident and had a neck and back injury and put him on anti inflammatory,pain,and muscle relaxer meds.but he was still running a fever only at night along with back pain and some mild shortness of breath.also he started running a low body temp(96.7) and sweating only during the day.he started to look pale and a little yellowish(to me) but he is puerto rican but the whites in his eyes were fine.he went back to the er and his white blood cell count was normal but his heart and liver enzymes were slightly elevated so they kept him over night to evaluate him which went back to normal.they couldnt figure out why this happened or whats causing it along with running fevers only at night but no night sweats.the dr did ask him if he wanted a hiv and hep c test done which he agree to.we have to wait 5 days for the results and im so scared he has hiv or hep c!!!and i might have it even tho i have no symptoms.any thoughts or answers would really help.please im just so scared and worried!!!!thanks for your time.Could hiv show up in the saliva before blood?could hep c cause a false positive result for a antibody hiv test?
No and No. HIV can't be detected in Saliva, ever, unless you mix saliva with the actual virus.





You produce a completely different anti-body in response to Hep than you do to HIV, so no.
