Brief Answer: Oralsex lowrisk for HIV.Antigentest rulesout HIV Detailed Answer: Hi XXXXX, Welcome to XXXXXXX Thanks for posting your query. I can understand your concern. Unprotected oral blow job carries a very low risk for HIV. As per CDC,Atlanta, penetrative vaginal sex is considered to be one of the high risk activity and it has a risk of 5/ 10000 exposures only and oral sex carries a low risk means you can understand the remote possibility or almost negligible. So you need not worry about your sexual activity at massage parlor. Regarding the tests for HIV, all the tests done by you are carrying a high degree of specificity and sensitivity and the latest Id XXXXXXX test is almost 100% sensitive. But the thing is, all the test done by you were all antibody detection tests. Antibodies against HIV in the presence of infection can occur only after 60 days and these results are more conclusive after 90 days. If you are so anxious to get tested earlier (not necessary with oral sex) you can go for Antigen tests like P24 Antigen test, DNA PCR test or a 4th generation Combo/DUO test. That will rule out the HIV possibility as early as 10 days itself and more conclusive after 4 weeks. Do.t worry you will not have HIV. Dr S XXXXXXX

Brief Answer: CMIA Combo test rules out HIV. you are HIV free Detailed Answer: Hi, Welcome back. CMIA technology can be used to detect both antibody and also antigen. If it is used as a combo test which can detect both antigen and antibody test, then you need no further testing. It is conclusive that you are free from HIV. Dr S XXXXXXX

Hi sir, Feels good to listen from a expert you are hiv free. Kindly dont mistake me I am asking again. One more doubt the XXXXXXX test report is saying that XXXXXXX screening done for viral RNA/DNA HBV : NOT DETECTED HCV :NOT DETECTED HIV 1/2 :NOT DETECTED is it not more accurate than cmia sir. Can I have unprotected sex with my wife. Anxiety plays a big role than the infection sir.any how I will stop testing and go back to dubai. thanks for all reply and last reply expecting sir. Will pray to god he gives long health and happiness in you and your family. Thank you sir .

Brief Answer: XXXXXXX not detected HIV DNA/RNA.HIV free confirmed. Detailed Answer: HI, Welcome once again. Really speaking, I had no experience with Id XXXXXXX But nuclear amplification tests for HIV antigen is a common technique and highly reliable. Same principle is engaged in Id XXXXXXX You had sent the version of your test. It clearly meant that this test was performed to detect HIV Antigen (RNA and DNA). Naturally antigen based tests detects the infection as early as within week of infection. But this also becomes more conclusive after 3-4 weeks. Your test performed on 20 days (3 week) after the risk activity.So you need not have any more test as it was only a oral contact. I still assure that you are HIV free. You can have sex with your wife without any protection and hesitation. You and your wife will be safe. Dr S.Murugan

Brief Answer: Test value is less than cut off value. HIV free Detailed Answer: Hi, Welcome back. You need not bother about cut off values. Every test has a cut off value as indicated in the instruction manual as per the marketing company of each test kits. Your test value is far less from the cut off value. So the test is expressed as CMIA is nonreactive for HIV. Test performed correct only. So just forget the past incident and carry on you routine work. Have great day. Dr S.Murugan

Brief Answer: Both antigen and antibody tests ruled out HIV. Detailed Answer: Hi, Welcome once again. Antigen test is more reliable as it is recognizing the viral particles itself than that of antibody tests. For you, both ELISA for antibodies against HIV, HCV, HBV and Antigen screening for HCV,HBV and HIV 1&2 had been done and all were negative. ELISA at 33 days can not be considered as conclusive where as a negative ID XXXXXXX for HCV, HBV and HIV is very much conclusive and reliable. Don't rely the technicians word. You need no more test. You are free from HIV,HCV,HBV infections. Just forget about the past incidence and concentrate on your daily routine. You need no guilty complex about the same. Good day to you. Dr. S.Murugan

Will this any how affect the result of elisa. Kindly reply for this doubt sir. Sir you have made all my doubts clear in the past and now i have come to 95 % normal after having discussion with you sir. And Wishing you a Happy New Year Sir. Let 2014 bring you all XXXXXXX and happiness in you and your family.

Brief Answer: Drugs mentioned by you not affect the results Detailed Answer: Hi XXXXX, Welcome again. Thank you for your New Year wishes. Definitely 2014 is going to bring a lot of fortunes and success. XXXXXXX test detects viral particles and no drug will interfere the outcome or delay its sensitivity. Drugs like Atarax, AF 4oo, and Imol tablets are not related to steroids and don't have any immunosuppressive action and therefore it has no effect on ELISA. So nothing to worry and you are HIV free beyond any doubt. Wish a happy New year. Dr S.Murugan
