HIV test and testing prerequsites Dec 28, 2010 Sir, I just have 2 concerns that I am putting forward to you: 1.Is there any restriction / preparation for HIV testing like empty stomach or full stomach or 2 hours after taking food or water or is it that any body can go /walk any time and do the testing ? 2.I have tested HIV 2 times on 2 different methods and they are as follows : The first report is: Rapid Screening test for HIV 1 and 2 antibodies HIV 1 NON-Reactive. HIV 2 NON-Reactive Method Immunochromatography. Kit used HIV TRI DOT LotNo. HTD 091024 Note : All reactive samples should be cross checked with a different ELISA system and /or Western B lot test for information. Remarks: The second report is : Detection of HIV p24 antigen and antibodies to HIV type 1 and/or HIV type 2- Result: Non-Reactive (0.19) Chemilluminescent Microparticle immunoassay (CMIA)(Architect, Abbott) (This is a screening test and there may be false positive and false negative results in a small percentage of cases for various reasons.) Interpretation: - <1.0: Non-Reactive >/=: Reactive Is the above two method of tests(Rapid test and CMIA) is sufficient or should it be tested in a ELISA or any other method ?
