Avatar f tn Is HIV screening test (using blood sample) is a standard antibody test for HIV ???
Avatar n tn The rapid test came back as negative on the day and 2 weeks later the ELISA test came back as positive and the western blot test is indeterminate with a single band presented given a moderate reactivity to p24. I was shocked and scared. The doctor took another sample on the day he gave me the result. Now at 4 weeks after the unprotected sex, I had a Negative Rapid test and still waiting for result of the ELISA test.
Avatar m tn Of course ELISA test can be indeterminate. No an ELISA test is not that much different than a Rapid test. One takes a machine to process while the other doesn't.
Avatar n tn I heard that the during the ELISA test, the laboratory assistant will divided the sample into several parts? Isn't it? If so is that mean it actually test each of the parts? For example if they divided it into 5 parts, that will be make five tests and get five result, if one of them is positive then they will re-test to confirm. They do this in order to avoid the tests-mistake such as reagents mistakes which is sometime cause the false negative. Am I right?
Avatar n tn second question, the ELISA test is confirmewd through WB test, only or by subsequent ELISA test with the SAME SAMPLE, that is, for the confirmation is always necesarry a second sample?
Avatar m tn How accurate is RAPID IMMUNOCHROMATOGRAPHY SAMPLE SERUM TEST FOR ANTIBODIES @ 3 MONTHS POST EXPOSURE
Avatar m tn 369 and sample of absorbance 0.149... and afte 1 month ( after 3 month of exposure ) my elisa result was non reactive and cut off value 0.509 and sample of absorbance 0.169.. ...
Avatar m tn Secondly, you need a test at the 3rd month with an antibody test. Could be ELISA, CMIA, ELFA etc. As long as it is an antibody test it works. ELISA is just the technology of the test used to detect antibody. However, it's the most conventional technology and widely used. Thirdly, oraquick is an antibody test and uses the ELISA technology.

Avatar m tn does this test covers all subtypes and groups of hiv or do i have to under go separate tests, and i have not done any elisa test so do i have to take an elisa or the test westernblot is enough, i have also taken an dna qualitative pcr which was negative, and one more thing i would like to add is that they have tested my sample 6 days after they had drawn nlood sample of me , could that might have affected my results please give me some adivice as since my partner have tested positive i am i a p
Avatar m tn Knowing that clinic may take the ELISA test, I guess after few days they will send the blood sample to laboratory for test result. Does the result remain accurate after storing the blood sample for few days? 4. I have been taking nicorrette for 5 months, do this impact my test result?
Avatar m tn I just did my hbsag elisa test it come positive with- TEST OD 2.45 AND CUT OF VALUE IS 0.10 is it can be fixed or can't.
Avatar m tn that s a useless number, there is no unit.
Avatar m tn hi sir my elisa test after 5months report is negative and my reoprts description is this SEROLOGY Test Description Value Observed Biological Reference Interval Accreditation HIV 1 & 2 0.60 Index Value Non Reactive: Index Value = 1.0 Interpretation  Non Reactive result implies that no Anti HIV -1 or Anti HIV -2 antibodies have been detected in the sample by this method.
Avatar n tn The doctor told me that my ELISA test was positive and so they sent my blood sample for an Antigen Western Blot test which came back negative. The doctor told me that 99,999% the Elisa test was false because of other factors that might affect the blood but he asked me to retest in one week. Is it possible that I have contacted Hiv? If so, how? I used a condom and it didn't break. I also cannot have Hiv from previus relationships because I tested Hiv negative 9 months ago.
Avatar f tn I had a test done I'm assuming an elisa. My doctor said it was negative. I just don't understand why I'm getting billed for a confirmation test which is a western bot after positive elisa? I always thought if you have a positive elisa, you are told by the Dr and have to get further testing through the western bot.
