what causes false hiv positive results

I took an HIV blood test at my doctors office on Thursday and I am still waiting for my results. I am now worried that I might get a false positive. Wondering what are the causes of false positive HIV test? My wife is 9 months pregnant now. Would this cause a false positive in my test?

Hi a few weeks ago I took a rapid results HIV test. The results was positive. Then I took the western blot to confirm this came back negative. After this I took the Viral load which said i have no virus. The doctors and worker at the hospitals hiv/aids program are perplexed. They had me do another viral load test which results will be known this monday. They also had me do another rapid two days ago which came back positive.

I would ignore your IgM test result. IgM tests for herpes gave many false positive test results and are not clinically useful. That your IgM test is positive does not mean that you have HSV-2 but could be a falsely positive result related to your positive test for HSV-1. It also appears that a week before your testing on 3/11 you had another HSV blood test which was positive at a level of 1.23.

In view of the low risk sexual lifestyle you describe, this is probably a false positive test result -- which you seem to realize, according to the title of your question. The rapid HIV tests are prone to give false positive results. It's not all that frequent, but it happens much more often than with the lab based tests. (This is one reason why rapid tests are not recommended except when a result is needed urgently. We recommend the lab-based tests in most circumstances.

Yes false positives do happen, when you get a positive result you get a Western Blot test which is a confirmation test.

Went to test to calm my nerves. What the odds this was a false positive? Could it have tested for a strain of HIV that the others don't? Going to my GP tomorrow to get another ELISA with a WB to either confirm or hopefully to undo a false positive. Help.

I know that a few years ago some clinics stopped using the rapid HIV tests with oral fluid because they yielded a high amount of false positive results. Do the rapid tests that use blood also give a high amount of false positives? I want to get tested one last time for final peace of mind so I can finally move on from this. But I don't want to take a test that has a significant likelihood of yielding a false positive, so should I just get the conventional blood test done? Thanks.

Could both of our 3 month test results been wrong? What is the likelyhood this test is a FALSE POSITIVE...or do I really have HIV?

For the small proportion who get false positive results however, the PCR test, when used for diagnosis (something that it is not recommended for) causes trouble because of false positive tests. Fortunately, these false positives are infrequent, but they do occur. There are not high quality studies which define precisely when we can expect totally reliable PCR results after an exposure, nor what the meaning of a positive PCR and negative Western blot means just a few weeks after an exposure.

Your HSV-2 test is in the low positive range where about 80% of “positive” results are actually false positive. Mono can cause a false positive. you can repeat the test, if it is negative, believe it. If it is positive, get tested with either a Biokit or Western blot to prove that it is a false positive. If either of these tests are negative, you do not have HSV-2. 4. the chance of the sore you had in the back of your mouth being HSV-2 are close to zero.

Candida infection is not associated with false positive HIV test results. If you want to reduce the risk of getting a false positive result my advice is to avoid the rapid tests. You will wait longer with the regular test, but the result will be more accurate.

I feel pretty versed in HIV, and have concluded that I had a false positive but I am still terrified. Anxiety is def. wrecking me - my dr said to retest in 3 months. 40 YO female- HSV2+ Exposures: 11.17 condom broke during a one night stand that I DEEPLY regret- he claims he is STD/ Drug free - I do not know anything about him. 11.30 protected vaginal sex-and oral with ejaculation in mouth- no sores or cuts in my mouth 12.6 protected sex and oral for quick second- no ejac.

Just imagine what anyone would go through if they receive false positive or indeterminate results due to lab errors.

Await your confirmatory results, and discuss with your doctor the reason for the multiple false positive ELISA results. If you had untreated HIV for 9 years, you would test positive on every possible test.

My symptoms only lasted about a week and I have felt normal since. Is it possible that the Mono test results came up positive due to HIV infection? And I don't have mono and I in fact have HIV?

re conflicting results, which one should I go with? And by the way, what would have triggered the false positive? Thanks again!

I have been reading a lot about the HIV PCR test and have read it has a high rate of false positives. Does anyone know what causes the false positives or is that rate based on some old research numbers?

Sorry, in your response I saw that I mis-typed. I meant to say 'I can consider it a false positive,' not 'false negative.' But I'm assuming you were aware of what I meant, even with the typo. Thanks again for all your help. I truly appreciate it.

i have read some where that rapid tests were not completely correct and there will be chances for false positive results....

PCR tests are well known to lead to false positive results and I suspect this. Sometimes false positive tests are transient and on some occasions they occur more regularly for reason that are unknown. I would suggest you find a local Infectious Diseases or HIV specialist to talk this through with. You need to know as much about this as possible in case it comes up again. As you do, please let us know what happens, we will all learn from your experience.
