What Can Cause A False Negative Hiv Test
Hello. Can type 1 diabetes cause a false negative hiv test I tested for hiv ab/ag at 3 months negative and hiv1, 2 at 6mnths negative Is it conclusive?
Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
1 out of 12 is a false negative in oraquick hiv test. If I use the kit first time after 6 months from exposure (enough time for antibody generation) and use another new kit again after 12 months. Can the result be considered conclusive in that case?
Screening only: If you want a definitive test, you will need to have your blood drawn. And you will get your answer now. Love safely regardless and best wishes. ...Read more

If I get infected with HIV on june and infected with HCV in november, would this give me false negative hiv test 6 months last exposure in december?
What's the possibility of getting a false negative HIV test, when it was done at a clinic, blood was taken from my arm and sent away to lab?
Depends: It depends on how long ago did you have any exposure, and what test is being done. Antibody tests may take 6-12 months to turn positive. An HIV nucleic acid test, if negative, at about 12 weeks after exposure essentially rules out HIV. Any test, if done too soon after exposure will not give a reliable result. ...Read more
Was wondering in 2012 I did a HIV test which is neg & partner was neg, now 2015 both our HIV test are neg is there ever a false negative? Mono 3yrs
Nope, no false negs: HIV tests are never false negative more than a few weeks after infection. Mononucleosis doesn't persist 3 yr, but I'm even more certain you don't have HIV. Keep working with your doctor if you remain concerned -- or consider a visit to your local nationally suppored sexual health centre. Collectively, Australia's SHCs probably are the world's most expert network of STD/HIV clinics. Good luck. ...Read more
Hiv test read negative was told by a nurse I should be take hiv meds. How is this possible what's the chances of false negative
Yes: Standard HIV screening tests actually test for the presence of antibodies that the body makes to fight the HIV virus. False negatives are most commonly due to testing too soon after exposure. The period of time for the body to make antobodies is called "the window period". It varies in each person, but it is usually between 3 to 6 months. ...Read more
Is it possible to have a false negative rapid HIV test well after window period (9 months after last possible exposure)? If so, why?
Unlikely: When sufficient time has elapsed after one's last potential exposure, HIV tests are usually reliably positive if one is in fact infected. One has to be aware that the usual test looks for hiv-1, but there is also an hiv-2 which is far less common but could be in you and the standard test would not recognize it. ...Read more
Possibility of false negative after 6mth period HIV test? Gave oral to partner in question now I have lesions on the tounge maybe ohl, could be hiv?
What type of test was done? A test for HIV nucleic acids, if negative at 6 months after potential exposure, would rule out HIV infection. If it was antibody test, it is good but it would be prudent to repeat at one year after exposure. See the following for safe sex guidelines.

What can cause false positive ELISA HIV test? 2 confirmatories neg and viral load neg. No bands detected.
An elisa test for HIV is very sensitive which basically means it is a good test for ruling out HIV and is only reliable when negative. A positive elisa test does not mean someone has HIV and is frequently called a "false positive"
there are many causes of a false positive which include liver disease, blood tranfusions, infections, autoimmune disease and dumb luck! ...Read more
Wht cause a false pos ELISA HIV test with neg naat and western blot? 2 neg oral fluid rapid results. After 1 year exposur. Ihave autoimmune hypotyroid
No answer: Please. How many times are you going to ask the same question. There is no right answer here. Your body has something triggering the simple HIV antibody test to be positive. It is not HIV causing this symptom. In the future you should avoid these tests and get the better test. You have been given this answer numerous times. It is time to move on. ...Read more
Can Truvada for 21 (stopped at 4 weeks past possible hiv exposure) cause a negative hiv test result at 11 weeks past possible exposure?
Yes & No: The purpose of the Truvada as I understand your question was to prevent HIV after you had an exposure to it. Assuming this is the case, then a negative HIV result could be that the Truvada did it's job or that your exposure was minimal and you did not contract HIV - Either way at 11 weeks, it's pretty safe to say you are HIV- and unless you have had another exposure will remain that way. ...Read more
I am at my 23 week last exposure to hiv. I got scratched today with an object. If it was hcv blood in it would it give me false neg hiv test at 24 week?

A friend had hiv test at 6 months last exposure negative, now he had a pos for hiv-2 at 7 months. He also did a pcr at 4 months. Can it be false positive?
Probably false pos: HIV-2 is very rare outslide the area of west Africa where it originated (Cameroon), although I don't know about Albania for sure. The PCR should have picked up HIV-2 as well as HIV-1. So your freind's HIV-2 test probably is false positive. He should see an infectious diseases or HIV expert to sort it out. ...Read more
When the hiv test is conclusive? .what causes repeated perianal fungal infection? Last hiv test 14monthes postexposure. Is negative?
No worries: Every HIV test that exists, anywhere in the world, is conclusive by 3 months. The most commonly used tests are conclusive by 4-8 weeks. For sure your negative result at 14 months proves you don't have HIV, no matter how high risk the exposure (and if not reexposed), and no matter how typical the symptoms. Entirely healthy people often get perianal fungal infections; it's not a sign of HIV. ...Read more
There are several ways to detect the HIV virus. The first is by antibodies. This includes eia (enzyme immuno assay). The rapid HIV tests are these types. The second way detects proteins on the viral coat (western blot). This is a gel plate electrophoresis. Thirdly there is pcr (polymerase chain reaction). This detects and amplifies dna allowing a viral ...Read more
