What Can Cause A False Negative Hiv Test
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?
No and yes: HIV test is not affected by other disease conditions. A negative test at 6 months tells you that you didn't have the infection from that encounter. However it would not have ruled out HIV if you had been exposed to HIV infected blood or secretion subsequently. ...Read moreSee 1 more doctor answer
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

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?
Whats 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
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
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 does't persist 3 years, but even more certain that 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
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?
Depends: 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.

What can cause false positive ELISA HIV test? 2 confirmatories neg and viral load neg. No bands detected.
Many things: 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

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
