Hiv (Definition)

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

2009- ELISA HIV test- positive, western blot- neg. 2010-oraquick negative. 2014- elisa-indeterminate wb- neg. Low risk for hiv. Could I have lupus?

2009- ELISA HIV test- positive, western blot- neg. 2010-oraquick negative. 2014- elisa-indeterminate wb- neg. Low risk for hiv. Could I have lupus?

Not a test for lupus: The HIV test is not a test for lupus. What's clear is that you don't have hiv. You'll never know why your elisa was positive and then indeterminate, and it's not worth investigating. False positive elisas are not uncommon; that's why they have to be confirmed with western blot.

Would any form of ibd cause a false positive ELISA HIV test?

Would any form of ibd cause a false positive ELISA HIV test?

HIV testing: Inflammatory bowel diseases are a form of immune dysfunction, and as such can be considered a potential source of biologic false-positive results on tests that are very sensitive but non-specific. That is why confirmatory testing is needed.

Can MS cause false positive ELISA HIV test?

No: MS does not affect blood tests, and specifically does not cause positive ELISA HIV test, See infectious disease doctor.

Is HSV 2 an infection? Is HPV an infection? Are either of these a cause to false positive ELISA HIV test?

Infections: Both hsv-2 and hpv are infections caused by viruses. Probably they will not cause a false-positive HIV elisa. However, see what the western blot shows.

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!

GOING TO GET HIV TEST. I HEAR HEP B VACCINE CAN CAUSE FALSE POSITIVE. GOT 3RD SHOT LAST WEEK. ANY ADVICE. I DON'T NEED STRESS OF FALSE POSITIVE. TY?

GOING TO GET HIV TEST. I HEAR HEP B VACCINE CAN CAUSE FALSE POSITIVE. GOT 3RD SHOT LAST WEEK. ANY ADVICE. I DON'T NEED STRESS OF FALSE POSITIVE. TY?

You heard wrong: There are no medical treatments, vaccines, or illnesses that have any proved effect on HIV test reliability, and the hepatitis B vaccine certainly cannot do it. Your HIV test will be reliable, as long as it is done sufficiently long after the last possible exposure.

Can healthy people get false positive ELISA HIV test? If so why?

Yes, it is possible: Some people may have a biologically false-positive test for hiv, when tested by elisa. Such people usually have a negative or indeterminate confirmatory test, the western blot. That usually happens because of some antibodies that were directed against other organisms recognizing part of hiv. If there is any question, a qualitative HIV dna pcr may put the question to rest.

Can healthy individuals get false positive ELISA HIV test? Final question. Does it always mean there's something wrong with someone if they get this.

Can healthy individuals get false positive ELISA HIV test? Final question. Does it always mean there's something wrong with someone if they get this.

Yes and No: Healthy people can get a positive screening test for hiv. Screening tests have high sensitivity but not very high specificity. Many issues can cause a false positive including flu vaccination. Mostly the cause of false positive is not known and it is not because there is anything wrong with the person who gets a false positive test.

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?

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.

Is genital herpes a reason to produce a false positive ELISA HIV test?

Is genital herpes a reason to produce a false positive ELISA HIV test?

Asked and Answered: No. Absolutely not. But there is a link. Having hsv 2 makes your risk of contracting HIV five times higher than those without hsv 2.

False positive ELISA HIV test after 2 years expsure. Autoimmune disease? Will I ever know why? Does this mean something's wrong?

False positive ELISA HIV test after 2 years expsure. Autoimmune disease? Will I ever know why? Does this mean something's wrong?

No answer: False positive can be from many reasons including mistaken labeling. If it was a false-positive, there is nothing for you to worry about. It is the false-negative that should worry you.

Does a false positive ELISA HIV test mean someone has a autoimmune disease? Or could it be anything? Do people find out why they get these results?

No: While false positives can be from nothing specific, they can be related to infections from other viruses that may make similar antibodies that can react with elisas, but this has to be confirmed with western blot. I personally would ask for two confirmations as it can take up to six weeks for viral levels to be high enough to be sure with the test. Check with infectious disease doc to be safe.

Tested false positive ELISA HIV test last month. Negative ifa and western blot and naat. 2 negative oraquick all 1 1/2 year post exposure. Hiv?

Tested false positive ELISA HIV test last month. Negative ifa and western blot and naat. 2 negative oraquick all 1 1/2 year post exposure. Hiv?

Negative: If nat was negative at 6 months after exposure you not likely to have hiv. Given all the negative test results, you should not worry about the one apparently false positive.

Hiv Test (Definition)

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
