Question 1

can my hiv negative be a false negative?

Accepted Answer

Maybe but unlikely..: Timing can be important in HIV testing.  If testing is conducted within a very short time of possible exposure, then it is possible for a false negative result.  In general, current HIV tests are highly accurate.  If you are concerned, then a retest may help.  It would be good to discuss your exact situation and dates of exposure and testing with a doc or at a clinic where testing is performed.

Question 2

tested nonreactive hiv rapid test 3yrs after 1st and last sex cntct. is there a possible false negative? am i really free? help!

Accepted Answer

Free: Three years after a potential exposure a negative HIV result means you do not have HIV infection.

Question 3

what are the chance of getting a false negative hiv result 8 months prior to last exposure. i had 2 negative test at  4 weeks and 2nd one at 8month.

Accepted Answer

HIV Testing: Typically, most people who acquire the infection have a measurable antibody titer by three months after exposure. If you were negative at 8 months, it is vanishingly unlikely that you had a false negative test result.

Question 4

wondering if possible exposure to hiv in jan2012 did test in august2012 was negative in 2014 retested again still neg any chances of false negative?

Accepted Answer

I would feel comfortable that you are HIV negative: it is possible to to have false negatives if you have some kind of interfering antibody That interferes with the test however this is unlikely. I would feel confident that you are HIV negative giving the two negative test that doesn't mean you will always be HIV negative you must abstain from risky behavior.

Question 5

what can cause a false negative from a hiv 4th gen combo and rpr for syphilia?

Accepted Answer

Nothing: There is no such thing as false negative results for either test, as long as done long enough after the last possible exposure -- 4 weeks for HIV, around 6 weeks for syphilis and the RPR test. Barring an unlikely coincidence, this is your second question along these lines. I don&#x27;t mean to sound insensitive, but do your best to suck it up, believe it, and move on. If you can&#x27;t, consider counseling.

Question 6

what is the possibility of a false negative 4th generation hiv test at 6 months ?

Accepted Answer

: Never say never, but if the test was done properly, you do not have HIV. HIV is only one of the STDs. A condom may not protect against HPV, Herpes, LGV, syphilis, pubic lice etc. It would be prudent to see your doctor for an evaluation.

Wish you good health!

Question 7

can you get a false negative in a  4th generation hiv test after 4 months past expusure?

Accepted Answer

May be: A nucleic acid test for HIV is more reliable.

Question 8

is there any chance my 4th generation hiv test could be false negative? from 27 days post exposure?

Accepted Answer

: It takes up to 45 days for the HIV AgAb (4th generation) blood tests to become positive. However, by 27 days 98% of infected persons test positive. Almost certainly you were not infected, but to be certain you need one more test after 45 days.

Question 9

are there drugs that affect the 4th generation hiv test? what is the exact and clear time for testing? will the test give a false negative even if we are sick? i tested on the 80th and 100th days and it was negative?

Accepted Answer

: No, none. Duplicate question; see reply to your other question.

Question 10

can expire  hiv dot kit give a false negative ?

Accepted Answer

HIV tests: Expiration dates are important because tests can have decreased sensitivity and/or specificity, just as expired medications can be less effective. Expired kits or kits which have been stored improperly can give false positives and false negatives. I hope your "false negative" turns out to be a "true negative". Good luck!
