Question 1

is a 4th gen ab/ag hiv test accurate after 21 days of exposure or what % of accuracy i can expect from it as many doctors say 4th gen is reliable after 28 days?

Accepted Answer

HIV: Typical testing regimen is at 1 month (more than 28 days) and 6 months. If either is positive, you will be offered medications that reduce the viral load in your bloodstream. You should talk to your Dr about using PrEP while you are waiting for results, and even if they come back negative. These prophylactic meds can prevent HIV infection during high risk encounters.

Question 2

if i had an hiv test 25 days after possible exposure and it came back negative is that pretty reliable? it was an antibody and antigen test

Accepted Answer

HIV testing: You should be followed up with a repeat test at 3 mos, but the test you had is fairly reliable by itself. The problem is the rare individual whose tests become positive later than the 25 period you mention.

Question 3

how long after the exposure  should i wait to get a 100% accurate and reliable result for hiv test?
3 or 6 month

Accepted Answer

6months: Usually test is conclusive after 6months .There have been some rare cases where sero conversion took up to a year to occur

Question 4

how reliable (percentage of accuracy) of 4rd generation hiv test (duo test) at 14.5 day after exposure ? thank you very much

Accepted Answer

Depends: It is accurate if positive. However, two weeks is too soon to rule out infection. At six months after exposure, get a HIV nucleic acid test, if that is negative, it would be definitive indication of being HIV free.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex.

Question 5

how reliable is a negative result from an abbott architect ag/ab combo hiv test (4th generation) taken at the 28th day after possible exposure?

Accepted Answer

100%: A negative combo test is 100% conclusive any time 4 weeks or more after the last possible exposure. This result proves you didn't catch HIV and no additional testing is needed.

Question 6

how reliable is pcr hiv test 1 month after an exposure?

Accepted Answer

Not the best test: The better test 1 month after exposure is either a standard serology (elisa with confirmatory western blot if positive) or a 4th generation antibody/antigen test.  Hiv PCR (viral load) will usually be positive, but false positives and negatives can occur,  so it's an imperfect diagnostic test.  Viral load is used diagnostically mainly in people with symptoms of acute infection.

Question 7

how reliable is a negative hiv test 23 weeks after possible exposure?

Accepted Answer

Depends on the test: A negative test for HIV nucleic acid will rule out HIV at 23 weeks after exposure. Absence of HIV antigen will essentially rule out hiv. Absence of antibody will more or less rule out HIV but should be confirmed with HIV nucleic acid test.

Question 8

are hiv rapid test reliable? there is debate on the sensitivity of the test. i had a neg. rapid hiv test 18wks after exposure, should i stop worrying?

Accepted Answer

Repeat testing: It can take 3 - 6 months for the HIV antibody test to become positive if people have been exposed. We usually repeat at 6 months to make sure. It is very important to use condoms with all sex to avoid being exposed or exposing others.

Question 9

i've had a hiv test after 60 days of exposure -- is western blot test a better option?

Accepted Answer

No-: Inferring a concern about a negative HIV screen, at 60 days,  the current generation of HIV screens are very sensitive. Therefore, if the screen was negative, then the WB will not be any more  sensitive

Question 10

how precise is an hiv test 14-19 days from exposure?

Accepted Answer

Which test?: If the test is positive, it is accurate, a negative test this early does not exclude hiv. See this site for more info.
