After a 8 year exposure and a 12 month exposure I just got tested for std rpr and hiv duo @ 1 3 6 12 mos and fta abs at 12 mos is it conclusive?

After a 8 year exposure and a 12 month exposure I just got tested for std rpr and hiv duo @ 1 3 6 12 mos and fta abs at 12 mos is it conclusive?

No syphilis or HIV: For sure you don't have HIV or syphilis, no worries. You have been seriously over tested. The HIV duo test is conclusive any time 4 weeks or more after exposure, and the RPR syphilis at any time 6 weeks or more. YOu didn't need an FTA-ABS test, and all HIV tests beyond for weeks were wasted money. You also should have urine or vaginal swab tests for chlamydia and gonorrhea. ...Read more

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

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.

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.

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. ...Read more

What are the odds of being hiv infected from a one time exposure with an unknown status man with ejac/vag. I know it's risky but what are my chances?

What are the odds of being hiv infected from a one time exposure with an unknown status man with ejac/vag. I know it's risky but what are my chances?

Depends: If your sexual partner has untreated HIV, then you have a good chance of contracting the infection. There is no way to tell what the probability is since there are so many factors involved. If your sexual partner is not infected by HIV, then your risk is zero. Nonetheless there are STDs other than HIV to consider as well. ...Read more

What percent, is a negative Hiv test result. At 6 weeks? Do I most likely not have it then. And what are the odds of contracting it one time exposure

HIV nucleic acid: Test. A negative antibody test at 6 weeks does not exclude HIV infection. A negative HIV nucleic acid test would. The odds of getting the infection depends on the type of exposure and the viral load in the fluid to which you were exposed. ...Read more

Can you please tell me the HIV symptoms at one year possible exposure?

Generally none...: While some people infected with HIV for one year might have some symptoms (possibly mildly enlarged lymph glands and feeling tired), many people would be complete without symptoms. They could be infected without knowing and could pass the virus to others without knowing. ...Read more

9 months after exposure I tested negative for hiv. Am I ok or is there still a chance I caught it?

Very slim: A handful of persons have been documented as converting from negative to positive 12 months after an occupational (non-sexual) exposure to hiv. Most individuals who become infected will have a positive test by three months after the exposure, many even sooner. ...Read more

Do I need further HIV testing if I had only one exposure and was before 6 months of test? Even if I had symptoms?

HIV nucleic acid: If you had a HIV nucleic acid test, six months after exposure, and it was negative, you do not have HIV. The symptoms may be due to some thing else.
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, if you have sex. ...Read more

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?

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?

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. ...Read more

Should I get an HIV test one week after a possible exposure?

Should I get an HIV test one week after a possible exposure?

Too soon to test: You could have taken prophylactic treatment within a day or so of the exposure. However, testing one week after exposure will not be meaningful. If the result is negative it would not rule out HIV infection. The fastest and most specific way to diagnose would be to get a HIV nucleic acid test after 3 months, if the antibody test is negative at that time. ...Read more

Is a negative HIV test after 2 months of exposure accurate? Is there a chance it might be possitive now?

Less likely: But you should continue to be retested for at least 6 months. Test at 3 and 6 months. Or if you want to be sure immediately you can have an RNA pcr done which will tell you immediately whether there is any infection, but it is $$$$. The overwhelming chances are that if you were tested with latest technology that you are negative. Be careful out there. ...Read more

When should some one be considered Hiv Negative after exposure when antibody only and Duo combo tests used?

When should some one be considered Hiv Negative after exposure when antibody only and Duo combo tests used?

Depends: Antibody tests are positive in most infected people by about three months after exposure. In a small number the test may not turn positive for a year. Combo test is more reliable and at about 6 months after exposure, a negative result should rule out HIV. However, the best test is for HIV nucleic acid, if it is negative at three months after exposure that would rule out HIV. ...Read more

Negative HIV duo and 3rd gen. 7 weeks after exposure. But 3 weeks after pep. What are my chances of being infected?

I see a reply here where one specialist mentioned hiv test at 6 wk, 3 mnt, 6 mnt, 12 mnt & 18 mnt after exposure. Is this true if risky exposure?

No, not true: According to all HIV experts, whoever advised that is mistaken. It is never necessary to test later than 3 months after exposure, and most tests are conclusive 4-8 weeks after exposure, depending on the particular test or combination of tests. ...Read more

How conclusive is 4 th generation HIV testing after 4 wks exposure when negative and what are chances of positive in 3 mt window period?

Repeated questions: It is offensive and an abuse of this powerful application to keep asking questions that have been answered already. Here is my answer as an? HI.v expert who tests fife to ten patients daily. At four weeks I would never offer you the fourth generation or other HIV antibody test. I think it malpractice to do so. This early you would get the 100% accurate RNA test. ...Read more

Worried about HIV infection. I got a 4th generation rapid test exactly one month after possible exposure. It was clean. Is this conclusive?

Highly reassuring...: ...but maybe not conclusive. The lab-based 4th generation ("combo") HIV tests are 100% conclusive at 4+ weeks, but less confidence about the rapid version, because it's newer and rapids are inherently a bit less reliable. Your negative is over 95% reliable. But if your exposure was especially high risk (e.g. unprotected anal with male partner) have a lab based test, or repeat rapid at 2-3 months. ...Read more

Had negative HIV tests up to 12 month post exposure. I'm pregnant and require to have another one done. No other exposure, shouldn't worry about change?

No worries: Correct. The HIV tests are among the most accurate diagnostic tests ever developed, for any medical condition, and are 100% reliable any time more than a few weeks after the last exposure. If you are not reexposed, your HIV test result will never change. ...Read more

Do you know which HIV test take after one month exposure. I had unprotected sex with prostitute?

Multiple tests: After exposure to HIV or after high risk behaviors (like unprotected sex) it is recommended that you have multiple tests performed. You should be screened for other stis, like chlaymydia, gonorrhea and syphilis as well. Hiv and syphilis are blood tests that should be tested multiple times over the next 6 months to ensure that you didn't contract either infection. ...Read more

Is a HIV negative blood test (antibody test) after 6 month from exposure conclusive? Or should I take another one.

Relax, Don: It's unlikely that your HIV screen would be negative six months after your risky event. You're welcome to repeat in a year or pay a big charge for PCR (which would be absolutely definitive). I suggest you just get on with your life, having learned from your adventure and hopefully loving both more wisely and more meaningfullly. We all make mistakes, little brother.

Would cured/treated primary complex at 5 years old affect hiv test result at 25 years old, 9 months after exposure? Primary complex was just one-off

Would cured/treated primary complex at 5 years old affect hiv test result at 25 years old, 9 months after exposure? Primary complex was just one-off

No: Primary complex if tuberculosis (TB). Having TB currently or in the past should not alter the results of modern HIV tests. If a person is not monogamous with an HIV-negative partner, meaning she has other possible but low-risk exposures, she can get see her primary care doctor and ask about routine screening. It might be annual testing. ...Read more
