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

Asked yesterday but question was not really answered. Which comes positive first for syphilis RPR or cia?

Asked yesterday but question was not really answered. Which comes positive first for syphilis RPR or cia?

CIA?: An appropriate syphilis test involves two stages: the RPR is done FIRST- if positive, a confirmatory test such as an "FTA-ABS' or an "EIA for TPA" must be done. The 2-stage test is more cost effective and decreases the number of 'false positive' results. Discuss this important question further with your ordering doctor. ...Read more

What can cause a false negative from a HIV 4th Gen combo and RPR for Syphilia?

What can cause a false negative from a HIV 4th Gen combo and RPR for Syphilia?

But I wonder if you are confused about terminology? If results are negative, your question should be about false negative results. If neg results at more than 4-6 weeks, you don't have HIV or syphilis. Period. ...Read more
