Hello Dr. is an RPR test and HIV 4th Gen ab ab 1/2 test conclusive at 14 weeks. thanks?

Rpr (Definition)

Rapid plasma reagin (rpr) is a blood test that looks for non-specific antibodies that may indicate that the organism (treponema pallidum) that causes syphilis is present. The term "reagin" means that this test does not look for antibodies against the actual bacterium, but rather for antibodies against substances released by cells when they ...Read more

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

Will tremponal tests (eia, ClIA ) become positive before non tremponal tests (rpr,vdrl)?

Will tremponal  tests (eia, ClIA ) become positive before non tremponal tests (rpr,vdrl)?

It can happen: Revised reply: disregard earlier one if you saw it. At first I misunderstood the question. The newer TP specific IgG/IgM tests (EIA etc) and RPR/VDRL have similar seroconversion times, typically 4-6 weeks. The IgG tests often are positive first, but exact frequency of this isn't yet known -- more study needed. Apologies again if any confusion from earlier reply. ...Read more

I was tested for syphilis. RPR was pisitive(1:1) and TPPA was negative. Does in mean i am infected?

Syphilis: Probably not. The RPR is a screening test which is very sensitive but not as specific, so that you can have false-positive results. The TPPA is far more specific and used to detect the RPR positives that are falsely positive. ...Read more
