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

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

How common is it to get a false negative RPR test result I've take three since January all non reactive?

No false negatives: The RPR test is always positive within 6 weeks of a new syphlilis infection. False negative RPR test results are exremely rare. You should stop testing. If you have symptoms that make you suspect syphilis, you can be confident it's actually something else. See your doctor or the STD clinic if you remain conerned. ...Read more

I've had three RPR test since January at 2 week 8, and 14 weeks all non reactive is there any reason I should think I have Syphilis?

No: With 3 negative RPRs since January, there is no reason to suspect syphillis unless you just contracted it. There is much more risk of false positive test results with RPR than false negatives. Hope this helps. ...Read more

I was tested RPR and tppa test and elisa, with negative results but in rapid test with immunochromatographic assay I was reactive, what does it mean?

I was tested RPR and tppa test and elisa, with negative results but in rapid test with immunochromatographic assay I was reactive, what does it mean?

No syphilis: The newer syphilis blood tests, including the rapid tests, measure IgG antibody. They often give false positive results. The current consensus among STD and syphilis experts is that syphilis is not present when the RPR and standard confirmatory tests (e.g. TPPA) are negative, regardless of rapid or IgG tests. In your case, you also have a negative ELISA test. You definitely don't have syphilis. ...Read more

Hiv test. Says negative but RPR says non reactive does my HIV test sugguest I could have aids? Took hiv1 and hiv2

No: If I understand your question correctly, the report says your blood tests are "non-reactive" for hiv. That means there are no antibodies in your blood against the virus, suggesting you have not been exposed to it, in other words the test is negative. "non-reactive" does not suggest you have aids. ...Read more

Painful sores: If you have painful sores, I would think about herpes simplex (lips or labia?). Anyways, primary herpes simplex can cause pretty extensive sores. I don't understand how you are reporting. No treponema tests (RPR) usually recommended as first line and treponema tests for confirmation. The FTA is 96% specific, Although uncommon, A false positive- which can be seen w/ APL Ab syndrome can occur ...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

Hi. I had a RPR positiv in 2010. After the tretman was non reactiv. Last year was non reactiv again. I had my blood test again this year positiv?

Be patient: This can be frustrating especially if you have no new exposures. But, remember syphilis is gotten skin to skin, blood to skin, semen to skin and in rare cases saliva to skin. If there is a chance of a new infection please take the treatment again. If there is no new exposure possibility then there should shortly be a antibody titer that can be compared to your previous titers. ...Read more

False RPR test what cause them?

False RPR test what cause them?

Syphilis Testing: I am very curious by your question. It is difficult to have a false positive for syphilis so I would make sure that you are getting the right information and that a follow up test is scheduled. Latent syphilis can have deadly consequences so making sure you are un-infected is paramount.

You may be interested to know that syphilis can be contracted by skin to skin, saliva and blood and semen. ...Read more

My RPR test was a positive with a titer 1:1 for syphilis. What does that mean? Is that bad?

Syphilis testing: All syphilis is "bad": it is a very dangerous infection, even if causing no symptoms at this time. However, low positive results might indicate you were treated without knowing it, e.g. if you received certain antibiotics for other infections. Or it might be a false positive test, so confirmatory testing is needed. Discuss w/ your doctor, or best to see an STD or infectious diseases specialist. ...Read more

Worrying for nothing: But, miss, your worrying for nothing is taking time away from real medical problems on this site. Please stop asking the same question. I think I have counted over ten times asking the same question. That is offensive, bothersome and rude behavior. The answers are not changing.

Perhaps it is time to get yourself to a psychiatrist to figure out why you feel it is appropriate to be so paranoid. ...Read more
