How can you test for syphilis at home?
Syphilis is easily detected using STD rapid test kits which test individuals at home using a small blood sample. No lab work is required and results are within minutes displayed in the device. Syphilis is an extremely common STD and it is estimated that more than 90% of detected cases are within the developing world.
What lab test is an RPR?
RPR (rapid plasma reagin) is a screening test for syphilis. It measures substances (proteins) called antibodies that are present in the blood of people who may have the disease.
Is RPR test accurate?
A negative test result is considered normal. However, the body does not always produce antibodies specifically in response to the syphilis bacteria, so the test is not always accurate. False-negatives may occur in people with early- and late-stage syphilis. More testing may be needed before ruling out syphilis.

Most people become negative for RPR with adequate treatment, though some patients who present with later stage disease may maintain a low titer RPR (<1:8) for life despite adequate treatment. This is the serofast state. 4. Initial screening may be negative in early primary syphilis.
Is Vdrl the same as RPR?
The rapid plasma reagin (RPR) test uses the same antigen as VDRL, but the antigen is bound to a carbon particle to allow visualization of the reaction without a microscope. VDRL or RPR titers are monitored to document response to therapy. RPR titers are frequently higher than VDRL titers.
Can you use urine to test for syphilis?
There are no commercial urine tests available for syphilis or herpes. While the U.S. Food and Drug Administration (FDA) did approve an HIV urine test in the 1990s, it is rarely if ever used. Oral and blood samples are far more likely to be used for HIV testing.

What does a positive RPR blood test mean?
RPR test, syphilis test The rapid plasma reagin (RPR) test is a blood test that looks for antibodies to syphilis. In addition, people who have early-stage syphilis may have sores (lesions).

How to interpret RPR?
Interpretation of RPR Test. Non-reactive (NR) – smooth suspension, no clumping or slight roughness; Reactive (R) – any degree of clumping; If the test is negative, but the physician still suspects the infection is present, the more specific treponemal tests (FTA-ABS, MHA-TP, TPHA etc.) should be performed. False positive results
