Nontreponemal tests are screening tests, very rapid and relatively simple, but need to be confirmed by treponemal tests. [1] Centers for Disease Control and Prevention (CDC)-approved standard tests include the VDRL test (a slide test), the rapid plasma reagin (RPR) test (a card test), the unheated serum reagin (USR) test, and the toluidine red ...
The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).
The Venereal Disease Research Laboratory test (VDRL) is a blood test for syphilis and related non-venereal treponematoses that was developed by the eponymous US laboratory. The VDRL test is used to screen for syphilis (it has high sensitivity ), whereas other, more specific tests are used to diagnose the disease.
Syphilis is typically spread through direct contact with a syphilis sore, known as a chancre, during vaginal, anal or oral sex. It can also be passed from a pregnant person to a child during birth.
Aug. 20—Amid a local and national surge of syphilis, the U.S. Food and Drug Administration this month approved an over-the-counter test for the sexually transmitted infection. While some may ...
The new test received FDA authorization after the company submitted data from clinical trials showing that the First To Know Syphilis Test identified a positive specimen 93.4% of the time.
The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
Often a plastic test plate containing many small "wells" is used as the test dish so that many patients may be tested at the same time but their results can be kept separate from each other. Please note the image (Fig 1) of the wells on the test plate and the positive and negative test results look different. [1] For primary syphilis, TPPA has ...
