What is the RPR test project?

RPR test is a serological test for screening syphilis.

Syphilis serum test is a diagnostic test for syphilis. According to the different antigens used, syphilis serum tests can be divided into the following two categories:

1, non-treponema pallidum antigen serum test, using cardiolipin as antigen, the anticardiolipin antibody in serum is determined, also known as reagin.

2. Treponema pallidum antigen serum test: using live or dead Treponema pallidum or its components as antigen, the anti-Treponema pallidum antibody is determined.

Extended data:

Non-treponema pallidum antigen serum test, using cardiolipin as antigen, determines anticardiolipin antibody in serum, also known as reagin. This test has high sensitivity and low specificity, and it is easy to appear biological false positive. At present, it is generally used as screening and quantitative detection to observe the curative effect, recurrence and reinfection.

1, STD research laboratory testing; Using cardiolipin, lecithin and cholesterol as antigens, it can be used for quantitative and qualitative detection. The reagent and control serum have been standardized and the cost is low. This method is commonly used and simple to operate, and the results need to be read by microscope. The disadvantage is that the sensitivity of primary syphilis is not high.

2. Rapid plasma reagin test: The sensitivity and specificity of the improved VDRL antigen are similar to those of VDRL, with the advantage that the results can be read by naked eyes.

3. Unheated serum reagin slide test: The sensitivity and specificity of VDRL antigen are similar to VDRL.
