Interpretive Data: The syphilis IgG screen is an entirely new method relative to the RPR (rapid plasma reagin). The RPR detects non-treponemal antibodies (cardiolipin, cholesterol, and lecithin), whereas the new test detects IgG antibodies to T. pallidum proteins (15 kDa, 17 kDa, 47 kDa). The new approach to syphilis is termed 'reverse algorithm' in that RPR is not done as first test (traditional algorithm) but as the confirmation (i.e., reverse of the traditional algorithm). A negative syphilis IgG means that past and present syphilis infection is unlikely. A positive syphilis IgG can indicate a past or present infection.
