Both murine and human myeloma proteins have been shown to have antibodylike activity for serum lipoproteins. We studied a 58-yr-old woman (M.L.) with a lymphoma and a VDRL titer of 1:4096 and a nonreactive FTA-ABS. Serum electrophoresis revealed an M-component which was shown to be 1gM-kappa by immunoelectrophoresis and 2-mercaptoethanol treatment of the serum reduced the VDRL titer to 1:64. Im...

This study evaluates the American Dade (Biokit Laboratories) rapid plasma reagin (Dade RPR) card test, currently used in Spain for the diagnosis of syphilis, which has been recently released to the U.S. market. Used as a basis for comparison with the Dade card test were the 18-mm standard rapid plasma reagin (standard RPR) card test and the Venereal Disease Research Laboratory (VDRL) slide test...

We evaluated analytic performances of an automated treponemal test and compared this test with the Venereal Disease Research Laboratory test (VDRL) and fluorescent treponemal antibody absorption test (FTA-ABS). Precision performance of the Architect Syphilis TP assay (TP; Abbott Japan, Tokyo, Japan) was assessed, and 150 serum samples were assayed with the TP before and after heat inactivation ...

In an earlier paper in this Journal (Vogelsang, 1947), a new microflocculation test for syphilis described by Harris, Rosenberg, and Riedel (1946) was compared with the Wassermann reaction, the Kahn standard test, and the Meinicke clarification test in 5,556 sera. The test was found to be very useful in the diagnosis of syphilis, having a satisfactory sensitivity and a good specificity. Harris ...

A survey has been made of the results of 12 months' VDRL screening in a blood transfusion service. Positive VDRL tests were found on 318 of the 73 350 blood donations collected during 1974. Thirty-four tests confirming specific treponemal infection were found in 24 donors. A battery of confirmatory tests showed the remaining 284 positive VDRL reactions from 235 donors to be biological false pos...

OBJECTIVE To determine the seroprevalence and cost effectiveness of antenatal syphilis screening at the University of Maiduguri Teaching Hospital (UMTH), Maiduguri, Nigeria. METHODS A retrospective chart analysis of venereal disease research laboratory (VDRL) results among pregnant women at the UMTH, Maiduguri, Nigeria, during a 10-year period (from 1st January 1999 to 31st December 2008) was...

A total of 19,067 sera were screened for biological false positive (BFP) reactivity by the Venereal Disease Research Laboratory (VDRL) test. Sera which were reactive in the VDRL test were confirmed by the fluorescent treponemal antibody absorption (FTA-ABS) test. BFP reactions were detected in 0.59% of the general population, 0.72% of pregnant women and 11.8% of patients with systemic lupus ery...
