Comparison of results of 3 tests showed that out of 100 sera, 85 sera were VDRL reactive and RPR test
was in 84 sera.
The RPR test
result was reactive at a dilution of 1:16, and a T pallidum particle agglutination confirmatory test result was reactive.
To contribute to the scant data on syphilis screening and prevalence in psychiatric patients, we aimed: (i) to determine and compare the prevalence of syphilis among different psychiatric inpatient groups; (ii) to determine and compare the psychiatric diagnoses of syphilis-infected and -uninfected patients; (iii) to assess self-reported high-risk sexual behaviour among patients; (iv) to establish the syphilis/HIV co-morbidity among patients; (v) and to investigate the performance of the non-treponemal RPR test
as a screening method compared with the confirmatory treponemal-specific TPHA test.
Of all 6,548 specimens reactive to the treponemal EIA test and then tested using an RPR test
, 44% were reactive and 56% (3% of the overall sample) non-reactive with an RPR test
3) The RPR test
is of particular interest in our case because although our patient exhibited many of the characteristic findings of secondary syphilis, his initial screening test for syphilis yielded a false negative as a result of the prozone phenomenon.
In general, asymptomatic detainees are not required by law to submit to the RPR test
The RPR test
suite allows users not only the flexibility of generating, analyzing and capturing both Data and Control packets exchanged between nodes within an RPR ring environment, but the additional advantage of being able to manipulate and configure the contents of the packets to test a myriad of ring scenarios.
7) RPR test
titer >4/TPHA titer >80, ([dagger]) % 1.
At a third laboratory, specimens that were reactive to both the EIA test and the RPR test
were retested using a different treponemal test (i.
