nontreponemal and treponemal, will be negative. Treatment in the primary or secondary stage usually results in a rapid decline in the RPR antibody titer, frequently to non-reactive in 6-18 months. Treatment given in the tertiary stage
If an RPR test comes back as abnormal, a quantitative titer test will then be performed to determine the actual concentration of antibodies in the blood sample. If the titer returns a ratio of 1:4 or higher, the CDC then recommends doing a T. Padillum test because both types of tests ...
All reactive serum requiresserial dilutionto estimate antibody titer. The titre is reported as the reciprocal of the highest dilution, which shows a positive test result. When the quantitative RPR card test is performed on patients with syphilis, a fourfold rise in titer in a repeat specimen may...
The median serum RPR titer was significantly higher in CSF RPR+ patients than that in CSF RPR- GP patients, 1:8 [IQR 1:4–1:32] vs. 1:4 [IQR 1:4–1:8] (P < 0.001). The number of CSF RPR+ patients with serum RPR titer≥1:32 was significantly higher when compared with ...
结果:观察组血清RPR滴度<1:8者所占比例为95.12% (39/41),高于对照组62.50% (25/40),差异具有统计学意义(P<0.05);观察组不良妊娠结局发生率为7.32% (3/41),低于对照组25.00% (10/40);足月儿所占比例为92.68%(38/41),高于对照组75.00%(30/40),差异具有统计学意义(P<0.05);观察组新生儿不良结...
RPR test is readily available in kit form, does not require a microscope, and its titer can be used to monitor the progression of the disease. It is also cheap and an effective screening test. VDRL test is simple and rapid, cheap, helps diagnose congenital syphilis, and is fast and easy...
(before chancre formation) will usually completely suppress antibody formation and all serological tests, nontreponemal and treponemal, will be negative. Treatment in the primary or secondary stage usually results in a rapid decline in the RPR antibody titer, frequently to non-reactive in 6-18 ...
