[About effectiveness and perspective of application of test of venereal disease research laboratory (VDRL) for diagnostic of neurosyphilis in the Russian Federation].

The comparative evaluation of effectiveness of different nontreponema tests in analysis of cerebrospinal fluid. The liquor from 100 patients with syphilis was analyzed using Bordet-Gengou test, VDRL test and micro-precipitation reaction with cardiolipin antigen. The Bordet-Gengou test and VDRL test made in Russia or abroad are equally effective in analysis of positive samples of liquor and twice surpass the same capacity of micro-precipitation reaction with cardiolipin antigen in case of neurosyphilis with symptoms and thrice surpass in case of asymptomatic neurosyphilis. VDRL test is a simple standardized nontreponema reaction which can substitute labor-consuming non-unified liquorologic complex in laboratory diagnostic of neurosyphilis. The testing of liquor on the basis of micro-precipitation reaction with cardiolipin antigen is non-effective and results in false negative results in Bordet-Gengou and VDRL positive tests determining high risk of erroneous clinical considerations.
