Vdrl Blood Test

The full form of the word VDRL is Venereal Disease Research Laboratory test. The VDRL blood test is been tested for the determination of syphilis. The VDRL type test was first used before 1st World War, with its first iteration being developed by August Paul von Wassermanwith the help of Albert Neisser in the year 1906.The test is usually performed on blood, it can be also performed on spinal fluid when syphilis (neurosyphilis) can be present in patient’s brain. The test does not give a hundred percent accuracy. An unfavorable (nonreactive) VDRL is congruous with an organism not having syphilis, but in the precocious stages of the disease, the VDRL often gives fictive unfavorable results.

Conversely, an insincere affirmatory VDRL can be encountered in contaminating antiphospholipid antibody syndrome, leprosy, malaria, infectious mononucleosis lupus, hepatitis A, occasionally pregnancy. The VDRL test is something which measures the antibodies called ‘reagin’ that might be created by Treponema pallidum, those bacterias which are the main reason of syphilis. However, the body doesn’t continuously create antibody especially in reaction to the syphilis bacteria, that’s why the test is not always measures accurately. A nonreactive VDRL is well-matched with a being not having syphilis. Syphilis is a sexually transmitted disease (STD) that is usually dispersion during unisexual conjunction, including kissing or viva sex.

Various states also enjoin screening for syphilis antecedent to obtaining a marriage license. The VDRL test is not very useful for detecting syphilis in very early or advanced stages. The other tests used for determining sphillis are Rapid plasma reagin (RPR) test, Enzyme immunoassay (EIA) test, Fluorescent treponemal antibody absorption (FTA-ABS) test, Treponema pallidum particle agglutination assay (TPPA) etc.
