A Syphilis/VDRL (Venereal Disease Research Laboratory) Strip is a diagnostic test device used to detect the presence of antibodies in a patient's blood or serum that are specific to Treponema pallidum, the bacterium responsible for syphilis. The VDRL test is a non-treponemal test used for the screening of syphilis, and it can be performed using various formats, including strips or cards.
