The ASI VDRL Antigen Test is a nontreponemal test used for the screening of syphilis. VDRL is a specific qualitative (Positive or Negative) and semi-quantitative test (concentration of) that detects reagin antibodies (proteins), in human serum. This VDRL test can also be used to detect if syphilis has involved the central nervous system (Neurosyphilis) by testing cerebral spinal fluid.
Kits include two vials of VDRL antigen (2 x 5mL), two vials of VDRL buffered saline (2 x 60mL). The kit could perform as many as 5,900 tests but it is generally less due to facility testing workflow.
