Synthetic VDRL Antigen Test

The ASI Synthetic 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.

This environmentally friendly ASI Synthetic VDRL is manufactured exclusively by Arlington Scientific in the USA.  For more than a decade, Arlington Scientific has worked closely with the Centers for Disease Control and Prevention to provide CDC-licensed Synthetic VDRL. Our ASI product is FDA cleared and is substantially equivalent to traditional VDRL manufactured by other companies.

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.
