ASI VDRL Antigen Test

The ASI VDRL Antigen test for syphilis is a specific qualitative and semi-quantitative nontreponemal flocculation test for the detection of reagin antibodies in human serum. The procedure is based on the VDRL antigen being combined at a correct ratio with buffered saline and then mixed with heat-inactivated serum.

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.
