Method of Analysis: cPRA determinations are determined with the CBS cPRA calculator and are based on specificities detected with solid phase bead technology using the Luminex® platform.
Critical Information Required: DSA analysis requires knowledge of the HLA typing of the donor or prospective donor of interest. Patients who were not transplanted in the London program will need to have this information forwarded to this laboratory.
Storage & Shipment: Samples drawn at LHSC are delivered to the Transplant Laboratory at room temperature.

Samples for Antibody Testing (1 red top) drawn outside of LHSC must be spun and the serum removed and frozen. Ship on dry ice if shipping requires >24 hours. Ship frozen on freezer packs if the sample will be received in < 24 hours.
