HelpTest Code Irradiated Blood Products Irradiated Blood Products
Useful For
Products are exposed to a gamma irradiation source to prevent graft-vs-host disease.
Irradiation prevents the proliferation of transfused T lymphocytes in the recipient.
Must have an acceptable specimen drawn less than 72 hours for RBCs. Plasma and platelet products only require a blood type to be on file in Transfusion Service.

Collection/Processing Instructions
For crossmatched RBCs: Must have an acceptable specimen drawn less than 72 hours before crossmatch.
For CLINIC patients where Hand-Held device is used for label generation: Patient must be arm banded with SCANID label. Specimen label must have the patient's complete first and last name, printed medical history number, date of birth, and specimen collection date and time.
For HOSPITAL patients where Hand-Held device is used for label generation: Patient must be arm banded. Specimen label must have the patient's complete first and last name, printed medical history number, date of birth, and specimen collection date and time.
If performing the collection without the use of the Hand-Held system:
CLINIC patient must be armbanded (arm band to include medical history number, first and last name, date of birth, collection date), specimen label must have the patient's complete first and last name, printed medical record number, handwritten medical record number, specimen collection date and time, date of birth, and phlebotomist initials.
For HOSPITAL patients, patient must be armbanded, specimen label must have patient's first and last name, printed medical history number, handwritten medical history number, specimen collection date and time, date of birth, and phlebotomist initials.

Test Information
Products are exposed to a gamma irradiation source to prevent graft-vs-host disease. Irradiation prevents the proliferation of transfused T lymphocytes in the recipient. Any patient identified as requiring irradiated blood products must have a written physician request and a blood bank test request written to have "All Blood Products Irradiated." When irradiation is no longer required, a blood bank test request is required to end-date the Special Need in Transfusion Service. Irradiated Platelets Red Blood Cells are therapeutic products. Send a completed Blood Bank request form specifying the number of units needed to the Blood Bank and mark the irradiation need. Red Blood Cells must be crossmatched prior to release. Allow an additional 10 minutes for irradiation of blood products. A blood type and antibody screen are performed prior to crossmatching the irradiated red cell. Crossmatches are performed before administration of whole blood and all packed red blood cells to determine compatibility between donor cells and recipient plasma. Blood specimen will be held for 72 hours pending crossmatch orders.
