Blood & blood products

Crossmatched blood

Crossmatched blood is held in the Issue Fridge in Pathology at the respective sites. The blood bank register must be signed for all units collected from the Issue Fridge. Personnel collecting blood components must bring with them blood collection slips. At PRH these are filled in by the ward staff or porters. At RSCH the porters fill in the details.

The collection slips must have the details of the patient for whom the blood component is required. The collection slips are returned to the ward and a nurse must sign that the unit of blood has been received on the ward. Crossmatched blood is reserved for 24 hours, from the date required.

Traceability slips

These must be completed and returned to the respective transfusion laboratory immediately after transfusion. The EU blood Directive states that their must be vein to vein traceability of blood and blood products. Failure to complete and return the traceability slips is in breach of the EU Directive.

Blood storage

Blood must be kept at 2-6°C in designated blood fridges. Under no circumstances must it be stored in domestic fridges. Blood that has been out of the blood fridge for more than 30 minutes with no imminent prospect of transfusion must be returned to the laboratory for disposal. Blood returned within 30 minutes must be placed in the blood fridge and the blood bank register completed with the time and date of return and the signature of the person returning it. Laboratory staff must be made aware of out of temperature controlled units of blood.
