Ordering HLA selected components

Core laboratory hours

Monday to Friday, 9am to 5pm (excluding bank holidays).

New requests for Human Leukocyte Antigen (HLA) selected platelets

Hospital staff must first phone their H&I laboratory to discuss patient information and testing and component requirements. An order form (FRM 558) will be faxed to the hospital by the H&I laboratory. The completed order form should be faxed back to the H&I laboratory. This form is not available on the website to ensure this essential process is followed.

Second and subsequent orders

For named patients who have previously received HLA selected platelets, please use OBOS (Online Blood Ordering System) to order specialist stock (HLA and HPA products). Orders for emergency requests and planned procedures can be placed via OBOS.

To ensure the best matched product is provided for your patient, please place orders on OBOS for planned procedures at least 24 hours in advance of the required delivery time, Monday to Friday.

Please refer to the OBOS user guide for guidance on how to order products.
