Sample Labelling
Please label samples clearly with hospital number, first and last name and date of birth using a ballpoint (permanent/indelible) ink pen. The NHS number may be used in place of the hospital number for GP and non-UCLH Trust patients.
Samples for a Group and Save (including an antibody screen) and Crossmatching must be hand written with four correct points of ID. Sticky labels are not permitted. Please include the time and date of collection and the signature of the person collecting the sample.
A minimum of three points of identification must be provided for all other samples.
NOTE: Samples received broken/leaking, inadequately labelled, aged, clotted, haemolysed or otherwise unsuitable for testing will not be processed; an appropriate comment will be entered onto the computer system. If the requested tests are urgent, laboratory staff will attempt to notify the ward/clinician.
Sample Transport to the Laboratory
Refer to the Pathology Specimen Transport policy on the UCLH Intranet for hospital transport.
Samples from GP practices must be sent via UCLH Trust transport; via the next available collection during the working day. If a significant delay in sample transportation to the laboratory is anticipated, please discuss with laboratory staff, as sample deterioration may limit the viability of results.
Special Handling Requirements
Please see the ‘Notes’ section in the test tables below, or contact the relevant laboratory for information regarding special handling requirements.

Requests for routine (scheduled) surgery
Requests must be received in the laboratory by 1900hrs on the day before surgery. A positive antibody screen will delay completion of testing and provision of compatible units. Patients with known antibodies must be followed up within an agreed time-frame prior to surgery according to their pre-admission group and screen report.
Samples received after this time will be prioritised by order of the theatre list. Emergency cases will take priority.
Where Remote Issue is not available, requests for routine surgery should comply with the local Maximum Surgical Blood Ordering Schedule (MSBOS). Refer to the Trust Blood Transfusion Manual on the intranet.

Transport of Routine Blood and Blood Products
Remote issue of red cells has been implemented at UCLH. This allows blood to be issued directly from the Remote Issue blood fridge at the point of care, rather than from the laboratory for most patients. A small percentage of patients will still need blood crossmatched by the laboratory but this can also be stored in the remote issue blood fridge and dispensed when required. FFP for patients will be sent to remote issue fridges by the laboratory and dispensed in the same way. Cross matched blood for patients with special requirements and those not eligible for remote issue and other blood products are dispatched as follows:
Non-urgent blood and blood products are dispatched from the laboratory at various times during the day.
Urgent blood and blood products are dispatched from the laboratory by courier (arranged by the laboratory). PLEASE CONTACT THE LABORATORY
(x78523/78522 during routine work hours or Bleep 7060 out of hours) IF BLOOD IS REQUIRED URGENTLY.
*FFP will be returned to the laboratory 24 hours after it has been thawed.
*Unused platelets/FFP/Cryoprecipitate are withdrawn the day after the original date required.
Cryoprecipitate should be used within 4 hours of thawing and any remaining units returned to the lab.
*If the product is no longer required, contact Blood Transfusion immediately. This can reduce blood component wastage if the units can be re-
issued to a different patient before the expiry time.
Always ring the laboratory before use of EMERGENCY UNCROSSMATCHED BLOOD*

All other times:
General Haematology Registrar via UCLH switchboard
Discuss: Appropriate treatment (If a high risk procedure, or the patient has a known coagulation abnormality, contact the Haemostasis Registrar prior to procedure and discuss the patient’s management)
Monday →Friday 09:00 – 17:00
Haemostasis Registrar UCH Bleep 7044/7000

3. Indications for the transfusion of red cells, FFP, cryoprecipitate and platelets
Please refer to the relevant chapter/appendix in the Trust Blood Component Transfusion Procedure Manual http://insight/guidelines/Clinical%20guidelines/Blood%20Transfusion%20Manual%202012.pdf
4. Patients with Special Transfusion Requirements For patients who may require CMV negative blood products, Irradiated blood products, Washed red cells and/or HLA matched platelets:
Please refer to the relevant appendix in the Blood Component Transfusion Procedure Manual. Ensure that the laboratory has received a Blood Transfusion Status Form by emailing BT Status or by faxing to fax number 0203 447 9587 before requesting blood products (this form can be downloaded from the Blood Transfusion site on the UCLH intranet).

Paediatric citrated tubes are issued from the Haemostasis Laboratory to the Neonatal Unit, Paediatric A&E and Phlebotomy Outpatient departments and can be issued to other locations on request: contact x78549/78545 during routine hours.
Include clinical details on the request form, e.g. “patient receiving Warfarin/Heparin therapy” or “post op”; to facilitate appropriate testing and interpretation of results.
Send the request form and sample to the laboratory as rapidly as possible; notify the laboratory regarding very urgent requests on ext 78547 (during routine working hours) or Bleep 7060 (out of hours).
Grossly lipaemic samples may require manual testing, potentially delaying results.
