Completion of the request form

Please use the appropriate request form for the tests required and ballpoint (indelible) ink pen to complete the form.

• Please provide the patient’s full name, hospital number and date of birth.

• Please provide the date and time of sample collection and relevant clinical information to facilitate sample processing and the interpretation of results.

• Please use a separate Blood Transfusion request form for Blood Transfusion requests; Group & Save, Crossmatch, Kleihauer, DAT.

• Please ensure that the destination of the report, the name of the requesting/responsible clinician and a contact bleep/telephone number for the responsible clinician is provided to enable laboratory staff to notify the clinician regarding unsuitable (urgent) samples and to relay and/or discuss urgent or grossly abnormal results.

• Please tick the box next to the test(s) requested; if a required test is not listed, write it clearly into the “Additional Tests” section.

• Please tick the appropriate box when the patient is anticoagulated (on warfarin or heparin).

• If possible please provide clinical details.

Please ensure that adequate samples are taken for the tests requested and that each sample is labelled correctly. Contact the relevant laboratory for clarification of sample requirements if required.

Sample Collection (phlebotomy)

The sample collection policy for staff trained in phlebotomy [Haem-PD-BloodSampColl] and guidelines for sample labelling are available on the UCLH Intranet and can be sent electronically to GP practices.

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. 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

UCLH samples: refer to the Pathology Specimen Transport and Pneumatic Tube System policies 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 • Samples received after this time will be prioritised by order of the theatre list. Emergency cases will take priority. • 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.

*Always ring the laboratory before use of EMERGENCY UNCROSSMATCHED BLOOD*

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).

• Citrated samples must be adequately filled (a 9:1 blood:citrate sample ratio is required for all citrated samples). Tests cannot be performed on underfilled, overfilled, haemolysed or clotted samples.

• 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. • Abnormal results that require further laboratory investigation and/or manual testing/confirmation may be delayed.
