The Transfusion Medicine Department is part of the St James’s Hospital Centre for Laboratory Medicine and Molecular Pathology and provides blood and blood products for the hospital’s inpatients.
We also perform blood tests including ABO/Rh typing, antibody screening, antibody investigation, cross matching and direct Coombe tests.
Traceability of all blood products is essential and our Haemovigilance department ensures this is carried out.

On-call Laboratory (Out of hours)
The Department of Transfusion Medicine including Haemovigilance provides support to all the clinical specialities in the hospital. We provide a 24 hour service 7 days a week.
This service includes blood grouping, antibody screening, antibody investigation, direct Coombs test, cross matching and issuing of blood, blood products and blood components including frozen plasma, platelets, fibrinogen, Anti-D, coagulation factor concentrates and albumin.
Haemovigilance, in collaboration with the Transfusion Medicine Department and other blood users through the Transfusion Committee contribute to the delivery of best practice transfusion service including monitoring and traceability of blood/blood component use. The Haemovigilance department has an important role in many transfusion practices including investigation and reporting of adverse events and reactions.
There is a consultative service, for both laboratory and Haemovigilance issues, available to users 24 hours a day. This is led by the Consultant in Transfusion Medicine.
The Health Professionals involved in Transfusion Medicine include:

The Department of Transfusion Medicine including Haemovigilance of St James’s Hospital was initially awarded accreditation by the Irish National Accreditation Board (INAB) on 28th October 2008 as being in compliance with ISO/IEC/15189. The scope of the accreditation is detailed under Registration Number 327MT.
It is also competent to comply with articles 14 and 15 of the EU Directive 2002/98/EC (S.I. No. 360 of 2005 and S.I. No. 547 of 2006).
There is a legal obligation on all hospital blood banks to be able to trace all units of blood and blood products from receipt to final fate. To comply with this St James’s Hospital introduced a tagging system of labelling blood packs. The pink peel off section must be placed in the patient's chart and tear-off section must be completed and returned to blood transfusion.
This legal obligation extends to reporting all Serious Adverse Reactions (SARs) and Serious Adverse Events (SAEs) to the National Haemovigilance Office.
Serious Adverse Reaction:
An unintended response in the patient associated with the collection or transfusion of blood and blood component that might:
Serious Adverse Event:
Any untoward occurrence associated with the collecting, testing, processing, storage and distribution of blood and blood components that might:
Any such reaction or event should be reported to the Blood Transfusion Department.
Routine Requests e.g Group & Hold or Crossmatch
Samples stored at 18 - 25oC for up to 48 hours are suitable for processing.
A completed request form (PCO2) or a Group & Hold/Crossmatch request on EPR and a correctly labelled sample must be forwarded to Blood Transfusion.
If the laboratory has a valid sample, an EPR request accompanied by a phoned confirmation is acceptable for blood and blood product requests. For internal users, a link to the instructions on using the EPR can be found in the Education and Resources section of the Blood Transfusion Departments webpage.
Blood Transfusion sample labelling requirements are very strict.
For internal SJH users, see acceptance/rejection Criteria for sample and request cards or refer to the clinical information section of the Blood Transfusion Department's webpage.
For external users, the minimum sample/request card labelling criteria are: Surname, Forename, DOB, Date and time of sampling and signature.
Number of units required
Date and time required
Reason for transfusion
Name of requesting medical doctor.
The Medical Doctor must phone the Laboratory (2989, 2958 or 2945) explaining the urgency.
Group and Hold (urgent) can take 1 hour 15 mins.
Group & Crossmatch can take 1 hour 30 mins.
Crossmatch on a sample that is already on Group & Hold (Antibody Screen Negative) can take up to 30 mins.
If the antibody screen is positive there is increased delay in providing blood.
Any delays in the provision of Blood or Blood Components will result in the Clinical Team being notified.
Life Threatening Emergencies / Code Red situations
'Code Red’ is the alert used in St James’s Hospital to advise the Blood Transfusion Laboratory of life threatening bleeds.
Emergency O Rh(D) Negative units are held in the Burns Unit fridge, Theatre fridge and ICU fridge for use in life threatening emergencies.
Emergency Plasma and Emergency PCC are held in the Burns Unit fridge for use in life threatening emergencies.
Sending the sample to Laboratory
Place sample in an appropriate biohazard plastic bag and send via the Pneumatic Tube System (PTS) or via portering services for urgent samples.
Clinical Advice and Interpretation
Scientific advice and interpretation is available from blood transfusion scientific staff. Clinical advice is available from the Consultant in charge of blood transfusion including haemovigilance or out of hours from the consultant haematologist on-call.
Referral Laboratory Details
Patient specimens may be referred to external laboratories for a number of reasons. These include complex antibody combinations, patients with auto antibodies, and people with weak blood groups which need to be confirmed.
A Service Level Agreement exists between the Irish Blood Transfusion Service (IBTS), National Blood Centre, James’s St., Dublin 8. and St James’s Hospital.
The blood transfusion dept. has access to the External Quality Control results of the IBTS.
Time Limits for Requesting Additional Examinations
Samples are retained for one month. Additional products can be requested by telephone and EPR. A new sample may be required if the patient has been transfused in the previous three months or is currently pregnant
Two types of reports are issued by Blood Transfusion. All blood components and blood products issued are labelled with a 'Compatibilty Tag'. The tag has a peel off portion which is attached to the patient's medical chart if product is transfused.
The tag contains the following information
For internal SJH users all reports are now reported on the EPR (Blood Transfusion section). This includes DCT reports previously reported on EPR(haematology section).
Printed reports are provided to external users and can be provided, on request, to internal users.
When required for clarification, descriptive comments are added to the report.
An amended report is a report that is changed in any way after the initial report has been authorised and issued. This is required following e.g. a change in patient demographics, post additional testing or if blood product details have to be amended. The amended report detailing the changes made (and original report) are available on the EPR.
