Introduction This user manual is intended as a guide to the service and tests available from the Greater Glasgow and Clyde (NHS GGC), Histocompatibility and Immunogenetics (H&I) Service. It provides details of the test repertoire and the specimen requirements. Revision 8, Issued December 2012 Page 3 of 30
A) Laboratory scope and location The field of H&I is a consultant-led specialist discipline represented in the UK by the British Society for Histocompatibility and Immunogenetics (BSHI). The H&I Laboratory (historically referred to as Tissue Typing) is located within Gartnavel General Hospital (GGH) part of NHS GGC. The service was originally located at the Glasgow Royal Infirmary until May 2008 when an organisational move to purpose built laboratories at GGH was undertaken. These laboratories provide state of the art containment rooms to facilitate genetic and cellular testing and analyses. The H&I laboratory is part of the Diagnostic Services division of NHS GGC and provides a comprehensive range of serological, molecular and cellular techniques. These tests aim to identify human leukocyte antigens (HLA) and to detect immunological sensitisation to HLA. Supporting the first renal transplant to be performed at the Glasgow Royal Infirmary in 1968, the laboratory has evolved to support both solid organ and Haematopoetic progenitor cell transplantation (HPC) programs operating locally, nationally and internationally. In addition the laboratory provides HLA testing to aid disease diagnosis and supports pharmacogenetic studies. Laboratory scientists (healthcare scientists) are Health Professions Council (HPC) registered and undertake continuous professional development in order to maintain and develop their specialised technical and scientific skills. The laboratory is accredited by Clinical Pathology Accreditation (CPA) and by the European Federation for Immunogenetics (EFI). Revision 8, Issued December 2012 Page 4 of 30
H&I tests are carried out in support of: supra-regional solid organ transplantation, (kidney and heart); haematopoietic progenitor cell transplantation (related and unrelated donor); platelet transfusion (in liason with the local Scottish National Blood Transfusion Service, SNBTS, H&I laboratory); disease diagnosis, (e.g. Narcolepsy; Ankylosing Spondylitis; Coeliac disease; Behçet s disease); pharmacogenetics (abacavir hypersensitivity) Immunogenetic polymorphism analysis is also utilised to aid determination of the immune status in: immunodeficiency disorders, autoimmune disease, vascular disease and transplantation immunology. The majority of test requests are received through secondary and tertiary referrals although direct access from primary care groups also occur. Revision 8, Issued December 2012 Page 5 of 30

F) Sample Requirements Information regarding sample request forms is available from the laboratory. The laboratory operates strict criteria for the acceptance of, and for the processing of patient samples. These criteria are necessary to ensure that the correct results for the correct patient are reported to the appropriate person. It is in the interest of the patient and medical practitioner to get this stage of the process correct as subsequent quality stages are inconsequential should the sample be from the wrong individual. Please note Asterisk * indicates mandatory information the blood sample may not be tested and/or reported if these fields are not completed accurately. Specimen *Name Hospital and ward *CHI number (for samples originating in Scotland) *Date sample taken Request form *Name *Date of Birth *CHI number (for samples originating in Scotland) *Hospital and ward *Consultant/requester to whom the report is to be issued *Date sample taken *Clinical details/ diagnosis Both specimen and request form information MUST agree. If there is a discrepancy this will delay processing and turnaround times Revision 8, Issued December 2012 Page 19 of 30
Additional Paperwork that may accompany specific samples 1 Renal patient to be registered on deceased donor transplant list Completed yellow activation form should include details of previous sensitising events i.e. pregnancy and /or transplant and/or transfusion Date commenced dialysis Virology Information (CMV etc) Copy of original blood group reports from testing of two independently drawn blood samples 2 Patient to receive a haematopoietic progenitor cell (HPC) transplant from a volunteer unrelated donor (VUD) Patients for potential HPC transplant must have a VUD referral form submitted (VUDRF BMT 103 025) if a VUD search is to be instigated. CMV status, blood group and patient weight must be included. Please note that as soon as a patient presents with a condition that may at some stage in the future require HPC transplant, then an EDTA sample should be forwarded to the laboratory. This will help prevent unnecessary delay and maximise the efficiency of the registry searches for an unrelated donor when the time arises. 3 Local Deceased donors Copy of blood group report Coordinators details to be given on sample request form Revision 8, Issued December 2012 Page 20 of 30
Packaging of diagnostic samples All diagnostic samples must be packaged in containers compliant with UN packaging instruction P650. All packages must be labelled as shown below. Biological Substance Category B Information with regard to high risk specimens (e.g. HIV or Hep B/C status) should be clearly marked on BOTH sample and request form. Labels indicating high risk will suffice. Revision 8, Issued December 2012 Page 21 of 30
G) Transport of specimens Specimens should be sent in the sealable bag attached to the yellow H&I (Tissue Typing) request form. Specimens at the GGH site are delivered via local arrangements. All other specimens must be transported by van or taxi or sent by Post (observing postal regulations). Check with your local organisation. Only specimens referred from authorised medical practitioners can be processed. Patients can not self-refer. HLA typing (EDTA) and antibody analysis (clotted) samples EDTA samples and clotted samples are stable at ambient (22 C) temperature for 4 days. Crossmatching Samples - DO NOT REFRIGERATE! Crossmatch Samples (EDTA (20mls) and Clotted (10mls)) should be received within 24 hours of venesection. Please book crossmatch in advance by contacting the laboratory. Urgent deceased donor samples Samples (EDTA peripheral blood, spleen, lymphnode) from deceased donors can be sent directly to the laboratory within working hours (8.00am to 4.30pm). Please notify the laboratory of expected arrival time. Outwith the above hours, deceased donor samples should be forwarded to the porters desk at the main entrance to GGH which is manned 24 hours. Also inform the on-call tissue-typist of their arrival 0141 211 3000. Revision 8, Issued December 2012 Page 22 of 30
Urgent antibody screening samples This requires agreement with the laboratory to confirm that the urgent testing can be performed. The samples must be sent by taxi and arrive within the agreed time frame. At present this service is not available out of hours except by arrangement between the requesting consultant and a senior member of the laboratory staff (Laboratory Director, Laboratory Manager or Deputy Manager).

Notes Blood grouping requests should be sent to local or central blood transfusion service. The H&I lab does not test for blood groups Clotted samples from HPC patients are tested for HLA antibody and sent to the virology laboratory for CMV testing Molecular HLA typing involves the extraction of DNA from blood or tissue samples. If the patient has a low WBC count then this information should be conveyed to the laboratory. Non blood samples e.g. amniotic fluid and mouth wash preparations are not routinely processed, therefore prior arrangement with the laboratory is essential. Revision 8, Issued December 2012 Page 25 of 30
I) Reporting of results Hard copy reports are computer generated from the controlled laboratory patient management system. A paper copy of each report is printed, signed by designated staff and dispatched by internal hospital mail. Faxed Reports Faxing of reports that include patient name and personal information are covered under data protection act and has been prohibited by The Scottish Government. FAX results will only be permitted between secure fax machines. Email copy of authorised reports Reports can only be sent between secure email addresses e.g. nhs.net to nhs.net and ggc.scot.nhs.uk to ggc.scot.nhs.uk Oral transmission of results In order to prevent sensitive or incorrect information being released to inappropriate persons the oral transmission of results is actively discouraged. Only in an emergency or in the acute setting will an oral authorised report be issued by a senior member of staff to a suitably qualified person. The result will be verbally repeated by the recipient to ensure the accuracy of the communication. A hard copy report will follow ASAP. Revision 8, Issued December 2012 Page 26 of 30
