The main purpose of this Manual is to provide useful guidelines for the selection of pathology tests and to facilitate interpretation of results.
Contains a comprehensive listing of all genes from the Human Gene Nomenclature Committee (HGNC) database alongside laboratories and tests available in the country.
A manual for the process of macroscopic dissection in Anatomical Pathology laboratories.

10 mL blood in plain tube; for some methods, blood in EDTA is preferred.
Patient's identity must be positively confirmed at time of sample collection (that is, asking the patient to state surname, given names and date of birth and check ID labels are fastened to the patient's wrist). Three approved patient identifiers (eg, surname, given names (in full), record number or date of birth) and date and time of collection, and signature or initials of collector are required.
Blood group and serum antibody screen performed; ABO and Rh(D) matched donor blood selected.
Recipient serum tested against donor red cells by indirect antiglobulin test and one other technique (eg, saline, Polybrene, enzyme).
Crossmatch may be replaced by an immediate spin compatibility test if the recent blood group antibody screen is negative.
See also Blood group and Blood group and antibody screen.
Selection of compatible blood for transfusion.
Details of specific transfusion requirements, including date of procedure, urgency of requirement and patient location is required for the laboratory.
Refer to the laboratory for details of the duration of validity of the routine cross-match specimen.
Compatibility confirms matching of blood donor and recipient and excludes the possibility of immediate haemolytic transfusion reactions. Delayed haemolytic transfusion reactions and febrile (non-haemolytic) reactions may still occur.
Uncrossmatched, or even incompatible, blood may be issued in life-threatening emergencies, even when alloantibodies are known to be present, if there is no compatible blood available. Consultation with haematologist is recommended.
