- blood products undergo a meticulous collection, preparation and testing process to minimise the risks of blood transfusion
- donor selection
- testing of donor blood: groups (ABO, Rh), red cell antibodies and extended red cell antigen typing, infectious diseases, HLA typing, direct antiglobulin test
- processing into components and plasma derivatives
- viral testing
- sterile handling
- blood component labeling
- compatibility labeling
- irradiation if required (against donor lymphocytes)
- RBC: 2-6°C for up to 42 days (35 days for pediatrics)
- Platelets: 20-24°C for up to 5 days with continuous gentle agitation
- FFP/Cryo: <-25°C for 12 months
- meticulous attention to request form – request invalidated if any discrepancy
- group and hold/ type and screen: takes 45 min total
group or type
- ABO and Rh groups (forward and reverse typing tests) – takes 15 min
- antibody screen (for non-ABO Abs) – if found takes hours to resolve
- checking for duplicate records of patient and comparing historic results with new
- valid for 3 days if previous transfusion or pregnant in past 3 months
Cross match (total 1-2 hours)
- electronic cross match only if negative Ab screen (takes 1 hour total, including G&H)
- serological cross match of patients plasma with donor cells if positive Ab screen (takes 2 hours total)
- haemovigilance activities
- notification and investigation of an adverse transfusion reaction
- advice and information
