Our lab carries out human platelet antigen (HPA) and human neutrophil antigen (HNA) genotyping and antibody screening.
Fetal/neonatal alloimmune thrombocytopenia (FNAIT)
HPA antibody and genotype testing is used in suspected cases of FNAIT.
Our form for initial request of FNAIT investigation should be completed with SNBTS clinical staff.
Post-transfusion purpura (PTP)
HPA antibody and genotype testing is used in suspected cases of PTP.
Transfusion-related acute lung injury (TRALI)
Human leucocyte antigen (HLA) and human neutrophil antigen (HNA) antibody screening are used in suspected cases of TRALI.
Our form for TRALI investigation should be completed with SNBTS clinical staff.
You should note that all samples for HNA testing and confirmatory HPA antibody testing by monoclonal antibody-specific immobilization of platelet antigen (MAIPA) will be sent to the NHS Blood and Transplant (NHSBT) Platelet and Granulocyte Reference Lab in Filton, Bristol.
All samples must be sent with the relevant request form and must be less than 48 hours old when received by the lab.
