The perfect match

ID HPA XT is a fast and effective solution for molecular typing of 12 HPA systems, designed and manufactured by Grifols*.

Recently, DNA-based testing has proved to be an extremely effective technique that can provide advantages over current serology techniques.

Within the BLOODchip® ID Line, Grifols offers ID HPA XT, an innovative human platelet antigen (HPA) genotyping assay that detects 13 polymorphisms determining 12 HPA systems. The kit is based on Luminex Technology, resulting in a highly reliable and accurate system.

BLOODchip® ID is the fastest and most effective solution for ensuring the safest transfusion therapy for your patients.


  • One multiplex PCR
  • No filtration required
  • Only 4 tubes to pipette


  • < 4h overall time from DNA to result
  • 30 min hands on time


  • From 1 to 96 samples per run
  • ID CORE XT and ID HPA XT can be performed in the same run

ID HPA XT main applications include, determining the presence/absence of platelet antigens in both patients and donors, performing large-scale donor typing for provision of antigen-negative platelets, helping to select compatible platelet donors for refractory or alloimmunized patients and complementing clinical history of alloimmune platelet disorders, such as foetal and neonatal alloimmune thrombocytopenia (FNAIT), post-transfusion purpura and platelet transfusion refractoriness. The final goal is to provide better matched units to improve patient care.
