ID HPA XT is sold in the US and Canada for Research Use Only.
Not for use in diagnostic procedures

ID HPA XT is a fast and effective solution for molecular typing of 12 HPA systems, designed and manufactured by Grifols*. Based on Luminex xMAP® technology**, ID HPA XT is a qualitative genotyping assay for the simultaneous identification of multiple alleles encoding human platelet antigens (HPAs) in genomic DNA extracted from whole blood specimens collected in EDTA.

The test analyzes 13 polymorphisms to predict the presence of18 HPA phenotypes in 12 groups, including: HPA-1, HPA-2, HPA-3, HPA-4, HPA-5, HPA-6, HPA-7, HPA-8, HPA-9, HPA-10, HPA-11, and HPA-15. This test can be used to obtain in-depth knowledge of samples under study.

Molecular genotyping has been shown to be an extremely effective technique with many potential advantages over traditional serology.1

BLOODchip® ID is the fastest and most effective solution for human platelet antigen typing.
