Molecular <scp>HPA</scp> genotyping by microarray in <scp>B</scp>razilian blood donors

Abstract

Allele frequencies were comparable to those described in other Brazilian studies. Rare HPA-9 alleles were described in Brazilians for the first time. A mutation near the HPA-2 polymorphism suggests that complementary methods might be necessary in specific cases. PLT genotyping by microarray proved to be fast, accurate, and reliable.
