The genomic dna sample was sent to grifols ih center for dna sequencing.Sequencing interrogated specific sequences: gypb gene exons 1-2; exons 4-6 and pseudo-exon 3 and the variant gypb:c.101c>t was identified.This variant is not currently described in the literature.Although its effect is unknown, the most probable location of this variant is on the allele gypb*s, based on the serology results, s -.Id core xt reported a predicted s+ phenotype, but the serology data from the user is s-, due to the variant gypb:c.101c>t.This false positive result obtained by id core xt is considered a discrepant result and then a malfunction.This limitation is covered by the general assay limitation described in the id core xt package insert (limitation 1 and 10).
