Manufacturer Narrative

The genomic dna sample was sent to grifols laboratory solution for sequencing.Sequencing interrogated jk exons 3-10 and the genotype jk*01n.18(588g), jk*02w.03 was identified with a predicted phenotype jka-, jkb+weak.The reported serology is jka-, in agreement with sequencing and discrepant with id core xt which reported jka+.The variant c.190c>t is described by isbt as the null allele jk*01n.18 associated with jka negative expression.Id core xt reported a predicted jka+ phenotype, but jk*01n.18(588g) null allele is associated with a predicted jka- phenotype.This false positive result obtained by id core xt is considered a discrepant result, and then a malfunction.This case report is associated with limitations of id core xt assay described in the id core xt package insert (limitations 1 and 10).
