Manufacturer Narrative

Sequencing interpretation: an allele combination that is atypical (homozygous bb at 1006 while 733 is heterozygous) triggered a "pv" on v which is necessary to determine if a variant c is present [c (+)*].This was the source of the discrepancy, since some serological reagents will detect this as c-positive, however it is not the canonical rhc antigen.1,2.The rhd testing supports this and that a variant c [c(+)*] is present.The atypical allele combination on hea precluded the test's ability make the c(+)* call definitively since the variant c occurs in trans with another rhce variant which caused the pv on v.Results from both the hea and rhd beadchip also predict a v- status.

Event Description

The customer reported a possible discrepancy.The donor is c- using the bioarray hea molecular beadchip kit; serology results were c+.
