96675-4

LOINC code 96675-4 identifies "HLA-DRB3 and HLA-DRB4 and HLA DRB5 unresolved alleles [Type] by High resolution". HLA unresolved alleles are alleles that have ambiguous typing assignments; it's a way of listing which allele assignments are uncertain relevant to the level of resolution. It has been recommended that reports include all uncertainty in the HLA typing assignment relevant to the level of resolution as stated. As such, this term is intended to report the genotypes and/or alleles that have not been excluded and therefore, should be listed in the report [PMID:22001389]. Due to the variability in reporting and updates, example answer lists are not provided, however, the following resource can provide examples of expected answers- https://www.ebi.ac.uk/ipd/imgt/hla/ambig.html.

This code measures HLA-DRB3 & HLA-DRB4 & HLA DRB5 unresolved alleles in Bld/Tiss. It belongs to the HLA class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
