LOINC Code 96617-6: HLA-A unresolved alleles High resolution Nom (Bld/Tiss)

96617-6 is a LOINC code used to identify HLA-A unresolved alleles High resolution Nom (Bld/Tiss) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component HLA-A unresolved alleles. It is commonly used with the system or sample type Bld/Tiss.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation
  • Method: High resolution

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

HLA-A unresolved alleles [Type] by High resolution
HLA-A unresolved alleles
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 [PMID22001389]. 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.
