Part Description

LP29288-5   HLA
The human leukocyte antigen system (sometimes human lymphocyte antigen) (HLA) is the general name of a group of genes in the human major histocompatibility complex (MHC) region on human chromosome 6 (mouse chromosome 17) that encodes the cell-surface antigen -presenting proteins. The proteins encoded by HLAs are the proteins on the outer part of body cells that are (effectively) unique to that person. These proteins are sometimes designated the Mhc, although this convention is rarely observed. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Change Reason
This test is commonly performed on cells found in saliva and buccal swabs as well as blood specimens. Changed specimen from 'Bld' to 'Bld/Tiss' to represent both specimen types.Changed answer list from "Normative" to "Example" to fit the current LOINC model.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
Order vs. Observation
Both
