Part Descriptions

LP157778-4   HNA 2
The HNA 2 system has one allele - HNA-2a, which is expressed only on subpopulations of neutrophils and neutrophil precursors (CD177). The expression of HNA-2a is greater in women than men. It is also greater in pregnant women than in healthy female donors. Source: Regenstrief LOINC

LP157779-2   HNA 2 Ab
Neutrophil-associated antibodies may cause neutropenia in various autoimmune disorders including Felty's syndrome, SLE and drug-induced neutropenia. Febrile transfusion reactions and isoimmune neonatal neutropenia may also be caused by antibodies to neutrophil-specific antigens or HLA antigens. Source: ARUP Laboratories

Change Reason
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.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
