LOINC Code 53767-0: HLA-A+B+C SBT High resolution (Bld/Tiss) [Interp]

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component HLA-A+B+C SBT. 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+B+C SBT [Interpretation] by High resolution
• HLA-A+B+C SBT
• HLA-ABC sequence based typing results in HLA allele assignment for each HLA locus(A,B,C). HLA antigens are the major histocompatibility antigens. HLA Class 1 Sequence-Based typing (HLA-SBT) is used to identify HLA allelic polymorphisms at the level of individual nucleotides using genomic DNA amplified by polymerase chain reaction(PCR). If fewer than two alleles are reported for a locus, the patient can most likely be considered homozygous for that locus, but there is a possibility of an undetected rare allele. HLA-SBT should be used in addition to HLA Class 1 serology and/or low to intermediate resolution molecular typing using either SSP(sequence-specific primers) or SSOPH(sequence-specific oligonucleotide blot hydridization) technology. For clinical purposes, this test should be used as a reflex test to identify unrelated bone marrow donors who are HLA A,B, and C genotypic matches with the intended recipient.
