Active

Part Description

LP16560-2 HLA-B27
HLA-B27 is an allele of the human HLA-B locus that is present in 1% of Asians, 3-4% of African-Americans, and 6-8% of Caucasians. HLA-B27 bears a strong association with ankylosing spondylitits (Marie-Strumpell disease), more than 90% of patients express this antigen. An HLA-B27 positive individual with consistent clinical and radiographic findings has an 100 fold greater risk of developing ankylosing spondylitis than a negative individual. The antigen is less strongly associated with Reiter's syndrome, psoriatic arthritis and juvenile rheumatoid arthritis. It has also been linked with congenital deficiency of complement components C2 and C4, adrenal hyperplasia, and inflammatory bowel disease. Copyright Copyright © 2006 - 2008 ClinLab Navigator, LLC.

Basic Attributes

Class: HLA
Type: Laboratory
First Released: Version 2.00
Last Updated: Version 2.73 (MIN)
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.; 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
