Use of test
A specific variant of the human leukocyte antigen B51, HLA-B*51:08, is associated with Behcet's disease.
The presence of this variant adds weight to a clinical diagnosis of Behcet's disease.
This is a not a diagnostic test and the result does not prove or exclude a specific clinical diagnosis in an affected person.
This is an assay for heritable variants which can alter the probability that a person will develop a disorder. The test result is not, in isolation, diagnostic of a disease and the test result is not necessarily clinically significant for the patient's relatives.
Analysis of the gene sequence of the HLA-B genes for the presence of this specific variant.
Requesting the test
This test can be requested by any medical practitioner.
4 mL blood in EDTA. Specimens may be collected by the requesting practitioner or at any Sonic Healthcare collection centre (see link below).
To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.
We recommend that the patient or another adult check the labelling of request forms and sample tubes.
