Molecular Typing (SSOP)
The presence of HLA-B27 may help to confirm the diagnosis and aid in treatment of Ankylosing Spondylitis. There is a strong association with the HLA class I molecule HLA-B27, found in 90% of patients with Ankylosing Spondylitis. This association is one of the strongest genetic associations with a common disease, although the mechanism of action remains undefined.
Interpretive report will indicate presence or absence of HLA-B27.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Ankylosing Spondylitis cannot be diagnosed or ruled out by this test.
