Frequently Asked Questions
What is HLA-B27 test used for?
The HLA-B27 DNA test detects the presence of the HLA-B27 gene, which is strongly associated with ankylosing spondylitis and other seronegative spondyloarthropathies.
Is fasting required for HLA-B27 test?
No, fasting is not required. This is a genetic test performed on whole blood EDTA sample.
How long does it take to get results?
Reports are typically available within 3 to 5 working days from sample receipt at Dr. Patho Labs.
What does a positive HLA-B27 result mean?
A positive result indicates the presence of the HLA-B27 gene. However, it does not confirm disease on its own, as some healthy individuals carry this gene. Clinical correlation with symptoms like chronic back pain, stiffness, and inflammation is essential.
Can HLA-B27 test diagnose ankylosing spondylitis?
No, it is not a standalone diagnostic test. It supports diagnosis when combined with clinical features, imaging findings, and inflammatory markers like ESR and CRP.
Who should get an HLA-B27 test?
It is recommended for patients with chronic inflammatory back pain lasting more than 3 months, early-onset arthritis, family history of spondyloarthropathy, or unexplained uveitis and psoriasis.
