The HLA-B27 Flowcytometry Test is a blood test that detects the presence of the HLA-B27 antigen (a protein found on white blood cells) using flow cytometry, a laboratory technique that identifies and analyzes physical and chemical characteristics of cells.
Unlike PCR testing (which detects genetic material), flow cytometry identifies the HLA-B27 protein directly on the cell surface. This method is faster and widely used in clinical labs for initial screening.

    Description

    Why It’s Done:

    This test is commonly ordered to:
    • Aid in the diagnosis of autoimmune and inflammatory conditions, especially:
    o Ankylosing spondylitis
    o Reactive arthritis
    o Psoriatic arthritis
    o Juvenile idiopathic arthritis
    o Anterior uveitis
    • Investigate chronic lower back pain, joint stiffness, or unexplained inflammation, especially in young adults.
    • Support clinical suspicion of an HLA-B27–associated condition when symptoms are present.
    • Identify genetic predisposition in individuals with a family history of HLA-B27–related disorders.
    Note: A positive HLA-B27 result does not confirm a diagnosis but supports it in the presence of symptoms.

    Preparation:

    • No special preparation is needed.
    • Fasting is not required.
    • Inform your healthcare provider if you:
    o Are taking any medications.
    o Have symptoms such as joint pain, stiffness, or eye inflammation.
    o Have a family history of autoimmune disorders.
