HLA B-27

Human leukocyte antigens (HLAs) are proteins commonly found on white blood cells. These antigens help your immune system identify the differences between healthy body tissue and foreign substances that may cause infection.

Although most HLAs protect your body from harm, HLA-B27 is a specific type of protein that contributes to immune system dysfunction. The presence of HLA-B27 on your white blood cells can cause your immune system to attack those otherwise healthy cells. When this occurs, it can result in autoimmune disease or immune-mediated diseases, such as juvenile rheumatoid arthritis or ankylosing spondylitis.

Symptoms HLA B27 Syndrome

For people with specific symptoms, the HLA-B27 test may be used along with other blood, urine, or imaging tests to confirm the diagnosis of an autoimmune disease. The symptoms that might prompt a doctor to order the test include:

  • Joint pain
  • Stiffness or swelling of your spine, neck, or chest
  • Inflammation of your joints or urethra accompanied by skin lesions
  • Recurring inflammation in your eye

The doctor can advise HLA antigen tests, including tests for HLA-B27, when you’re undergoing a kidney or bone marrow transplant. These tests can be used to ensure a suitable match between you and a donor.

HLA B-27 Test Result

A negative test indicates the absence of HLA-B27 in your blood.

However, if the test is negative, it doesn’t mean that you don’t have an autoimmune disorder. When making a final diagnosis, your doctor will consider all test results along with your symptoms. Sometimes people with autoimmune disorders don’t have HLA-B27 on their white blood cells.

If the test is positive, this means that HLA-B27 is present in your blood. Although a positive result may be cause for concern, the presence of the antigen doesn’t always mean that an autoimmune disorder will develop. Diagnosis of an autoimmune disorder must be made based on your symptoms and the results of all blood tests and diagnostic exams.

What is HLA-B27 antigen?

HLA-B27 (Human leukocyte antigen-B27) is a type of antigen present on the surface of cells and it is the specific antigen responsible for the manifestation of the ankylosing spondylitis. Ankylosing spondylitis develops due to the presence of genes associated with the formation of HLA-B27 antigens on the cell surfaces. The presence of this antigen on the cell surface of leukocytes in an individual causes the immune system to attack its own healthy tissue/organs like tissues of the bones and the joints.

Conclusion

The HLA-B27 blood test is one step in the process of diagnosing a potential autoimmune disorder. Neither positive nor negative results to the test should be taken as confirmation of whether you have an autoimmune disorder or not. Your doctor will talk to you about the next steps after you receive the results.
