This is a blood test to detect the presence of HLA-B27 in white blood cells.
The test is conducted to look for specific protein found on the surface of white blood cells. The protein is called human leukocyte antigen B27 (HLA-B27) that help the body's immune system tell the difference between its own cells and foreign, harmful substances.
The test is referred when you have symptoms of chronic inflammation, pain, and stiffness in certain areas of your body, such as your back, neck, and chest, or eyes, especially if you are male. A positive test means HLA-B27 is present. It suggests a greater-than-average risk for developing Ankylosing spondylitis, Reiter syndrome or Sacroiliitis (inflammation of the sacroiliac joint).
If HLA-B27 is not present, then the association is not there.

The HLA â?? B27 test costs about 30 US dollars. This test helps in diagnosing suspected diseases like reactive arthritis.

HLA B27 is a specific protein found on the surface of cells that plays a crucial role in the immune system. It is part of the human leukocyte antigen (HLA) system, which helps the body recognize foreign substances. The presence of HLA B27 is associated with certain autoimmune conditions, particularly ankylosing spondylitis and other spondyloarthritis. Individuals with this antigen may have an increased risk of developing these disorders, although not everyone with HLA B27 will experience them.

The HLA test requires a blood sample. There is no need for the patient to fast before the test
The utility of HLA-B27 teating depends on the pretest probability of disease.
The human leukocyte antigen test, also known as HLA, is a test that detects antigens (genetic markers) on white blood cells. There are four types of human leukocyte antigens: HLA-A, HLA-B, HLA-C, and HLA-D.
The results for HLA B27 testing typically take about 1 to 2 weeks to return. This can vary depending on the laboratory's processing time and the specific testing methods used. In some cases, results may be available sooner, particularly if the test is conducted in-house at a medical facility. Always consult with your healthcare provider for the most accurate time frame based on your specific situation.
