HLA B27 Test Normal Range
The HLA B27 test is a blood test that looks for the presence of a protein called HLA-B27 on the surface of white blood cells. HLA-B27 is a human leukocyte antigen (HLA), which is a protein that helps the body’s immune system distinguish between its own cells and foreign invaders.
A positive HLA B27 test result means that the person has the HLA-B27 protein on their white blood cells. This does not necessarily mean that they have a disease, but it does mean that they are at an increased risk of developing certain autoimmune disorders, such as
* Ankylosing spondylitis
* Reactive arthritis
* Psoriatic arthritis
* Inflammatory bowel disease
The normal range for the HLA B27 test is negative. This means that the person does not have the HLA-B27 protein on their white blood cells. However, it is important to note that a negative test result does not rule out the possibility of having an autoimmune disorder. There are other factors that can contribute to the development of these disorders, such as genetics, environment, and lifestyle.
The HLA B27 test is typically ordered by a doctor if a person is experiencing symptoms of an autoimmune disorder, such as joint pain, stiffness, or swelling. The test may also be ordered if a person is planning to have an organ transplant. This is because HLA compatibility is important for a successful transplant.
If you have a positive HLA B27 test result, it is important to talk to your doctor about your risk of developing an autoimmune disorder. They can monitor you for symptoms and recommend treatment if necessary.
Here are some additional things to keep in mind about the HLA B27 test
* The test is not always accurate. A small percentage of people with autoimmune disorders will have a negative HLA B27 test result, and a small percentage of people with a positive HLA B27 test result will not develop an autoimmune disorder.
* The test is not necessary for everyone. If you are not experiencing symptoms of an autoimmune disorder, there is no need to have the test.
* The test is not a substitute for a diagnosis. If you have a positive HLA B27 test result, it is important to see a doctor to rule out any underlying medical conditions.
