What is the blood tissue antigen that is present in 90 percent if individuals who have AS?
HLA-B27
What does a HLA-B27 blood test detect?
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.

HLA-B27 antigen?
DefinitionHLA-B27 is a blood test to look for specific protein found on the surface of white blood cells. The protein is called human leukocyte antigen B27 (HLA-B27).Human leukocyte antigens (HLAs) are proteins that help the body's immune system tell the difference between its own cells and foreign, harmful substances.See also: Histocompatibility antigen testAlternative NamesHuman leukocyte antigen B27How the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic. An elastic band is placed around the upper arm to apply pressure and cause the vein to swell with blood.A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children:The area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. A bandage may be applied to the puncture site if there is any bleeding.How to prepare for the testNo special preparation is usually necessary.How the test will feelWhen the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedYour doctor may order this test if you have joint pain, stiffness, or swelling. HLA type B27 is associated with autoimmune diseases such as ankylosing spondylitis and Reiter syndrome. The test may be done along with other tests, including an ESR, C-reactive protein, and rheumatoid factor.HLA antigen testing is also used to match donated tissue to organ recipients. For example, it may be done when a person needs a kidney transplantor bone marrow transplant.Normal ValuesA normal (negative) result means HLA-B27 is absent.However, HLA-B27 is found in 5 - 7% of Caucasians who do not have an autoimmune disorder.What abnormal results meanA positive test means HLA-B27 is present. It suggests a greater-than-average risk for developing:Ankylosing spondylitisReiter syndromeSacroiliitis (inflammation of the sacroiliac joint)In the presence of suggestive clinical findings, a positive HLA-B27 test may confirm the diagnosis.What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)
What is the importance of HLA?
Human leukocyte antigen (HLA) matching is done when doctors are trying to find bone marrow or cord blood matches for a patient that needs one or both of these things. HLA matching is not as simple as knowing a person needs cord blood or bone marrow and finding someone who is willing to donate, it's a very delicate process to ensure that there will not be any ill effects from the transplantation of either material into the patient in need. HLA antigens are found on most cells in your body and your system uses these proteins or markers to recognize which cells belong in your body and which do not. If your donors HLA antigens are different from yours, your body will respond accordingly and attack those cells. A close HLA match needs to be found to decrease the chance that your immune cells will attack your donor's cells or that your donor's immune cells will attack your body after the transplant.
What preparation is required prior to HLA testing?
The HLA test requires a blood sample. There is no need for the patient to fast before the test
