Read complete answer here. Beside this, what does it mean to test positive for HLA?
A positive result means HLA-B27 was found in your blood. You may have a higher-than-average risk of certain autoimmune diseases, such as ankylosing spondylitis and reactive arthritis. If you are white, you are more likely to test positive for the HLA-B27 antigens.
Beside above, what is HLA testing used for? Human leukocyte antigen (HLA) typing is used to match patients and donors for bone marrow or cord blood transplants. HLA are proteins -- or markers -- found on most cells in your body. Your immune system uses these markers to recognize which cells belong in your body and which do not.
Subsequently, one may also ask, what is HLA in your blood?
HLA-B27 is a blood test to look for a protein that is 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.
How is an HLA test done?
A: HLA testing is performed on a sample of blood. An individual's HLA typing can be determined by testing the HLA proteins on the surface of white blood cells or by testing DNA from the same cells. A: HLA typing is performed in laboratories by trained technologists using blood drawn from a person's arm.
