What are possible complications of the human leukocyte antigen test?
Risks for this test are minimal, but may include slight bleeding from the blood-drawing site, fainting or feeling lightheaded after venipuncture, or hematoma (blood accumulating under the puncture site).
Under what circumstances is the human leukocyte antigen test conducted?
Testing is done to diminish the likelihood of rejection after transplant, and to avoid graft-versus-host disease (GVHD) following major organ or bone marrow transplantation.
What role does the human leukocyte antigen test play in pathology?
Certain HLA types have been linked to diseases, such as rheumatoid arthritis, multiple sclerosis, serum lupus erythematosus, and other autoimmune disorders.
How can one test for bone marrow donor eligibility?
To test for bone marrow donor eligibility, individuals can undergo a simple blood test to determine their human leukocyte antigen (HLA) type. This test helps match donors with recipients to increase the likelihood of a successful transplant. Additionally, potential donors will also undergo a physical exam and medical history review to ensure they are in good health and able to donate.
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.
Why do you test for leukocyte esterase?
Leukocyte esterase is a test used to help determine whether a person has a urinary tract infection.
What color tube leukocyte count blood test?
blue tube
What causes leukocyte esterase in urine?
A cause of leukocyte esterase in urine is an urinary tract infection. Leukocyte esterase is a test used to detect a specific substance that indicates that there may be white blood cells in urine.
A screening test to detect prostate cancer that measures protein levels is called?
The prostate-specific antigen (PSA) test is a blood screen for prostate cancer.
Is pregnancy test an antigen-antibody 'agglutination' or 'preciptation' reaction?
Its an agglutination test
Which item is from the patient in a direct ELISA test?
antigen
What is a precipitin test used for?
A precipitin test is used to determine if someone has been exposed to a specific antigen by detecting the presence of antibodies in their blood. This test is commonly used to diagnose certain infections or to confirm exposure to allergens.
