Histocompatibility antigen test
What is Histocompatibility Antigen Test?
A Histocompatibility antigen test is a type of medical test which is used to determine if two individuals are related, or if one has strong enough tissue to be used in a transplant. The test looks for antigens (or proteins) on the surface of white blood cells, called human leukocyte antigens (HLA).
Preparation for a Histocompatibility Antigen Test
A Histocompatibility antigen test does not require any special preparation. However, the patient may be asked to provide a sample of blood for the test. This sample can be drawn in the clinic or in a laboratory.
Procedure for a Histocompatibility Antigen Test
During a Histocompatibility antigen test, the patient’s blood sample is incubated with labeled antibodies. These antibodies bind to antigens on the surface of the blood cells. The sample is then analyzed for the presence or absence of the HLA antigens using advanced flow cytometry technology.
Types of Histocompatibility Antigen Test
- Typing: This is the most common type of Histocompatibility antigen test and it is used to test for the presence or absence of certain HLAs.
- Matching: This is a more in-depth type of Histocompatibility antigen testing that can provide detailed information about the person’s HLA type.
Risks of a Histocompatibility Antigen Test
The risks associated with a Histocompatibility antigen test are minimal. There is a slight risk of infection or bleeding due to the needle prick when obtaining the sample, but these risks are minimal.
Why is a Histocompatibility Antigen Test Important?
The Histocompatibility antigen test is important because it can identify if two individuals are related or if a tissue transplant is likely to be successful. It is also important for determining if someone has a higher risk of developing certain autoimmune diseases.
When to Have a Histocompatibility Antigen Test?
Histocompatibility antigen testing is used when two individuals are being considered for a possible tissue transplant. It may also be done if an individual has an autoimmune disease in order to determine if he or she may be at higher risk of developing other autoimmune diseases. The test can also be used to determine if two individuals are related or if a person is a tissue match for another individual.
