Description
The Human Leukocyte Antigen (HLA) test, also known as HLA typing or tissue typing, is a specialized blood test used to identify specific proteins present on the surface of cells. These proteins play a critical role in how the immune system recognizes self versus foreign tissue.
HLA markers are especially important in organ and bone marrow transplantation, autoimmune disease evaluation, and immune system compatibility testing.
What Is an HLA Test?
The HLA test analyzes genes that control the production of HLA proteins. These proteins help the immune system decide whether cells belong to the body or should be attacked. A close match between donor and recipient HLA types reduces the risk of transplant rejection.
Why Is HLA Typing Performed?
This test is commonly used to:
- Match organ or bone marrow donors and recipients
- Diagnose autoimmune diseases
- Evaluate immune system disorders
- Assess genetic susceptibility to certain diseases
- Support transplant planning
How Is the HLA Test Done?
A small blood sample is collected from a vein and sent to a laboratory for genetic and immunological analysis. In some cases, cheek swab samples may also be used.
The procedure is simple and causes minimal discomfort.
Why HLA Testing Is Important
- Improves transplant success rates
- Reduces risk of tissue rejection
- Helps identify immune-related conditions
- Supports accurate medical decisions
Book an HLA Test
If you are preparing for an organ transplant, bone marrow transplant, or immune-related evaluation, an HLA test provides essential information to ensure compatibility and better treatment outcomes.
