Why do we perform histocompatibility testing?
The goal of histocompatibility testing is to ensure that a transplanted organ remains viable in the recipient for the longest period of time. Three sets of tests are performed to accomplish this goal. The first is determining the human leukocyte antigen (HLA) types of the patient and donor.
How do you check histocompatibility?
A histocompatibility antigen blood test looks at proteins called human leukocyte antigens (HLAs). These are found on the surface of almost all cells in the human body. HLAs are found in large amounts on the surface of white blood cells.
How does histocompatibility work?
The major histocompatibility complex (MHC) is a group of genes that encode proteins on the cell surface that have an important role in immune response. Their main role is in antigen presentation where MHC molecules display peptide fragments for recognition by appropriate T-cells.
What histocompatibility means?
Histocompatibility means that the nerve scaffold has no toxic side effects on nerve tissues, especially neither teratogenicity nor gene mutation, whereas nerve tissues, in turn, do not induce corrosive effects or immune rejection on the nerve scaffold.
What is Histocompatibility and Immunogenetics?
Histocompatibility and immunogenetics involves carrying out tests to support stem cell and organ transplantation. The work involves typing patients and donors, assessing the closeness of the match and thus helping to select the most appropriate donor for a particular patient.
What is HLA blood?
Human leukocyte antigens (HLA) are specialized proteins present on the surface of all cells in the body except red blood cells. The HLA genes that individuals inherit are responsible for the HLA antigens present on their cells.

How is HLA testing done?
How HLA testing is done. A sample of blood is taken by inserting a needle into a vein in your arm. Sometimes a swab of cells is taken from inside of your cheek (called a buccal swab) for testing. No special preparation is needed for either method.
What are the different types of histocompatibility?
There are two major types of MHC protein molecules—class I and class II. Class I MHC molecules span the membrane of almost every cell in an organism, while class II molecules are restricted to cells of the immune system called macrophages and lymphocytes.
