Показать описание
HLA test is Human Leukocyte Antigen test, also known as Tissue typing or Histocompatibility testing.

They are specialized proteins present on the surface of all cells in the body. The HLA genes that people inherit are the reason for the HLA antigens present on their cells.

A pattern of antigens, called a tissue type, is inherited from your parents. Half comes from your mother and half comes from your father. Everyone has their own pattern except for identical twins, who have the same pattern and are an identical match for tissue and blood cells.

Brothers and sisters who have the same parents have a 1 in 4 chance of being an identical match.
