You have had an examination to find out how active certain genes are in specific white blood cells.

Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. White blood cells are part of the body’s immune system. They fight pathogens.

Somatic cells and therefore also the white blood cells usually hold a complete blueprint of your body. This blueprint consists of genetic information. Individual sections of genetic information are called genes. Genes contain instructions according to which a cell produces certain proteins. These proteins control many processes in the cell, for example, immune function. A gene can be active to varying degrees. The activity of a gene determines how much of a particular protein the cell produces. This investigation involved taking your blood and then examining it in a laboratory using special methods.
