ICD-Code T86.00: Bone-marrow transplant rejection

You are not producing enough blood cells after you were given blood stem cells from another person in the past.

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. The red blood cells carry oxygen from the lungs throughout the body. White blood cells are part of the body’s immune system. They fight pathogens. Platelets are important for blood clotting. Stem cells are cells that can develop into different types of cells. Blood cells develop from the blood stem cells. In adults, blood stem cells are mainly found inside some bones. From there, the mature blood cells are released into the blood. A small amount of blood stem cells also enters the blood.

You were given blood stem cells from another person. These blood stem cells are supposed to form blood cells. However, the blood stem cells do not work properly in your case. Because of this, you have too few blood cells.

If you have too few blood cells in your body you may have different problems. For example, if you have too few red blood cells, you may be pale and weak. If you have too few white blood cells, then you are more susceptible to illnesses. If you have too few platelets, you can bleed more quickly, for example.
