What Is The Cause Of Bruising In A Child?

My grandson is 7 years old and has lots of energy, but he getting brused on his body. He was checked by his doctor, and had blood work done. His white and red blood cell are very low, and platelet count also very low. He was in the hospital for more blood work and bone marrow test, - Ruled out Lukiema and something about Aplastic Aniema. Doctors cannot figure out what is wrong. He feels fine, just the brusies he gets from jumping running and falling. I started giving he red meat which he rarely eats.
