I am confused, I have been told by many nurses that I have "thin blood." I understand that thin blood makes it harder to form clots. I bruise really easily and have unexplained bruising up and down my arms and legs. I have had previous blood tests that show I am severely anemic. Also tests which show that I have both low red blood cell count and low platelet count. I am not sure what this means? I know I'm anemic and my iron is low, but I don't know what the low counts mean? Does one of them cause the "thin blood?"
