Low Platelet Count - Abdominal Ultrasound

My sons platelets were low for several months and then the last test showed them in the normal range, low, but normal.  He also had an abdominal ultrasound to check his spleen since an abnormal spleen can cause low platelets.  His doctors were also a little concerned about all his bruises on his legs, but luckily they were just the result of being an active 3 year old and not a blood clotting problem.  When you hear the word platelet you just can't help but assume the worst - leukemia.  Luckily, the sleepless nights were short lived and he now seems to be doing much better.
