Thanks so much, Whizbang. Yes--the hepatitis has been treated and was thought to be autoimmune hepatitis. Hepatitis associated aplastic anemia is rare. His lowest platelet count has been 6 and he's receiving platelet transfusions every 5-6 days while we wait to find a donor. He is not producing many white "baby cells." Our other son is being tested now but I know better than to hang my hopes on a 25% chance. Thank you for the encouraging word about your company. The best we were hoping for is for them to continue his insurance for 3 months; this gives me hope that it could be longer. Our son has applied for disability. Every encouraging word helps so much!
