I wouldn't suggest this at all. Gastric ulcers at age 3 are exceptionally rare, especially H pylori infections (they have significantly decreased in the industrialized world for the past 50 years). The fact that she doesn't have anemia highly suggests against an active bleeding process, especially if it was brisk enough to have a platelet count of 8,000. If this was a bleeding process, she would definitely be anemic and iron deficient at this point. The hematologist would have also noticed a reticulocytosis on the blood smear if there was active bleeding and she was producing enough retics to not be anemic (and even if she was, her MCV would be significantly high, which it isn't). ITP is far more common at this age, her presentation, symptoms, and results are highly supportive of this at this point.
