I would not be concerned about that platelet count. Depending upon the lab reference values, the level is most likely just minimally elevated and would not cause anything to be concerned about. Absolute white cell numbers are difficult to assess without the context of your total white count. Frequently, a minor cold or other viral infection can lead to a short-lived rise in platelets and different types of white blood cells. I agree with having your lab work redone, but I would not worry about the current numbers.

These results suggest that your stomach issues might be due to an allergic reaction to food or a food intolerance. High eosinophils in the blood usually indicate an allergic type of reaction although more rarely it could be an autoimmune reaction or an infection. I cannot really speculate beyond that, but if you have been having stomach problems for so long, you might also benefit from seeing a gastroenterologist would could also look in your stomach to see if there is a high eosinophil count in the lining of your stomach or other areas of the digestive tract.
