Hi. My daughter is 7 months old. She has been getting eye infections. First she had a cold which was resolved but eye infection s still coming back. We took her for blood tests to check for allergies and got the results back yesterday.Her blood count came back normal. Allergy count is 28, they checked for all the come allergies, wheat, cats, dogs, yolk etc. and everything came back normal. Doctor said she definitely has an allergy and that I should give her Singulair and an anti-histamine for 2 weeks and then he wants to see her. I don’t understand why we cannot pick up what the problem is, don’t blood tests show everything?
