HI there. My 6 year old got high blood tests back and he has a high IgA. 2.03 Low MCV 73.9. and High Platelet count of 554. Microcytosis +1. Over the past 3 weeks he has experienced a cold/flu symptoms, Norwalk symptoms, Extremely high fever, about 24 heavy nosebleeds which are hard to settle down, a bad ear infection. Sore in the legs, easily bruising. Nightmares. Now extremely attentive and affectionate, and his speech seems to have gone backwards. Can you give any advice? I have taken him to the doctor, gotten a medication for the ear infection and the blood test done. Those are the results. the doc is now suggesting to do allergy testing....is there anything else you can suggest I ask for? Thanks for the advice.
