I got the results of a blood test my son had done yesterday (he was truly so sweet and so brave while it was being done - remained stock still with his arm out, crying gently and pitifully). His hyperactivity is not due to thyroid problems - this is normal. However he has a very low neutrophile count and high eosonophile count (both out of normal range). Also low hematocrit level. This means absolutely nothing to me. I will see the doctor next week to have it all explained but wondered in the meantime if any scientific bods had any insight into this...?
