The neurologists' secretary called today to ask me if my 7 year old daughter had a cold a few weeks back when she had her blood tests done. I told her I didn't recall her having had any cold at all. I asked her why and she told me that my daughters' white blood count was low. I told her the only difference between this blood test and the last one is that my daughter now takes Ritalin (she's ADHD).
This is what I don't understand: she told me the normal numbers are supposed to be between 4.5 - 13 (something like that) and that my daughters' was 3.8.
Can anyone explain this to me, is there something else wrong with her? Now I'm really worried about her

. I don't know a lot about epilepcy, my daughter had only 1 seizure (it happened at school), we took her to emergency at the childrens hospital. They did an EEG (abnormal brain wave activity) and a CT scan of her brain (normal). They put her on Tegretol.
She has not had any other seizures, unless she has the staring kind that i haven't noticed. She did kind of daydream but that's been better since the Ritalin.
Her appointment with the neurologist is on March 17th and they want her to redo the blood test to check the numbers again and we'll get the results of her recent EEG (about 3 weeks ago).
Anyone with info or suggestions about the number stuff please respond.
