I also got a low number. Is this what you came up with?

mg/m2/day =  mg/day divided by surface area

so,

If mg/day =  5mg and m2 = .976, then the mg/m2/day would be 5 divided by .976,  which = 5.12 mg/m2/day.

If mg/dya = 7.5mg and m2 = .976, then the mg/m2/dya would be 7.5 divided by .976, which = 7.68 mg/m2/day.

Jack is doing well (or well?). Thanks for asking. I still think he is on a very low dose, 7.86mg/m2/day. He seems to be growing at a normal rate, has lost much of his huge appetite, and hasn't been ill. The one big thing I have noticed is an increase in emotional instability. Hard to tell if he is leaning undersupressed now, or if he is just a typical 2 1/2 year old. He is due for a blood draw. We are set to go in tomorrow morning. Although, I just called the lab and the person who does his draws left early today. The receptionist wasn't sure if she was ill. Since Jack is so difficult to get a draw from, I will call in the morning before we leave. If she isn't there,  I guess we will have to wait a day. We will find out his levels in about 2 weeks. I definitly will post then. Everyone here is so wonderfully supportive. I don't think I could get through this without this board. Thanks again for asking. HOpe all is well with you guys.
