Thanks for the reply. I don't know what tests she has had other than some sort of blood work that was drawn on an outpatient basis. It was so long ago now that I can't remember. Seems to me one of them was testosterone. Anyway, I will ask about the things you mentioned on her visit in two weeks. Could you explain what the relevence of bone age is? I can tell you that she is growing in height very well, 3-1/2 inches in the last year, and is at the 50% percentile for a 4-year-old child. Her weight, however, is not keeping up and she is not even on the chart for weight. Her extreme prematurity at birth may be a factor in this, however.
