Is it common for bone age to be six months ahead?

Question

Hello doctor,

My son is 13 years old and is a little over 5' 2". Last year, we had a blood test which showed normal. But the bone age test showed his bones were six months to a year older than his actual age. I am 5' 10.5" and my wife is 5' 8". Should we check his growth hormone levels?

Answer 1

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

From what you have mentioned, according to the calculation of both parents, your son is expected to be taller likely 5’11.5”. Therefore his growth is above average. Besides, every child reaches puberty in their own time and experiences growth at their own pace. So there is nothing to worry about. This is normal. If he reaches beyond his maximal height after 21 years of age and has abnormal growth of his jaw or huge and broad foot, that could be a much greater concern in that sense.

Hope you get it now.
