Thyroid ranges for teen

[Megaloo]

Does anyone know if thyroid ranges are the same for kids/under 18s as for adults?

I've got a GP appt in a couple of weeks to discuss 14 year old (with acute anxiety) results. I've only got the TSH result, and it's come back normal at 0.87 (levels 0.51-4.3).

Or am I safe to assume those would be the youngster levels they've used (if they are in fact different to adults)?
