A member asked:

Alk phos 159 in 16 year old... normal range 30-120. what would cause this to be raised? dr didn't seem concerned.

Normal for a teen: Assuming the 16 year old is still growing, that is a normal level. Alkaline phosphatase is higher when new bone growth is occurring.

This is normal: Reference range for a growing teen is five times an adult's. It from the growing bones. Stop worrying.
