Puzzler Case

Healthy athletic 17 yo female with no reported underlying disorders, medications, or unusual things for a CMP pre College with a slightly elevated Phosphate 4.6 (3.0-4.5 mg/dL) and alkaline phosphatase of 46 (52-144 u/L). By report all other lab values including calcium are normal. By report no dietary disorders. Could be biologic variation. The discord between the Phos and alkaline phosp are unusual (to me); Any thoughts especially why there would be discordant AP and Phos results?
