High Alkaline Phosphotase (6,000) in one year old

My daughter is almost 13 months old. She has not grown in the past 3 months so our PCP decided to do a blood test. The results of the test revealed a high Alkaline Phosphotase level of 5400 -- the test was rerun and the result was 6,000. More detailed blood work revealed that the APs were coming from the bone, but xrays and all other blood work were normal, Our daughter is otherwise health and very busy -- she was an early walker around 10 months and always on the go. We are told that we should monitor this condition with our PCP but we are wondering if there are other tests/steps we should be taking.
Thank you for your help.

I am not a pediatrician - however, if this were an adult, bone diseases like myeloma can be considered.  One consideration regardness would be a bone scan, which could be a reasonable initial evaluation for bony disease.  

Another consideration would be a benign condition known as transient hyperphosphatasemia of infancy.  It can follow a viral illness, and can be discussed with your personal physician.  More information can be found here:

Followup with your personal physician is essential.
