Thank you for your query on Healthcare Magic.Alkaline phosphatase
is elevated in conditions involving bone and liver.
Bone problems like rickets and liver problems like hepatitis
, biliary obstruction will lead to elevation of this enzyme in the blood.
Other investigations to be done like serum calcium, phosphorous, and ultrasound
abdomen to be done to know the cause.
If you are scared of radiation
, you can opt for other nonradiation investigations like ultrasound or MRI after discussing with the doctor.
Hope I have answered your query.
