Why Is the ALP Isoenzyme Test Done?
Doctors recommend this test when total ALP levels are elevated and the source is unclear.
Common clinical indications include:
- Persistently elevated ALP
- Suspected liver or bile duct disease
- Bone pain or suspected bone disorders
- Metabolic bone disease
- Paediatric evaluation of abnormal ALP
- Monitoring known liver or bone conditions
Clinical value:
- Differentiates liver-related ALP from bone-related ALP
- Helps avoid unnecessary investigations
- Supports accurate diagnosis and follow-up
