The Alkaline Phosphatase (ALP) Isoenzyme test is a specialised blood test used to identify the source of elevated ALP levels, most commonly liver or bone disorders.
In Indian clinical practice, elevated ALP is frequently encountered during routine testing.

The isoenzyme test helps clinicians determine whether the elevation is due to hepatic, biliary, or skeletal causes, enabling more targeted evaluation and management.

At Torrent Diagnostics, ALP isoenzyme analysis is performed using validated laboratory separation techniques, ensuring clinically meaningful differentiation.

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

Who Should Get the Test?

You may be advised this test if:

  • Routine blood tests show high ALP
  • You have symptoms of liver disease (jaundice, itching)
  • You have bone pain, fractures, or deformities
  • Imaging suggests liver or bone pathology

Common use in India:

  • Cholestatic liver disease
  • Vitamin D deficiency-related bone disease
  • Evaluation of persistently high ALP in children
  • Paget’s disease of bone

FAQs To Help You Know Better

Is fasting required?
No, fasting is not required.
Is this test done routinely?
No, it is done when total ALP levels are elevated.
Can Vitamin D deficiency raise ALP?
Yes, it can increase the levels of ALP indicating an underlying bone disease.
Is high ALP always abnormal?
No. Children and adolescents may have physiologically high levels.
Can this test detect cancer?
No. It helps identify the source of enzyme elevation.
