Alkaline Phosphatase (ALP)
ALP comes from several tissues, particularly the bile ducts and growing or remodelling bone. This blood test helps investigate either source.

Understanding the test
What does the Alkaline Phosphatase (ALP) test measure?
Also called Liver & Bone Enzyme
ALP may be requested to investigate bile flow or bone turnover. A change in liver enzymes, bone symptoms or a mineral imbalance can each suggest a different reason for measuring it.
When it may be requested
Bile flow
An ALP rise alongside other liver findings may prompt a closer look at the bile ducts.
Bone turnover
Bone-forming cells also contribute to ALP, which matters when patients are growing or bone disease is suspected.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
Intel Lab requests a fasting sample. Arrange a morning collection after the instructed overnight fast. A recent fatty meal can affect the intestinal contribution to ALP.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
ALP can rise during growth and pregnancy as well as in disease. The clinician uses the relevant reference interval and may compare GGT, calcium and phosphate.
What can affect it
- Total ALP does not identify its tissue of origin.

Open your laboratory report
Look for Alkaline Phosphatase (ALP) in your report. Use the sample type and collection time when comparing it with an earlier report.

Discuss the next step
Ask whether the accompanying GGT and mineral measurements suggest the source of the change is more likely liver or bone.

Patient questions
Before you book
How does my clinician distinguish a liver result from a bone result?
The pattern matters. GGT and other liver tests can support a liver or bile duct source. Age, pregnancy and bone-related measurements can change how the same ALP result is interpreted.
What is the difference between ALP and ALT?
They point to different kinds of liver problem. ALP comes mainly from the bile ducts and from bone, so a raised level suggests obstructed bile flow or bone activity. ALT comes from the liver cells themselves and rises when those cells are injured, for example in fatty liver or hepatitis. Reading the two together helps your doctor tell a bile duct pattern from a liver cell pattern.
Why is ALP higher in teenagers?
Growing bones release ALP, so a healthy teenager can have a result above the adult range. Compare it with the range for their age. If it exceeds that range or stays raised, the clinician can use the other liver and bone findings to decide what to check next.
