How to prepare
No specific preparation is required for an amylase blood test. However, if you are experiencing acute abdominal pain, please contact your GP or present to an emergency department rather than waiting for a routine blood collection. Inform the pathology centre of any symptoms you are currently experiencing.
After the test
Share your results with your GP. If your amylase is significantly elevated, your practitioner will likely want to assess you in person and may refer you for imaging (ultrasound or CT). Do not wait for results if you are experiencing severe, acute abdominal pain — seek urgent medical attention.
Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.
Understanding results
Amylase is measured in units per litre (U/L). Reference ranges vary slightly between laboratories, but most adult reference ranges fall between 25 and 125 U/L.
- Elevated amylase: Most commonly seen in acute pancreatitis, where levels may be 3–10 times the upper limit of normal. Also elevated in salivary gland conditions, bowel obstruction, and kidney disease.
- Normal amylase: Does not rule out pancreatitis, particularly if blood is drawn late in the course of illness (amylase returns to normal within 3–5 days) or in chronic pancreatitis where enzyme production may be reduced.
- Low amylase: Seen in advanced chronic pancreatitis where the gland has lost significant function.
Amylase results should always be interpreted alongside lipase, clinical symptoms, and imaging when pancreatitis is suspected.
