The Amylase Blood Test measures amylase, a digestive enzyme primarily produced by the pancreas and salivary glands. It is commonly used to investigate pancreatic disorders, abdominal pain, and digestive symptoms. Testing is performed in a UKAS-accredited laboratory, with fast results and an optional GP consultation.
What is an Amylase Blood Test?
Amylase is an enzyme responsible for breaking down carbohydrates into sugars during digestion. It is produced mainly by the pancreas, with smaller amounts released by the salivary glands.
When the pancreas becomes inflamed or damaged, amylase can leak into the bloodstream, causing elevated levels. The amylase test is therefore widely used in the investigation of acute pancreatitis, pancreatic injury, and other abdominal conditions.
The test may also help assess:
- Pancreatic inflammation or blockage
- Salivary gland disorders
- Gastrointestinal causes of abdominal pain
At London Blood Tests, amylase is measured using validated enzymatic methods in line with UK clinical standards.
Benefits of the Amylase Test
- Key Marker of Pancreatic Health
Helps detect inflammation or injury of the pancreas.
- Supports Diagnosis of Acute Pancreatitis
Often rises rapidly during pancreatic inflammation.
- Assists Investigation of Abdominal Pain
Useful when symptoms involve the upper abdomen.
- Quick & Non-Invasive
Requires only a simple blood sample.
- Useful in Emergency & Routine Testing
Applied in both urgent and outpatient settings.
- Cost-Effective Digestive Health Test
Affordable marker for pancreatic assessment.
- Optional GP Consultation for Interpretation
Results reviewed with a GP if abnormal.
Why Do I Need an Amylase Blood Test?
You may benefit from an amylase test if you experience:
- Severe or persistent upper abdominal pain
- Pain radiating to the back
- Nausea or vomiting
- Fever with abdominal discomfort
- Unexplained digestive symptoms
Testing is commonly recommended if:
- Pancreatitis is suspected
- There is a history of gallstones or heavy alcohol use
- Pancreatic or salivary gland disease is being investigated
- Abnormal imaging or other digestive tests are present
Because pancreatic conditions can progress rapidly, early testing supports prompt diagnosis and management.

Your Amylase Test Results – Explained
Amylase levels are reported in U/L.
Typical UK reference range:
- 30–110 U/L (may vary slightly by laboratory)
Interpretation:
- High amylase: acute pancreatitis, pancreatic blockage, salivary gland inflammation
- Normal amylase: pancreatic enzyme levels within expected range
- Low amylase: rarely significant, but may be seen in chronic pancreatic disease
Amylase results are often interpreted alongside lipase, liver tests, and clinical symptoms for accuracy.
