Amylaseiso7pnlser
This test measures different forms of amylase enzymes in your blood to help determine if elevated amylase is from the pancreas or salivary glands.
{"Measures specific amylase enzymes from pancreas and salivary glands","Helps diagnose the cause of abdominal pain and enzyme elevation","Differentiates between pancreatic and salivary gland conditions","Requires a simple blood draw","Results help guide treatment decisions"}

What is this test?
The Amylase Isoenzyme 7 Panel is a blood test that measures different forms (isoenzymes) of amylase, a digestive enzyme that breaks down carbohydrates. This panel specifically separates pancreatic amylase (produced by the pancreas) from salivary amylase (produced by salivary glands), helping doctors determine the source of elevated enzyme levels.
Why do I need this test?
Your doctor may order this test if you have symptoms like abdominal pain, nausea, or vomiting, and routine blood tests show elevated total amylase. By measuring specific isoenzymes, the test helps distinguish between pancreatic conditions (such as pancreatitis, pancreatic cancer, or pancreatic injury) and salivary gland conditions (such as mumps, salivary gland infection, or blockage).
How is the test performed?
A healthcare professional will draw a blood sample from a vein in your arm. The sample is then sent to a laboratory where specialized equipment measures the different amylase isoenzymes. You do not need to fast for this test, but follow any specific instructions from your doctor.
What do the results mean?
Elevated pancreatic amylase suggests pancreatic inflammation, injury, or disease. Elevated salivary amylase indicates issues with salivary glands. Normal or mildly elevated levels in both may suggest other causes. Your doctor will interpret results based on your symptoms, medical history, and other test findings.
Are there any risks?
The risks are minimal and include slight bruising, bleeding, or infection at the puncture site. Some people may feel dizzy during or after the blood draw.
