Description
The lipase blood test measures the level of lipase, an enzyme produced primarily by the pancreas that helps break down fats in the diet.
Purpose of the Test
- Diagnose pancreatic disorders: Elevated lipase levels often indicate pancreatitis (acute or chronic).
- Monitor pancreatic health: Can be used to track recovery or progression of pancreatic disease.
- Detect pancreatic tumors or cysts: Abnormal levels may signal pancreatic injury or obstruction.
- Evaluate abdominal pain: Helps differentiate pancreatic causes from other digestive disorders.
How Lipase Works
- Lipase breaks down dietary fats into fatty acids and glycerol for absorption.
- Normally, only small amounts of lipase circulate in the blood.
Conditions Associated with Abnormal Levels
- High lipase levels:
- Acute or chronic pancreatitis
- Pancreatic cancer
- Gallstones blocking the pancreas
- Kidney failure (can reduce clearance, causing higher levels)
- Gastrointestinal perforation or obstruction
- Low lipase levels: Rare, but may indicate chronic pancreatic insufficiency.
How the Test is Performed
- Blood is drawn from a vein.
- Results are usually available within a few hours to a day.
Fasting Not Required (though some providers may prefer fasting to reduce variability)
This test is crucial for diagnosing pancreatic problems and monitoring treatment response.
