Liver & Kidneys Fasting RequiredTurnaround: 2–4 hours (same day / STAT)

Serum Amylase & Lipase (Pancreatic Enzymes)

Also known as: Pancreatic Enzyme Panel, Serum Lipase, Serum Amylase, Pancreatitis Blood Test

Parameters Measured in the Report

A breakdown of individual biomarkers and biological reference intervals typically found in your report:

Biomarker	Standard Range	Unit	What It Means
Serum Lipase (Lipase)	10–140 (Pancreatitis threshold: ≥ 3x upper limit)	U/L	Highly specific to pancreatic tissue; stays elevated for 7–14 days following acute insult.
Serum Amylase (Amylase)	30–110	U/L	Produced by both pancreas and salivary glands; surges rapidly within 6–12 hours of acute injury.

* Note: Reference ranges may vary slightly between testing instruments and reagent kits. Always refer to the reference interval printed on your specific pathology report.

Clinical Focus

Digestive enzyme concentrations manufactured by pancreatic acinar cells and secreted into the duodenum.

Sample & Specimen

Venous blood (Serum tube)

Fasting Protocol

Fasting for 8 hours preferred, though can be drawn STAT in emergency acute abdominal pain presentations.

Turnaround Time

2–4 hours (same day / STAT)

What Is This Test?

Serum Amylase and Lipase are digestive enzymes synthesized and secreted by the exocrine cells of your pancreas to break down dietary carbohydrates and dietary fats. In a healthy state, only minute amounts of these digestive enzymes enter the bloodstream. However, during acute pancreatitis (often triggered by gallstones obstructing the pancreatic duct or heavy alcohol consumption), digestive enzymes become trapped and activated prematurely inside the pancreas itself. The resulting auto-digestion and tissue inflammation cause massive amounts of amylase and lipase to leak into the blood.

Why Did Your Doctor Order This Test?

Physicians routinely prescribe the Amylase & Lipase in the following clinical scenarios:

Sudden, severe upper abdominal pain that radiates straight through to the back, often worsened after eating or lying supine

Persistent vomiting, nausea, fever, abdominal tenderness, or guarding associated with acute epigastric pain

Follow-up monitoring of known chronic pancreatitis or suspected pancreatic pseudocysts

Evaluation of common bile duct obstruction caused by gallstones (biliary pancreatitis)

How to Prepare Before Your Test

Fasting Requirement: Fasting for 8 hours preferred, though can be drawn STAT in emergency acute abdominal pain presentations.

Overnight fasting is preferred, but do not delay emergency testing if acute severe abdominal pain is present.
Refrain from consuming alcohol for at least 48 hours prior to testing.

Understanding Your Results

What higher or lower readings generally mean in clinical practice:

If Values Are Higher Than Normal

Elevations of serum lipase and/or amylase exceeding three times the upper limit of normal (≥3x ULN) is one of the classic triad criteria confirming Acute Pancreatitis. Moderate elevations can occur in gallstone colic, bowel obstruction, mumps (salivary amylase), or renal failure due to decreased clearance.

If Values Are Lower Than Normal

Low levels are normal. Severely suppressed lipase/amylase in chronic abdominal pain suggests end-stage chronic pancreatitis where pancreatic acinar tissue has undergone extensive fibrotic destruction.

Frequently Asked Questions

Why is Lipase considered a better test than Amylase for pancreatitis?

Lipase is virtually 100% specific to the pancreas, whereas amylase is also produced in large amounts by salivary glands. Furthermore, lipase remains elevated in the bloodstream for up to 2 weeks, catching patients who present several days after pain started.

Related Laboratory Tests

Tests frequently prescribed together or used as follow-up investigations:

Liver Function Test (LFT / Hepatic Panel)

Bilirubin fractions, transaminases (ALT/SGPT, AST/SGOT), Alkaline Phosphatase (ALP), and proteins (Albumin, Globulin).

Kidney Function Test (KFT / RFT / Renal Panel)

Serum Creatinine, Blood Urea Nitrogen (BUN), eGFR (filtration rate), Uric Acid, and Electrolytes.

Complete Blood Count (CBC / Hemogram)

Counts and evaluates red blood cells, white blood cells, hemoglobin, hematocrit, and platelets.
