When the pancreas is damaged, these digestive enzymes can be found in the blood at higher levels than normal. Amylase or lipase results more than three times normal levels are likely to mean pancreatitis or damage to your pancreas. However, in rare cases, there can be significant damage to the pancreas without abnormal amylase or lipase levels.
What are the common causes of low amylase levels?
The following diseases can explain an amylase level in the blood lower than normal:

There are several reports in the literature of pancreatitis without elevation of amylase. However it is extremely rare not to have elevations of serum lipase.
Can you have normal lipase and still have pancreatitis?
Both patients also met the criteria for severe acute pancreatitis. The current practice in the medical field is to rule out pancreatitis if the serum lipase levels are normal, but the current case series shows that patients can have severe pancreatitis in absence of elevated amylase and/or lipase levels.
Is amylase normal in chronic pancreatitis?
High levels High amylase levels are typically a sign of acute or chronic pancreatitis.
What is the most accurate test for chronic pancreatitis?
Computed tomography (CT) is considered the best initial imaging test in the workup for CP. Advantages of CT scans are that they are widely accessible, show a detailed view of pancreatic morphology changes seen in CP, and are especially useful in detecting changes seen in advanced disease.

What can mimic chronic pancreatitis?
Chronic pancreatitis can mimic peptic ulcer disease, gastritis, and other gastrointestinal conditions, making it difficult to diagnose. However, an endoscopic pancreatic function test that Duke is one of only a few medical centers in the country to offer can help to better identify the indolent inflammatory condition.

Does lipase have to be elevated in pancreatitis?
Higher than normal levels of lipase mean that you have a problem with your pancreas. If your blood has 3 to 10 times the normal level of lipase, then it's likely that you have acute pancreatitis. High lipase levels also mean you may have kidney failure, cirrhosis, or a bowel problem.
Can a full blood count detect pancreatitis?
Other tests that may be used to check for complications of acute pancreatitis include: Full Blood Count (including white blood cell count) Glucose. The full blood count, electrolytes, and liver function tests are typically normal in chronic pancreatitis.
How accurate is lipase over amylase?
Receiver operator curves showed improved diagnostic accuracy of lipase over amylase using lipase >208 U/L, (normal< 190 U/L). 20% of patients did not have elevated amylase on their initial ED visit, while only 3% did not have an elevated lipase.
Can EM doctors stop ordering amylase?
This information is apparently so common knowledge that there is actually a paper [11] published on the best way to stop EM doctors from ordering amylase. One analysis showed 93% of patients with lipase ordered had amylase ordered as well pre-intervention. An educational intervention was unsuccessful at decreasing the concomitant ordering of amylase! Only by removing amylase from the order sets, did they find a significant decrease in amylase orders – down to 25%. Removing it from the pre-set “trauma labs” labs lowered it even more – to 14%.
Does lipase increase sensitivity?
One study [8] that validated lipase’s increased sensitivity compared to amylase also discovered that evaluating the amylase level in addition to the lipase level “does not enhance discrimination of acute pancreatitis”.

Amylase [4] levels rise less high and less often, and return to normal sooner in alcohol pancreatitis compared to gallstone pancreatitis. Amylase [5] levels are often spuriously normal in cases of hypertriglyceridemia induced pancreatitis. Lastly, one study [6] found a 91% decrease in amylase production vs a 26% decrease in lipase production in ...
Is lipase better than amylase?
Stop ordering an amylase level. Of the two tests for pancreatitis, lipase is better. Adding an amylase to the lipase does not help. Education interventions such as lectures (or writing a blog about it), does not seem to reduce ED physicians ordering amylase. A more effective stratagem seems to involve removing from the electronic medical order sets.
Is lipase elevated in HIV?
According to a review article [6], serum amylase is elevated often in: Unfortunately in comparison lipase is also elevated in HIV, diabetic ketoacidosis, bowel obstruction/infarction, and renal failure – a shorter list, but still not 100% specific.
How long does lipase stay elevated in pancreatitis?
In acute pancreatitis, amylase can rise rapidly within three to six hours of the onset of symptoms and may remain elevated for up to five days. Lipase, however, usually peaks at 24 hours with serum concentrations remaining elevated for eight to 14 days.
Which is better amylase or lipase?
There are several cases where the lipase test is often preferred over the amylase test. In the case of hyperlipidemic acute pancreatitis, lipase offers a better diagnostic accuracy of 91.8% than amylase (40.3%) , .

What labs are decreased with pancreatitis?
Acute pancreatitis is diagnosed if the lipase level reaches 3 times above the upper limit of normal. As chronic pancreatitis gets worse, lipase levels may be normal or decreased. Amylase—this is an enzyme that helps digest carbohydrates. While the amylase test is sensitive for pancreatic diseases, it is not specific.
Can you have high amylase and normal lipase?
When levels of lipase and amylase are higher than normal it may indicate pancreatic injury or another disease. Most studies show that levels of greater than three times the upper limit of normal usually lead to a diagnosis of pancreatitis, according to guidelines from the American College of Gastroenterology (ACG).

Is lipase a good screen for acute pancreatitis?from pubmed.ncbi.nlm.nih.gov
Recent literature suggests that serum amylase levels are not an appropriate screen for the diagnosis of acute pancreatitis because specificity and sensitivity are poor. Evidence from several studies supports the use of lipase determinations to diagnose acute pancreatitis, and recent improvements in this assay have made it more readily available to the emergency physician. This retrospective review compares the use of serum amylase to lipase levels in the diagnosis of acute pancreatitis in 52 patients who presented to the emergency department, with the hospital discharge diagnosis serving as the gold standard to which the assays were compared. Serum lipase was found to be more sensitive than serum amylase (95% vs 79%); serum amylase levels decreased to normal significantly faster than lipase levels.
