Pancreatic Fluid for Gram Stain

Specimen Required

Cystic Fluid

Fasting Required

Purpose of the Test

A pancreatic fluid gram stain is a laboratory test used to detect the presence of bacteria in a sample of pancreatic fluid.

When this test is required

The test may be requested by a healthcare provider if a person has symptoms of a pancreatic infection, such as abdominal pain, nausea, vomiting, fever, or jaundice. The test may also be used to monitor the effectiveness of treatment for a pancreatic infection or to identify the cause of recurrent infections.

What the Test Detects

A pancreatic fluid gram stain is a laboratory test used to detect the presence of bacteria in a sample of pancreatic fluid.

Preparation for the Test

No special preparation is typically required for a pancreatic fluid gram stain, although the person performing the ERCP may provide specific instructions for preparation and fasting before the procedure.

Sample Requirements

To perform the test, a healthcare provider will collect a sample of pancreatic fluid during a procedure called an endoscopic retrograde cholangiopancreatography (ERCP). During an ERCP, a flexible tube with a camera on the end is inserted through the mouth and into the small intestine to visualize the pancreas and collect a sample of fluid.

Additional Notes

If the test results are positive, it means that bacteria are present in the pancreatic fluid, and further testing, such as a bacterial culture and sensitivity test, may be necessary to identify the specific type of bacteria and determine the best course of treatment. It is important to note that a pancreatic fluid gram stain is just one test that is used to diagnose pancreatic infections, and other tests, such as a bacterial culture or sensitivity test, may also be necessary to identify the specific type of bacteria and determine the best course of treatment. Additionally, the test is not always accurate, and false negatives and false positives can occur. Therefore, the test results should be interpreted in conjunction with other clinical and laboratory findings.
