Pancreatic fluid analysis for cytology and pathology (guided biopsy)

Why This Test Is Done

Your doctor may recommend this test if you have symptoms like unexplained abdominal pain, weight loss, jaundice (yellowing of skin/eyes), or if imaging tests (like an MRI or CT scan) suggest a possible pancreatic mass or lesion. It’s also used to evaluate chronic pancreatitis or other pancreatic disorders.

What to Expect Before the Test

You’ll likely receive local anesthesia to numb the area where the biopsy will be taken. The procedure is usually done under imaging guidance (like ultrasound or CT) to ensure the needle reaches the correct spot. You may need to fast for a few hours before the test, depending on your doctor’s instructions.

During the Test

A small amount of fluid is collected from the pancreas using a needle guided by imaging. The fluid is then sent to a lab for microscopic examination to look for abnormal cells, signs of inflammation, or other issues. The process takes about 15–30 minutes.

What the Results Mean

Results can show whether there are abnormal cells (like cancer), signs of infection, inflammation, or other pancreatic conditions. If abnormalities are found, further testing (like biopsies of solid tissue) may be needed. Normal results don’t rule out all pancreatic issues, so your doctor will discuss findings with you.
