Fecal Calprotectin - Stool Quantitative CLIA
Also Known As
Test Parameters Included
- Stool Fecal Calprotectin Concentration (μg/g) - quantitative measurement of neutrophil-derived protein
- Pathologist Gastroenterology Remark - correlated with endoscopic activity and IBD monitoring intervals
Department
Methodology
The test is performed using the Chemiluminescence Immunoassay (CLIA) method. This is an advanced immunoassay technique known for its superior sensitivity and specificity. The CLIA method provides a precise quantitative result, which is crucial for monitoring disease activity and response to treatment. Key features of this methodology include:
* High Sensitivity: CLIA can detect very low levels of calprotectin, allowing for the early detection of inflammation.
* Quantitative Results: The test provides a specific numerical value (e.g., in µg/g), which allows for objective tracking of disease activity over time.
* Accuracy and Precision: The automated nature of the CLIA platform ensures high reproducibility and accuracy, minimizing the risk of human error.
Sample Required
Preparation
#2) Fresh Sample: The stool sample should be collected as a fresh sample. It is best to collect the sample in the morning and transport it to the lab as soon as possible.
#3) Avoid Contamination: Ensure the sample is not contaminated with urine or toilet water. The stool should be collected from a clean, dry surface.
#4) Sample Size: Only a small, pea-sized portion is required. Follow the instructions on the collection container.
#5) No Special Diet: There are no specific dietary or medication restrictions required before this test, but you must inform your doctor about any medication you are taking, especially NSAIDs.

Frequently Asked Questions
Is fasting required for fecal calprotectin test?
No, fasting is not required. The test can be performed on a stool sample collected at any time of day.
How is the stool sample collected?
A small pea-sized portion of freshly passed stool is collected in the provided sterile container. Avoid contamination with urine or toilet water.
What does a high fecal calprotectin level indicate?
Elevated levels suggest intestinal inflammation, commonly seen in inflammatory bowel disease (IBD) like Crohn's disease or ulcerative colitis. It helps differentiate IBD from irritable bowel syndrome (IBS).
Can certain medications affect the test result?
NSAIDs and corticosteroids may influence calprotectin levels. Inform your doctor about all medications before testing.
What is the typical turnaround time?
Results are usually available within 24-48 hours after sample receipt at the laboratory.
