The calprotectin stool test is a non-invasive diagnostic tool that measures calprotectin, a protein in stool, to assess bowel inflammation levels, aiding in IBD diagnosis and monitoring.
What is the Calprotectin Stool Test?
The calprotectin stool test is a diagnostic tool that measures the level of calprotectin, a protein produced by neutrophils, in a stool sample. Elevated levels indicate intestinal inflammation, often associated with inflammatory bowel disease (IBD). It is a non-invasive, straightforward test that helps differentiate between inflammatory and non-inflammatory bowel conditions. The test is widely used for diagnosing and monitoring conditions like Crohn’s disease and ulcerative colitis, providing valuable insights into gut health and inflammation status.
Purpose of the Test
The primary purpose of the calprotectin stool test is to detect and measure intestinal inflammation, aiding in the diagnosis of inflammatory bowel disease (IBD) and distinguishing it from non-inflammatory conditions. It helps assess disease activity, monitor treatment effectiveness, and guide clinical decisions. The test is also used to screen for IBD in patients with gastrointestinal symptoms and to evaluate the severity of inflammation in those already diagnosed, providing a reliable and non-invasive method for ongoing management and care.

Proper Storage Conditions
The stool sample should be stored in a sealed container and refrigerated at 2-8°C if not immediately transported to the lab. Avoid exposing the sample to direct sunlight or heat. If transport is delayed, freezing the sample is recommended to maintain calprotectin stability. Ensure the container is tightly closed to prevent contamination. Always follow the laboratory’s specific storage instructions to guarantee accurate test results.
Transporting the Sample to the Laboratory
The stool sample should be transported to the laboratory in a sealed, labeled container to avoid leakage or contamination. If refrigeration is unavailable, the sample should be kept cold using ice packs. Avoid exposing the sample to direct sunlight or extreme heat. Transport the sample promptly, ideally within 24-48 hours of collection. If delays occur, freezing the sample is recommended to preserve calprotectin levels. Follow the laboratory’s specific shipping instructions to ensure accurate results.
Interpreting Calprotectin Stool Test Results
This test measures calprotectin levels in stool, which help assess intestinal inflammation. High levels may indicate conditions like IBD, while low levels suggest minimal inflammation. Consult your healthcare provider for accurate interpretation and next steps.
Understanding High and Low Calprotectin Levels
High calprotectin levels in stool indicate intestinal inflammation, often linked to conditions like IBD (e.g., Crohn’s disease or ulcerative colitis). Low levels suggest minimal inflammation. Calprotectin is not specific to IBD but reflects neutrophil presence in the gut. Elevated levels may require further testing, while normal levels can rule out inflammatory conditions or indicate effective treatment. Consult your healthcare provider for accurate interpretation and next steps based on your results.
Next Steps After Receiving Results
After receiving calprotectin stool test results, consult your healthcare provider to interpret the findings. High levels may prompt further diagnostic tests, such as endoscopy or blood work, to confirm conditions like IBD. Low levels may rule out inflammation, but additional testing could still be needed. Discuss treatment options or monitoring plans based on your results. The test is a valuable tool but may require follow-up to finalize a diagnosis or adjust management strategies.
Accuracy and Reliability of the Test
The calprotectin stool test is highly sensitive and specific, making it a reliable marker for intestinal inflammation. It accurately detects neutrophil presence, aiding in diagnosing conditions like IBD.
Sensitivity and Specificity of the Calprotectin Test
The calprotectin stool test demonstrates high sensitivity (95%) and specificity (79%) in detecting intestinal inflammation. It reliably identifies neutrophil presence, making it a strong indicator for conditions like IBD. While specificity improves in certain clinical contexts, the test remains a valuable tool for distinguishing inflammatory from non-inflammatory bowel diseases, aiding in accurate diagnoses and guiding treatment decisions effectively.
Limitations of the Test
The calprotectin stool test is not specific to IBD, as elevated levels can occur in other inflammatory conditions. It cannot confirm the extent or severity of inflammation. False negatives may occur if the sample size is insufficient or improper handling affects results. Additionally, variations in cutoff values across laboratories can impact interpretation. The test does not replace endoscopic evaluations but serves as a supportive diagnostic tool for identifying inflammation and monitoring disease activity effectively.
Clinical Applications of the Calprotectin Stool Test
The calprotectin stool test is primarily used to diagnose inflammatory bowel disease (IBD) and monitor disease activity, helping differentiate between inflammatory and non-inflammatory bowel conditions effectively.
Diagnosing Inflammatory Bowel Disease (IBD)
The calprotectin stool test is a key diagnostic tool for detecting bowel inflammation, common in inflammatory bowel disease (IBD). Elevated calprotectin levels indicate neutrophil presence, suggesting active inflammation. While not exclusive to IBD, high levels often correlate with conditions like Crohn’s disease or ulcerative colitis. The test helps differentiate IBD from non-inflammatory disorders such as irritable bowel syndrome (IBS). It is highly sensitive, making it an effective screening and monitoring tool for IBD, though further testing may be needed for confirmation.
Monitoring Disease Activity and Treatment Response
The calprotectin stool test is valuable for monitoring IBD activity and treatment effectiveness. Elevated levels indicate ongoing inflammation, while decreased levels suggest improvement. Regular testing helps track disease progression and response to therapy, guiding adjustments to treatment plans. This non-invasive method reduces the need for frequent endoscopies, providing a practical way to assess treatment efficacy and manage IBD effectively over time.
