Digestive symptoms such as persistent diarrhoea, abdominal pain, bloating, or blood in the stool can sometimes indicate inflammation within the intestines. A calprotectin test is a simple, non-invasive test to help diagnose intestinal inflammation. It aids in distinguishing inflammatory bowel diseases from functional digestive disorders.
Read on to know the faecal calprotectin test price, normal results, and the significance of abnormal stool levels.
| Particulars | Details |
| Also Known As | The stool calprotectin test is also known as a faecal calprotectin assay, faecal inflammation test, calprotectin test, or stool calprotectin test. |
| Purpose | To determine whether inflammation is present in the intestines. |
| Preparation | Certain medications, particularly non-steroidal anti-inflammatory drugs (NSAIDs), may influence results. Follow your doctor’s specific instructions. |
| Fasting Required | No fasting is required before the test. |
| Report Availability | Results are usually available within 1–5 days, depending on the laboratory. |
| Cost | INR 1,500 – INR 4,000 |
The faecal calprotectin test is a non-invasive diagnostic test used to measure calprotectin levels in stool. When inflammation occurs in the intestines, a protein called calprotectin is released by white blood cells. Determination of faecal calprotectin levels allows healthcare providers to differentiate inflammatory bowel disease (IBD) symptoms from non-inflammatory symptoms, like irritable bowel syndrome (IBS).
Measuring calprotectin in faeces allows doctors to obtain important clues about the state of the digestive tract without needing to perform a colonoscopy. The test requires only a small stool sample, which can be collected in the morning in most cases.
Your doctor might order a calprotectin stool test if you have any of the following symptoms:
The calprotectin test looks for inflammation in the digestive tract by measuring the amount of calprotectin in a stool sample.
A faecal calprotectin test is commonly recommended for individuals with symptoms such as diarrhoea, abdominal pain, unexplained weight loss, or blood in the stool to assess for intestinal inflammation. The test identifies whether the bowel disease is inflammatory or not. It can be used to differentiate inflammatory bowel diseases from non-inflammatory bowel diseases such as irritable bowel syndrome.
The findings can also assist medical practitioners in preventing unnecessary invasive treatments, especially if there is little likelihood of inflammation. If faecal calprotectin is high, further tests may be advised to find out what is causing this. On the other hand, normal results generally suggest the absence of significant intestinal inflammation, though mild or localized inflammation cannot be entirely excluded.
The cost of a faecal calprotectin test is not fixed and may vary from place to place based on several factors. Knowing these could make it easier to evaluate the entire cost of the calprotectin test.
The results of a faecal calprotectin test indicate the degree of inflammation present in the intestines.
An elevated stool calprotectin level may indicate intestinal inflammation (enteroinflammation), such as Crohn's disease, ulcerative colitis, rarely in colorectal cancer, or gastrointestinal infections.
Moderate (borderline) levels are usually signs of minimal to no inflammation in the bowel and can suggest other non-inflammatory bowel conditions, such as IBS.
| Interpretation | Calprotectin Level (μg/g) |
| Normal (Low – No Inflammation) | 49 μg/g or less |
| Moderate (Borderline Elevated) | 50–120 μg/g |
| High | 121 μg/g or greater |
The appropriate course of action after a faecal calprotectin test depends on your results and should always be interpreted in the context of your symptoms and medical history.
A score of 49 micrograms per gram (µg/g) or below is usually normal. In these situations, lifestyle changes (such as changes in diet, stress management, or regular exercise) can be used as a form of self-care to help manage symptoms.
If it is not accompanied by alarming symptoms and there is no inflammation, a doctor can make a diagnosis of IBS and recommend dietary changes and medications to help relieve symptoms, including antidiarrheals or antispasmodics.
Levels of 50 to 120 micrograms per gram (µg/g) are considered moderately elevated and may require further testing or evaluation by a healthcare provider. Repeat sampling may be necessary after a couple of weeks of borderline elevations. Your doctor might also prescribe medication to control symptoms and monitor changes in faecal calprotectin levels.
A result of 121 µg/g or higher indicates a higher risk of intestinal inflammation and may necessitate additional diagnostic testing to determine the cause. When high levels of calprotectin in stool are detected, further tests like colonoscopy or sigmoidoscopy may be recommended to find the cause of inflammation and determine the treatment.
A significantly elevated calprotectin faecal level may also be associated with:
If digestive symptoms last for a few weeks, consult your health care professional if:
If you've already been treated for inflammatory bowel disease and your symptoms return, your doctor might order another faecal calprotectin test to help determine whether you're having a flare-up and to confirm disease activity.
