Eosinophil count in stool (qualitative or semi-quantitative)

What Is This Test Measuring?

Eosinophils are a type of immune cell that can appear in stool when there is inflammation, infection, or an allergic response in the gastrointestinal tract. This test helps identify whether these cells are present, often as part of diagnosing conditions like inflammatory bowel disease, parasitic infections, or food allergies.

When Might You Need This Test?

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, weight loss, or unexplained blood in your stool. It may also be used in cases where other tests suggest an allergic or inflammatory process in the intestines.

How Is the Test Performed?

A small sample of your stool is collected, typically through a simple stool collection kit provided by your doctor. The sample is then examined under a microscope or tested using a qualitative method to detect eosinophils. Results are usually reported as either positive or negative for eosinophil presence.

What Do the Results Mean?

Positive results indicate an increased number of eosinophils, which may suggest conditions such as eosinophilic gastroenteritis, parasitic infections, or certain food allergies. Negative results mean no significant presence of eosinophils was found. Follow-up testing or additional evaluation may be needed to determine the exact cause.
