Intestinal Goblet Cell IgA, Serum, Qualitative

What This Test Measures

The test detects immunoglobulin A antibodies directed against goblet cells, which are the mucus-producing cells lining the intestine. A qualitative result simply reports whether these antibodies appear to be present or absent rather than giving an exact amount.

Why It May Be Ordered

Your clinician may order this test when trying to evaluate chronic diarrhea, unexplained intestinal inflammation, or a suspected autoimmune condition affecting the gut. It is generally used as one piece of a larger diagnostic workup rather than on its own.

How the Sample Is Collected

A standard blood draw from a vein in your arm is used to obtain the serum sample. No special preparation is usually required, though you should follow any specific instructions your laboratory or care team provides.

What Results Can Mean

A positive result suggests these antibodies are present and may point toward an autoimmune intestinal process, but it does not confirm a diagnosis by itself. A negative result makes such a condition less likely but also does not rule it out. Results are always interpreted with your symptoms, imaging, biopsy findings, and other laboratory tests.
