Hello Doctor, I did Fecal Calprotectin and below is the result. What does it signifies.  The gastro even did endoscopy and Ultrasound and it came as normal. But every few days I feel like dull pain in different parts of abdomen and it will go away on its own. In the next visit, he didn't even give importance and said just be relax and don't take stress. Calprotectin : µg/g NA Method: Enzyme Linked Immunosorbent Assay Negative (12.15) Interpretation : ------------------------------------------- Negative       = < 43.2 µg/g ------------------------------------------ Positive            >43.2 µg/g
