Have you ever had a fecal calprotectin stool test before or would this be your 1st? I ask because the test has a 8-13% false negative/positive rating, meaning that for a small percentage of us the test is always wrong. It's 87% accurate according to the folloiwing:
The overall accuracy for the detection of endoscopically active
disease was 87% for calprotectin (cutoff 70 g / g), 66 % for elevated CRP, 54% for blood
leukocytosis, and 40% for the CDAI ≥150.
Personally, I've had a normal FCP and had very mild UC symptoms (a little bit of occasional blood, and 3-4 bms a day). If you have a little bit of lingering inflammation then it might not catch it.
