I've read recent studies showing that fecal calprotectin test is very sensitive for ibd. true? i was only having mild sx compared to usual flare ups.

Not 100%: This value is only part of a workup. A test that is super-sensitive usually lacks specificity. The real question is, do you want to be treated for a grim, incurable disease without a pathologist's tissue diagnosis with powerful, pricey meds that can themselves do you serious harm because of a promo for a test that is still not widely accepted?
