> 400 ug/g ↑ [<10]Quantitative faecal immunochemical test

Had a calprotectin test that's come back normal.  But my fit is above high.

What does this mean? Dad and paternal Grandmother had bowl cancel I've had polyps 9 years ago didn't get a call back for a colonoscopy they missed me off! So I'm extremely concerned as I've had constant diarrhea for 2 weeks previously really constipated now I'm constipated again.
