Promethius Lab results-help with interpretation

I got mine back and it reads "Pattern Consistent With IBD"

None of the crohns markers were detected. But the pANCA were either detected or high. Results are:

AutoAntibody ELISA 93.2(result) <18.8(reference)
IFA Perinuclear pattern (Detected)
DNAse Sensitivity (Detected)

The genetic results showed two mutations detected but they were both heterozygous so I'm assuming it means only one copy of each. But there were no "Inflammation Results" that were out of range. How come? And previous to this prometheus labwork I had pANCA and ASCA done at another lab and both were not detected at all. Now I'm not denying I have IBD. My days of denial are over. lol! I have a very medical type mind and I find this all interesting. I'm wondering what the limitation to these tests are and why my results were different with this vs. the other test. Why didn't my first GI doc order this test? I practically had to beg him to do the other pANCA/ASCA tests.

I could ask my new GI to explain this but I find that when you have a lot of specific questions like this, they get annoyed. They try to dumb things down for patients and not get too deep for them. So can anyone here help me with my questions?

I've done about a month of Rowasa. The new GI told me to taper down to every other night but to take Canasa every day until my next appt(which is in two weeks). I could only assume I'll be on some type of maintenance dose. My biggest issue is having to watch the constipation. I have to figure out if I'm better off taking a fiber supplement or taking miralax. When I'm constipated, that tends to start a flare for me.
