No worries... I feel your pain... We've dug through a lot of gut issues over time.
As long as you're doing the NutrEval, do a GI Effects test from Genova, too. Or a DiagnosTechs stool test.
You need to look at the entire digestive system from end to end... what goes in, what interacts with it and what goes out. You might look up the "4R protocol" and work through it. The Food Intolerance Bible by Anthony Hayne has been an invaluable resource to us, with lots of self-diagnostic quizzes to help you trap your problems and fix them.
Given what you've said, its likely you have one or more food intolerances inflaming your gut, and then causing leaky gut, systemic inglamnayion, autoimmunity, and translocation of genes. Not good... Getting rid of them is key.
Gluten and grains are likely suspects, even corn, quinia or rice which are supposedly gluten free. Milk, eggs, nightshade vegetables, citrus fruits, etc. can be culprits, too, as well as soy and any other crop heavily sprayed with RoundUp during cultivation/harvesting. Cyrex Labs has tests for many of these.
The health of the tissues along your digestive tract is important. Reducing inflammation caused by certain foods while repairing with nutrients is critical. Amino acids and lipids build tissue and other nutrients support the growth of healthy tissue. An oral, transdermal, sublingual, and/or IV supplement program can be helpful.
Finding and removing parasites, like h. pylori, blastocystis hominis, roundworm, tapeworm, pinworms and fungi like candida is important. Identifying the exact culprit(s) and using botanical or pharmaceutical tools with short term dietary modifications targeting them would help.
Then, you need to have adequate stomach acid, digestive enzyme production by the pancreas, and adequate bile production by the gall bladder and liver. If you don't, find out why and target the root cause and don't just bandaid the problem.
Your liver needs to work properly, with adequate nutrients to filter and metabolize what what you in jest and to rid the body of waste products from biochemical processes and toxins. If it has an infection or lacks nutrients or is overwhelmed by too big a job to do, you can be in trouble. Watching serum ferritin, AST, ALT, GGT, and looking for infections and heavy metals will identify issues, while a liver supporting nutrient protocol, including glutathione precursors (glutathione doesn't stick around long, so better to make it and recycle it steadily than to supplement it directly) is helpful in reducing unpleasant symptoms and averting serious disease.
Looking up Phase I, II, and III nutrients will help you understand the needs - here's an example...

Also, eating a high fiber diet or supplementing with prebiotics helps support waste removal.
Then, you can look at probiotics. You may need to start with very few then add to increase tolerance. And likely rotate between them. Ones that would be good to try are Xymogen ProbioMax, Pharmax/HLC High Potency, PrescriptAssist, Equilibrium, and Mutaflor or Symbioflor. You can also strategically alter your diet to encourage the good guys and discourage the bad guys, but that's an advanced topic...this is plenty to start with.
Best of luck to you (and to be clear, I'm not a doctor, just a patient like you... so I say this with all the usual disclaimers).
