Suspects For IBD Chron's. Disease?

Good evening doctor's, iam having abdominal pain since last two months. I have done Upper GI Endoscopy impression " H pylori Antral Erosive". Am started having loose motions suddenly. From last two weeks. I have done colonoscopy also impression was "Normal Study". I have done ESR ,CRP & Fecal calprotectin test which is came out normal. But my abdominal pain & loose motions are not controlling. So I went For ASCA (igg & iga) & ANCA blood Test. My ANCA both P anca & C anca came out negative. But my ASCA IGA value is 4.6 & ASCA IGG value is 24.6 which is boarderline Positive for Chron's disease. But my Fecal calprotectin value is less than 10. So I am confused whether I am having IBS symptoms or not. I request you to please Help to diagnosis for my symptoms. As per doctor advise should I go for CT Enteroclysis? Is ASCA blood Test is very Sensitive test for making diagnosis of Chron's disease? Thanking you for your patience.
