About Gluten intolerance. Disease?

I'm 20 yr old male and I'm Always suffering from mild lower abdominal pain and bloating. even sometimes i suffer from diarrhoea and sometimes constipation. i also feel bloated and i fart a lot too. Even I've tested myself for Gluten test(blood serum ttg) and the result is- 1. Anti transglutaminase igA antibody- 22.77 units 2. Anti transglutaminase igG antibody- 10.48 units. Even I've attached the test report. I've done colonoscopy, Ultrasound, Endoscopy, LFT, CBC test as well and these all are nearly normal. only colonoscopy shows type 1 hemorrhoid and ultrasound shows mildly prominent bowel loops. Please suggest me what should i do next? should i go for gluten-free diet or done a biopsy of my small intestine for coeliac disease?
