Test question

Questions in bold...

How long do i need to be eating gluten b4 testing? I have been having a lot of potentially unrelated issues that seem to be neurlogic in nature so I am seeing a neurologist. He says my symptoms are most consistent with MS but that has been ruled out already so he is unsure of the source. He is doing a laundry list of tests to try to find the source of my symptoms. Among them is a Gliaden antibody serum test, I was gluten-free for a few months (suspecting gluten sensitivity), went off for about a month due to financial constraints, returned to it for about a week then was told to eat normally for Gliaden antibody serum test (when I asked about it after a quick net search and it mentioned being related to celiac testing). Can the gliadin antibody serum test diagnose or indicate potential celiac or am I barking up the wrong tree? Does going gluten-free for a week affect the timetable at all on how long I need to keep gluten in my diet? I really don't want to do a normal diet any longer than I absolutely have to because whether its gluten or not SOMETHING that is removed when I am gluten-free is making a difference. TMI but for one my tummy is a hot mess and my poo is urgent, frequent, quite upleasant and cloudy. This is just one example but its a major one because it just about keeps me homebound. So any info is greatly appreciated.

A gluten challenge before a celiac antibodies testing requires about weeks of a gluten-containing diet.  It is only 2 to 4 if a person proceeds to an endoscopy to obtain intestinal biopsies.

I  would ask for a full celiac antibodies blood panel and not just the one you mentioned.  There is a reason there are several celiac antibodies tests — not everyone  tests positive to all of them and some people test negative to all of them.    In that case, an endoscopy should be ordered if celiac disease is strongly suspected.

Yep, about 12 weeks eating gluten for the blood antibody testing.
