Is a Total Serum IgA test a celiacs test ?

Hi everyone, I have akways been glutin sensative but due to other unexplained problems (that could be explained if The test is positive) I decided to ask my doctor for a celiacs test.

The only results I have back is the Total Serum IgA which is normal. Is that it or should I be waiting for more results from my blood ?

Any info or advice please as I dont want to ring the docs & ask the receptionist.

Thanks

There should be a second test to check for IGA deficiency, which checks you haven't had a false negative.

Coeliac UK have lots of info on tests if you need something to show your GP :)

Thanks I will go and have a read.

My IgA results are middle of the scale, but Im still convinced that I am.

Were you eating gluten prior to the test?

You could also have non-coeliac wheat sensitivity, which gives very similar symptoms.

I was eating mainly oats daily and wholemeal bread twice a week prior but I did have hot cross buns the day before, which made me poorly.

I have continued to have white flour in my diet just in case of biopsy but Im just getting worse so need to give it up soon

You need to eat gluten consistently, at least twice a day (e.g. toast for breakfast and a couple of biscuits for an afternoon snack) for 6 weeks prior to being tested or you can get a false negative. Oats aren't a gluten containing food unfortunately, they just have a protein similar to gluten that some coeliacs cross-react to, so we can't count them.

If you were only eating toast twice a week, you were potentially not consuming enough to cause raised antibodies for the test.

Thank you for you information, I have now started my 6 weeks intake and have done 1 week so far, however I’m not sure I can do 6 weeks, I cant keep off the toilet, any tips much appreciated.

Unfortunately there aren't any tips to help with this stage :( I've asked coeliac UK/gastroenterologists, and there's nothing they can suggest. A lot of people have to give up on the gluten challenge and live with not knowing unfortunately :(

Thanks 😊

Thanks I will call the docs & explain that I made a mistake.

I’m sure it will go down well, i may have to find a private clinic & pay for one
