Advice on blood test results

[will4318]

Hi, 

I have had problems with tiredness stomach pain for years and every time I see a doctor they suspect Coeliac or Crohns so they do some tests but it all comes back negative.

I saw the doctor last week and they found that i was mildly anaemic despite taking supplements so they wanted to test for Coeliac again. 

I got my blood tests back today and I could do with some advice on interpreting them.

The results are;

Serum tissue transglutaminase Level = Negative

Immunoglobulin A level - 0.9 g/L

Do these results rule it out? or do you think I should ask for more tests? 

 

Thanks

 

Will

The full celiac panel includes:

TTG IGA
TTG IGG
DGP IGA
DGP IGG
EMA
IGA

You have to be eating gluten daily for 12 weeks before the blood test. A positive on any one blood test should lead to a gastroenterologist doing an endoscopy /biopsies to confirm a celiac diagnosis. Many people wiith celiac will only show a high  on one of the blood tests.

Thanks,

So if I have symptoms then I guess it's worth trying to get the rest done. 

Also as a side note out of interest anyone know if there iga levels vary much, have I have been tested 3 times over 5 years and everytime its 0.9g/l
