Test Results

[Sasquatch]

I got the results back from my blood test today, and the Gliadin Antibody IgA and Tissue Transglutaminase IgA were negative, but the Gliadin Antibody IgG was a bit positive (It was 16 when normal is <11). The total IgA was below normal (It was 54 when normal is 80-450). The doctor called it inconclusive and I have a biopsy scheduled for Thursday. He also said that although they used to think the tissue transglutaminase was 99% effective, they now only think it's 90%. I am just confused about what the total IgA actually is, it was my most unusual. What does a defeciancy of total IgA mean?

I think you have IgA deficiency because the total IgA is used to rule it out but that was low. That can make your otherwise positive tests come back negative.

As fr as tTG goes...that is a wonderfully accurate test that is pretty good for detecting damage, soon to take place of biopsies in at least children for diagnosis.

A test they didn't test you for is EMA which is another pretty good test to help detect damage. Not as good as the tTG but the next best thing.

I was looking at more at my blood test results and noticed another abnormality. Although it isn't specifically with a celiac test, I think it might be related. I got tested for the TSH thyroid test, which I also had done in May. In May, it was 2.81, and now it was 3.31 (normal is 0.34-2.50) Although is says my values are not too abnormal, I thought it was a little strange because, if I understand it right, a higher TSH value means lower thyroid activity, then mine is on the low side. However, I've heard that lower thyroid activity causes a slow metabolism and weight gain, but I'm extremely skinny and unable to gain weight. I've always been thin and thought I must just have a fast metabolism, but according to the test it's getting to be slow, but I'm still not gaining weight.

Your values are only minimally high so maybe you don't see the effects yet. Yes a high TSH means low thyroid function and you need to keep an eye on your levels. There are also exceptions to every rule so you might be a thin person with hypothyroidism. I would get the full thyroid panel done....free t3, free t4, and another TSH. There are other thyroid tests but these are the best to determine function. Hope this helps

[SueC]

oops.....The best thyroid tests are Total T3, Total T4, and TSH....... The free T3 and free T4 can be affected by alot of non-thyroid stuff......

Actually the best tests ARE the FT4 & FT3 because these show whats actually *available* in the body....some of the hormones are *stored* and not free for the body to use. Not sure if I explained that very well

You can still be Hypothyroid and thin...just the same as a hyperthyroid person can be overweight. There are no rules...but yes its more *typical* to be overweight as the metabolism slows down. Your numbers should be watched because they are on the hypo end as mentioned previously. I was Hyperthyroid but after taking radioactive iodine I went Hypo (which is the point). My TSH was at 23.5 and I didn't gain a bunch of weight...I've always been pretty small and that didn't change when I went Hypo.
