Pls Help Me Understand My Prometheus Blood Test Results

Hi, I'm hoping you can help me. My GI is useless and won't call me back to explain my prometheus test results to me. I finally had to have them email me the results since he wouldn't respond. The test results say the following:

Summary Interpretation: Results do not exclude a diagnosis of celiac disease

Serological markers for celiac disease not detected.

Assay Name:

Anti-Gliadin IgG ELISA (AGA IgG) < 1.2 U/ml (Range <10.0 U/ml)

Anit-Gliadin IgA ELISA (AGA IgA) 2.2 U/ml (Range <5.0 U/ml)

Anti-Human Tissue Transglutaminase IgA ELISA (TTG IgA) <1.2 U/ml (Range <4.0 U/ml)

Anti-Endomysial IgA IFA (EMA IgA) Negative (Reference Negative)

Total Serum IgA by Nephelometry (TOTAL IgA) 254 mg/dl

Alleles Detected: DQ2 heterodimer and DQ8

DQ2/DQ8 - 14X (Increased Risk Over Gen Pop) Very High (Relative Risk)

Your help in interpreting this results would be greatly appreciated.

You have the two recognized celiac genes. Although your blood tests were negative they could be a false negative, up to 20% of us will have negative blood tests. If you are planning on having a endo and biopsy stay on gluten. If your not then do give the diet a good try and see if it helps your issues.

Thanks. My first non-prometheus blood test showed an elevated anti-gliadin IGA level of 38 H so I guess it was positive. This test above was after being gluten free for about 4 months. I also had an endoscopy which the GI specialist said was negative for celiac. I don't know what to think anymore. All I know is that my neuropathy is going away after being gluten free so it must be that. Any other thoughts?

After being gluten free for 4 months, you can't run a blood test to find celiac. You have to be eating gluten for a while (3 slices of bread a day for 3 months).

So I guess that's why the prometheus was negative since I've been gluten free? I had been gluten free for about a month when I got the endoscopy so maybe that's why it also showed up negative. Anyway, at least I'm feeling better with the neuropathy so it must be the gluten.

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      Have you tried Pure Encapsulations supplements? This is a brand my doctor recommends for me. I have no issues with this brand.

      FDA Moves to Improve Gluten Labeling—What It Means for People With Celiac Disease

      My question I have proposed to the FDA through their website is why Prescription and OTC drug manufacturers are not required to list what binding ingredients were used to bine the drug? They list this on Capsules which are made of cellulose but not on pills? As it stands I or my pharmacist must contact the manufacturer to find out and my list is long from...

      i take b12, folate, b2, b6, glycine, Nac, zinc, vk2 mk4, magnesium, coq10, pqq, tmg, creatine, omega 3, molybdnem (sp) and just started vit d. quite a list i know.  I have high homocysteine (last checked it was 19, but is always high and i finally decided to do something about it) and very low vitamin d, 10. have been opposed to this supp in the past, but going to try it at 5k units a day. having a pth test on friday, which is suspect will be high. my homocysteine has come down to around 9 with 3 weeks of these supplements and expect it to go down further. i also started on estrogen/progesterone. I have osteoporosis too, so that is why the hormones.  anyway, i think all celiacs should have homocysteine checked and treated if needed (easy enough with b vit, tmg). homocysteine very bad thing to be high for a whole host of reasons. all the bad ones, heart attack , stroke, alzi, cancer..... one of the most annoying things about celiacs (and there are so many!) is the weight gain. i guess i stayed thin all those years being undiagnosed because i was under absorbing everything including calories. going gluten-free and the weight gain has been terrible, 30#, but i'm sure a lot more went into that (hip replacement - and years of hip pain leading to inactivity when i was previously very active, probably all related to celiacs, menopause) yada yada. i seemed to lose appetite control, like there was low glp, or leptin or whatever all those hormones are that tell you that you are full and to stop eating. my appetite is immense and i'm never full. i guess decades or more ( i think i have had celiacs since at least my teens - was hospitalized for abdominal pain and diarrhea for which spastic colon was eventually diagnosed and had many episodes of diarrhea/abdominal pain through my 20's. but that symptom seemed to go away and i related it to dairy much more so than gluten. Also my growth was stunted, i'm the only shorty in my family. anyway, decades of malabsorption and maldigestion led to constant hunger, at least thats my theory. then when i started absorbing normally, wham!! FAT!!!
