Blood Test Results Question

Hi! I recently did blood testing for celiac disease for the first time, and just received my results. What do these results indicate? My follow up appointment with my doctor isn’t for a month but I wanted to understand what my results are. 
 

any help in interrupting these would be much appreciated!

"Negative serology" means the blood test that were done did not indicate celiac disease. However, they only did one test, the tTG-IGA test which is the most specific for celiac disease. At the same time, however, the tTG-IGA is the least sensitive of the several tests that can be done to detect celiac disease and so it misses about 1/3 of those who may actually have the disease. This might help: https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

That your total IGA levels were in the normal range means that the testing is more likely to give accurate results. When total IGA levels are low, that can skew the results. 

Your test results to this point seem not to point to celiac disease but you could also be gluten sensitive. Although many of the symptoms are the same with celiac disease and gluten sensitivity, the difference is that gluten sensitivity does not damage the villi of the small bowel. Proteins given off by the damage done to the villi are what the tTG-IGA testing measures. 

Do you have more specific questions about your test results?

As @trents mentioned this particular test is negative for celiac disease. Did you have the test done because you have symptoms? If you do have symptoms you may want to do a DPG test, which is another blood test for celiac disease, and/or the genetic test that the results you shared recommends.

Last, there currently isn't a test for non-celiac gluten sensitivity, which ~12% of the population has (only about 1% have celiac disease), so after all testing is completed you may still want to try a gluten-free diet for a few months to see if it relieves any symptoms you may have.

      Basic metabolic panel results - more flags

      I have many of those same CMP irregularities from time to time, with the exception that my potassium is always normal. What I can tell you is that it is normal for everything not to be normal when you get a CMP done. I used to get a CBC and CMP done annually and there were always some things out of spec. Docs don't get excited about it for the most part....

      Self Diagnosed avoiding gluten 7 months later (Not tested due to eating gluten to test) update and question on soy

      Not sure what you mean by "soy being like gluten". Soy does not cause a celiac reaction. However, soy is one of the foods that many celiacs don't tolerate well for other reasons. Eggs, corn and dairy are also on that list of foods that many of those with celiac disease seem to be sensitive to. But that doesn't mean that all celiacs are sensitive to any one...

      Self Diagnosed avoiding gluten 7 months later (Not tested due to eating gluten to test) update and question on soy

      I know I haven't been tested but self diagnosed that by avoiding gluten the past 7 months I feel so much better. I have followed how to eat and avoid gluten and have been good about hidden gluten in products, how to prep gluten-free and flours to use to bake gluten-free and have been very successful. It has been a learning curve but once you get the hang...

What I can tell you is that it is normal for everything not to be normal when you get a CMP done. I used to get a CBC and CMP done annually and there were always some things out of spec. Docs don't get excited about it for the most part. It depends on the particular parameter (some are more important than others) and it depends on how far out of range it is. Docs also look for trends over time as opposed to isolated snapshots of this or that being out of spec at any given time. Our body chemistry is a dynamic entity.

Eggs, corn and dairy are also on that list of foods that many of those with celiac disease seem to be sensitive to. But that doesn't mean that all celiacs are sensitive to any one of them or all of them. It just means it's common. You may not have a problem with soy at all. Celiac disease is not a food allergy. It is an autoimmune response to the ingestion of gluten that creates inflammation in the small bowel lining that, over time, damages that lining.

      Hey all  Has anyone on here experienced any of the following on their basic metabolic panel results ? This is what mine is currently flagging : - low sodium  - nearly too low potassium - nearly too low chloride - high CO2  - low anion gap  This is now after being nearly gluten-free for over a year (although I admit I make mistakes sometimes and pay dearly for it). My TtG went down to undetectable. I was so sensitive to so many foods I am now avoiding meat dairy and don’t eat a lot of cooked food in general (raw veggies, white rice, avocados and boiled eggs are my usual go-to meal that doesn’t make me sick). But my abdomen still hurts, i have a range of other symptoms too (headaches that last for days before letting up, fatigue, joint pain, bladder pain). Anyway im hoping my urologist (that’s now the latest specialist I’ve seen on account of the bladder pain and cloudy urine after eating certain foods) will help me with this since he ordered this metabolic panel. But I’m bouncing around a lot between specialists and still not sure what’s wrong. Also went back to the GI doctor and she thought maybe the celiac is just not healed or I have something else going on in the colon and I should have that looked at too. I’m still anemic too BTW. And I’m taking sooo may vitamins daily.

I have followed how to eat and avoid gluten and have been good about hidden gluten in products, how to prep gluten-free and flours to use to bake gluten-free and have been very successful. It has been a learning curve but once you get the hang of it and more aware you realize how many places are gluten-free and contamination free practices etc. One thing I have read is how soy is like gluten. How would one know if soy affects you? I have eaten gluten free hershey reeses that say gluten free etc some other snacks say gluten free but contain soy and I dont get sick or soy yogurt no issues. Is there adifference in soys?

      Check your multivitamin to see if it contains Thiamine Mononitrate, which is a "shelf-stable" form of thiamine that doesn't break down with exposure to light, heat, and time sitting on a shelf waiting to be sold.  Our bodies have difficulty absorbing and utilizing it.  Only 30% is absorbed and less can be utilized.   There's some question as to how well multivitamins dissolve in the digestive tract.  You can test this at home.  YouTube has instructional videos.   Talk to your nutritionist about adding a B Complex.  The B vitamins are water soluble, so any excess is easily excreted if not needed.  Consider adding additional Thiamine in the forms Benfotiamine or TTFD (tetrahydrofurfuryl disulfide) or thiamine hydrochloride.   Thiamine is needed to help control electrolytes.  Without sufficient thiamine, the kidneys loose electrolytes easily resulting in low sodium and chloride.   We need extra thiamine when we're emotionally stressed, physically ill, and when we exercise regularly, are an athlete, or do physical labor outdoors, and in hot weather.  Your return to activities and athletics may have depleted your thiamine and other B vitamins to a point symptoms are appearing.   The deficiency symptoms of B vitamins overlap, and can be pretty vague, or easily written off as due to something else like being tired after a busy day.  The symptoms you listed are the same as early B vitamin deficiency symptoms, especially Thiamine.  Thiamine deficiency symptoms can appear in as little as three days.  I recognize the symptoms as those I had when I was deficient.  It can get much worse. "My symptoms are as follows: Dizziness, lightheaded, headaches (mostly sinus), jaw/neck pain, severe tinnitus, joint stiffness, fatigue, irregular heart rate, post exercise muscle fatigue and soreness, brain fog, insomnia.  Generally feeling unwell." I took a B 50 Complex twice a day and extra thiamine in the forms Benfotiamine and TTFD.  I currently take the Ex Plus supplement used in this study which shows B vitamins, especially Thiamine B 1, Riboflavin B2, Pyridoxine B 6, and B12 Cobalamine are very helpful.   A functional evaluation of anti-fatigue and exercise performance improvement following vitamin B complex supplementation in healthy humans, a randomized double-blind trial https://pmc.ncbi.nlm.nih.gov/articles/PMC10542023/
