Help with bloodwork numbers


CdnAmy

Recommended Posts

I’m a recent join to this wonderful forum.

I am a 52 yo perimenopausal mom of three teenagers. 

I have been gluten sensitive for several years and finally convinced the doc to run some blood work. 
 

I was eating gluten for about 2 weeks prior to the testing. My Immunoglobulin IgA result was 1.72. My ferritin, and hemoglobin were also very low. And I am borderline hypothyroid.

Does the IgA level suggest anything regarding gluten sensitivity vs celiac?

Thanks!

Welcome to the forum, @CdnAmy!

The raw score for your Immunoglobulin IGA is not very helpful without the reference range used by the lab doing the analysis. There is no industry standard for these ranges. So, please include the range for negative vs. positive. Was this the only antibody test run for celiac disease?

Consuming gluten for only two weeks prior to the test blood draw is inadequate and will not likely give a valid test result if you were gluten free prior to that for a significant amount of time. Guidelines for the pretest gluten challenge have recently undergone revision and there is no widespread agreement on how much gluten/wheat should be consumed for how long but we can say that there is agreement that it needs to be higher amounts for longer than had been formerly advised. Smaller amounts of wheat/gluten consumed require doing so for a longer period of time for the pretest challenge. I found this but not sure of the datedness of the info: https://www.celiac.ca/healthcare-professionals/diagnosis/gluten-challenge/

Your low hemoglobin and ferritin suggest celiac disease as opposed to NCGS.

Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy:

Quote

"...in order to properly diagnose celiac disease based on serology and duodenal histology, doctors need patients to be on gluten-containing diets, even if they are causing symptoms, and this is called a "gluten challenge."

  • Eat gluten prior to celiac disease blood tests: The amount and length of time can vary, but is somewhere between 2 slices of wheat bread daily for 6-8 weeks and 1/2 slice of wheat bread or 1 wheat cracker for 12 weeks 12 weeks;
  • Eat gluten prior to the endoscopic biopsy procedure: 2 slices of wheat bread daily for at least 2 weeks;

and this recent study recommends 4-6 slices of wheat bread per day:

      @plumbago, I found a good PDF on cholesterol:  Unlocking the mysteries of VLDL: exploring its production, intracellular trafficking, and metabolism as therapeutic targets I just started it, but it may have answers for us, with whacky cholesterol.  The pharmaceuticals don't seem to be interested in anything but statins.   "The nicotine in tobacco causes a decrease in the HDL cholesterol level. " Maybe you should start smoking? 🤪 I have high LDL and low HDL.  It is genetic mutations in the LDLR, APOB, PCSK9, or LDLRAP1 genes. My whole family is on statins for Familial Hyperliperdemia except me.  December I had ultrasound and cat scan for Carotid Artery blockage and both sides are above 85% blockage.  I started on Atorvastatin and that made me weaker than ever, even with CoQ10.  I asked for and got prescription for 2000 mg/day Nicotinic Acid B3 and in the 3 weeks my numbers changed. I am feeling realy good lately.  Stronger and more flexible.  Sleeping better.  Getting roto router (TCar) as soon as I get clearance from a cardiologist.  I expect that by my next blood panels in April to be even better. I am beginning to believe that like vitamin D where the RDA only accounts for preventing Rickets, the RDA for B3 is way underestimated.   From Oct 22 to Jan 17: A1c from 13.5 to 10.2 eGFR from 55 to 79 Triglyeride from 458 to 362 Total cholesterol from 245 to 264 HDL from 27 to 44 VLDL from 84 to 68 LDL from 134 to 154

      I have taken thiamine on and off (just not at this exact moment), and I’m not sure it's made any difference. Yes, I almost always “fast” (12 hours NPO) for blood tests, as do a great many other Americans, so I tend to think that’s not it. All I can say is that the mystery continues. I could do some speculating here…well, heck, let me go ahead and speculate now: The lab ranges we all see on our reports are more or less the averages of Americans who have had those blood tests. Now, it’s up to you and me whether or not to think of the average American as healthy. I can make arguments both ways, more often than not, on the negative. My point here is that maybe the current range of HDL is somewhat skewed (ie, low), and maybe just maybe my super high (plus 100s) HDL results are not something to worry about; the range just needs updating. Why do I say this? Because pre-celiac disease diagnosis, my HDL values were in the normal range, but post celiac disease diagnosis, my HDL levels are way above average. See where I’m going? My trusty guidebook on celiac disease, Recognizing Celiac Disease by Cleo Libonati, RN, BSN, says that HDL increases after being on the gluten free diet. Or can increase, I guess. Then again, it could be something else. ¯\_(ツ)_/¯ In thinking of going to a cardiologist, I sort of fear that he/she will be dismissive of a link to celiac disease, treated celiac disease, and would not therefore be considering all possibilities. @trents I'm sorry you've been diligently working on your numbers to no effect. That must be frustrating. LDL is a world that is far better understood than HDL, so for you there's maybe less "mystery." Familial hypercholesterolemia is for sure something that can be tested. Outside of that, you're right, genetics can determine a general pattern.

      Well, I have the opposite problem. My LDL has been moderately high for years. I eat healthy and exercise regularly but can't seem to move that meter. I used to be on a statin (and my doctors want me to go back on one) and it brought both HDL and LDL down but the ratios never changed. I think a lot of that cholesterol stuff is just baked into the genes.

      Wow, @plumbago, Curiouser, and curioser... Have you been fasting?  Apparently HDL levels increase after fasting... https://ajcn.nutrition.org/article/S0002-9165(23)31185-7/abstract   I must say it, try taking some Thiamine.  Thiamine helps regulate lipoproteins... Thiamine helped lower HDL in this study whether they had diabetes or not. https://pmc.ncbi.nlm.nih.gov/articles/PMC3921172/#:~:text=Serum thiamine and its derivatives,supplementation (p %3D 0.009).

      Welcome to the forum, @Tyoung! I would assume for the time being that the mild gastritis and the celiac disease are connected and that once you get a good handle on gluten free eating and experience significant healing in the lining of your duodenum, you will also see improvement in the gastritis as well. Gastritis is more often than not an accompanying finding that is commented on in the post scope/biopsy notes when people are positive for celiac disease.
