Confusing Test Results

A little background: I'm 29 and had my thyroid removed last fall due to advanced Graves Disease (Hyperthyroid). My thyroid was so big it was choking me. Anyway, shortly after surgery we realized my calcium wasn't regulating itself and I've since been on 3600 mg in pill form per day and on 500 mg of Magnesium per day. I have consistent muscle cramps and spasm and lots of bone pain that were thought to be a result of the calcium levels and I still believe that. However, my endocrinologist recently decided a Celiac Blood panel was in order. These are my results. He believes me to have Celiac Disease, has referred me to a Gastro and a dietician. I'm confused how I can have negative results on two of the three test and be thought to have Celiac. Any thoughts?

 

 

 

Immunoglobulin A, QN, Serum- 167 (Range is 91-414)

 

Deamidated Gliadin ABS, IGA- 8 (Range 0-19)

 

T-Transglutaminase (TTG) IGA- 16 (Range 0-3) High Positive

The first test you list is not for celiac disease. It is for your total IgA to see if it is normal. Yours is. (If it wasn't the other two tests you list for specific types of IgA would not be valid). As to the TTG and DGP tests, some people with celiac are positive on one, some on the other, some on both.

Oh ok, so he is likely correct to assume I could be Celiac. I'm very hesitant to go forward with a biopsy. I've been through a lot medically this past year. I won't go into detail but it's been difficult. I don't know if I could handle going through that if it isn't 100% necessary. Other than being the most definitive diagnostic tool for the disease are there any other benefits to going through the biopsy process? To be frank, I'm terrified not of the result but the procedure itself. I'm fine with living gluten free regardless of the biopsy results.

Sorry to intrude, just wanted to tell you not to worry about the endoscopy/biopsy. I had one last year and I was also worried but it was easy peasy. It takes about 10 minutes and you're sedated. Then you're sent home! I understand your fears but think about now many endoscopies are performed everyday! Most older people have had them at least once and it's not really a big deal. Hope it goes well!

Thank you and you aren't intruding. I am actually declining the endoscopy for now. It's very expensive even with my insurance. It seems like it only serves as a confirmation and will tell me how extensive the damage, if any, correct? I'm not sure I want to know how much damage there is just yet. I was able to be given the diagnosis without that procedure so it kind of seems like a waste of money for me. To each their own, I just don't know that I can justify the expense of a test that is only confirmation of something my doctor is already confident I have. Plus, I read that sometimes people receive a negative result only to years later find out they do have celiac disease.

This does happen in a minority of cases. Up to 1 in 5 celiacs gets a negative biopsy.  You had a positive test, some symptoms, and an autoimmune disease that is strongly linked with celiac disease, so it is most likely celiac disease.  A positive test would just confirm, and a negative test would not disprove it, but only not support the celiac diagnosis.

 

Also, the specificity of a positive tTG igA is 95%, so only 5% of positive tests are caused by something other than celiac disease.  It's a pretty good test.

 

If you want confirmation, retest the DGP IgA and tTG IgA after 6-12 months gluten-free.  Chances are that they'll have dropped significantly.

 

Welcome to the board!  I hope you have a fast recovery.  :)

      @Jane02, I hear you about the kale and collard greens. I don't do dairy and must eat green leafies, too, to get sufficient calcium. I must be very careful because some calcium supplements are made from ground up crustacean shells. When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?
