Blood Tests Accurate?

my chiropractor thinks i have a gluten sensitivity and wants me to take a blood test to see. the tests are covered by insurance and are expensive. i went to an allergist/immunologist and she said that they did not off allergy blood tests, only skin tests and only test for allergies that are life threatening, as in throat closes after eating the food, etc. she said the blood tests for allergy sensitivities are inaccurate and a waste of money. any opinions here? how were you diagnosed? was it a blood test? what doctor gave the test? was is covered by insurance? thanks!

Hi there!

I am new here also but have done A LOT of research on this very topic!! I think that if you get a positive blood test they are something like 90% accurate. But you have to keep eating gluten so it is in your system before you have your blood drawn!

I think that it is the negatives that are inaccurate. False negatives are common with Celiac Disease

Hope this helps and like I said I am new to this (still waiting on my Celiac Panel results) and I know someone who knows more will be along shortly to better answer your question!!

Take Care!!

:D

Celiac is not an allergy so it won't show up with allergy tests. Your regular doctor can do a celiac panel. However they have a false negative rate of 20 to 30 percent. False positives are virtually unheard of so it the panel is positive you need to be gluten free. If celiac is suspected stay on gluten until the testing is finished and then after all testing is done go gluten free for a couple of months no matter what the test results.

There are some allergists who will deal with intolerances but you need to ask on the phone before you make the appointment. My allergist saved my life by putting me on a very strict elimination diet. When gluten was added back in I had a severe reaction and he then referred me back to my GI doctor who demanded another challenge. The result of that second challenge was an even more severe reaction but I finally got diagnosed. Although I was a 'test book celiac' I don't show up in blood work so that delayed my diagnosis for many years as all my doctors trusted those tests to absolutely rule it out.

      Can food allergies like milk and soy flatten villi?

      By knitty kitty · Posted

      @Matt13, Your symptoms sound similar to the ones I had.  I had developed nutritional deficiencies, in particular, thiamine deficiency.  Gastrointestinal BeriBeri has all those symptoms and the fatigue was horrible.   Quick field test from WHO:  can you rise unaided from a squat?   If you have a serious thiamine deficiency, you cannot stand back up after squatting.  Really cool test.  Read for yourself the article below, compare the symptoms, discuss with your doctors.  Doctors can administer high dose thiamine via IV and you will improve very quickly.  I had improvement within an hour.  No harm in trying, process of elimination and all that. Thiamine is safe and nontoxic even in high doses.   Thiamine deficiency disorders: a clinical perspective https://pmc.ncbi.nlm.nih.gov/articles/PMC8451766/ Are you aware regular Ensure Plus contains dairy?  Are you aware Plant Protein Ensure Plus contains oats?  Just checking.   Have you tried the AutoImmune Protocol diet?  Highly recommend.   Check out my blog to read excerpts of my journey and my clueless doctors. Keep us posted on your progress!

      What might this EMA result mean?

      By RMJ · Posted

      g/L, a weight per volume unit, would be a very unusual unit for a celiac specific (EMA) test.   1.24 g/L would be in the normal range if this was a TOTAL IgA test. Best to ask the doctor.

      Searching for good MD/PCP in Portland ME Area

      By Lieke · Posted

      Hi Hi! I am looking for a PCP in the Portland ME area. I have been dealing with Celiac disease for 30 years. My specialist Celiac MD is in Boston, but I want somebody closer by. Am thinking of an MD working in functional medicine/integrative medicine who is willing to ‘walk the journey’ with me. Despite a strict gluten-free diet, I still have challenges, am ‘super sensitive celiac’ with at time cross contact issues when going out to dinner.  any suggestions?  much appreciated! lieke

      Food Tasting Salty

      By knitty kitty · Posted

      Part of the body's immune reaction to gluten is to release histamine.  This tastes salty, just like tears and snot.

      Eye irritation 2.5 months into gluten free diet

      By knitty kitty · Posted

      I've had dry eye symptoms.  The eye drops did not help me.  What did help was making sure I was consuming Omega Three fats like flax seed oil and olive oil, and taking essential B vitamins, especially Riboflavin, Thiamin, and Vitamin C, as well as Vitamin A, one of the fat soluble vitamins.   Newly diagnosed Celiac can have trouble absorbing fats and absorbing B vitamins.  Most gluten free processed foods contain saturated fats which the body can't utilize. Gluten free processed foods are not enriched with vitamins like gluten containing products.  The eyes make a film of healthy omega three fats which keeps the eyes lubricated.  Insufficient omega threes can show up as dry eyes.  Most newly diagnosed Celiac are low in Vitamin D, as well as Vitamin A, both fat based vitamins.   Thiamin Vitamin B 1 and Riboflavin B 2 are needed for eye health and optic nerve health.  Taking a B Complex vitamin supplement is beneficial.  Since the B vitamins are water soluble, any excess that the body doesn't need is excreted easily in urine.  The gluten free diet is low in essential B vitamins because gluten free processed foods that replace gluteny breads are not required to have vitamins and minerals added to them in order to replace vitamins and minerals lost in processing as is required with gluten containing products.   Other things that are helpful is to refrain from using highly perfumed products (hair care, body washes, deodorants, room fresheners, cleaning products, etc.).  These can dry out the eyes, too.   Staring at computer screens can be detrimental because you STARE and don't blink.  The tear ducts that keep the eyes lubricated are in the corners of the eyes.  Take breaks from staring at the computer screen.  Look out of the corners of your eyes to the right and blink several times, then look to the left and blink to help the tears spread over the whole eye.   My eyes have sustained permanent damage because of nutritional deficiencies.  My ophthalmologist and my doctors did not connect any of my health problems with nutritional deficiencies which occurred with undiagnosed Celiac Disease.  My optic nerve shuts down and I lose my vision if I spend too much time looking at computer screens, led lights, and TV.  My vision goes gray and dim.  It's much worse than "optic snow".  It can take  hours or days for my vision to return.  My ophthalmologist said my vision might not come back from that sometime.  My ophthalmologist said the flash rate, refresh rate, is registered by the optic nerve which gets over stimulated and shuts down.  The optic nerve uses lots of Thiamine.  Thiamine insufficiency will cause permanent optic nerve damage unless corrected promptly.  My thiamine insufficiency/deficiency was not corrected promptly and I have this permanent damage and light sensitivity.  I take Benfotiamine, a form of Thiamine that also is beneficial for healing the intestinal tract.  Riboflavin,  Pyridoxine B 6,  and Vitamin A are also needed for eye health.   Thiamine insufficiency can also cause anxiety.  Thiamine and magnesium will relieve muscle cramps. Talk to your nutritionist and doctor about supplementing with essential vitamins and minerals while your intestines are recovering.  Hope this helps!
