My insurance now covers Quest and the lab tech said it isn't as good as the LabCorp test. My new insurance will cover LabCorp. Should I wait until I have LabCorp coverage?

My answer is that I don't know.

My celiac panel was done by Quest and it was highly positive. This was the older panel and Quest is the lab my local small town hospital uses.

My daughter in Denver uses LabCorp and had the newer DGP test. Highly positive also.

Surprisingly our results were both off-the-map positive and very similar, in fact. I do know that the DGP is newer and supposedly better.

Edit: How long will it be until you get coverage for LabCorp? That would probably influence my decision.

Thanks Sylvia, your edit is my dilemma. I have asked HR to let me know. If they say weeks, I won't make it.

Quest:

Celiac Panel Method

This panel includes a test for tTG IgA antibodies (enzyme-linked immunosorbent assay [ELISA]) and total IgA concentration (immunoturbidometry). When the tTG IgA test is positive, an EMA IgA antibody test is performed (immunofluorescence assay); if positive, the EMA titer will be determined and reported. If the IgA concentration is low, a tTG IgG antibody test will be performed (ELISA). There is an additional charge, associated with an additional CPT code, for the latter 3 tests (EMA IgA, EMA titer, and tTG IgG).

Labcorp:

Celiac Disease Complete Profile

Test Includes: Deamidated gliadin IgA; deamidated gliadin IgG; tissue transglutaminase IgA; tissue transglutaminase IgG; serum IgA quantitation

Celiac Disease Comprehensive Antibody Profile

Test Includes: Deamidated gliadin antibodies; endomysial antibodies; tissue transglutaminase (tTG) antibodies; total IgA

Celiac Disease Profile II

Immunoglobulin A; endomysial antibody IgA; tissue transglutaminase, IgA; tissue transglutaminase, IgG

Labcorp looks better to me. They do deamidated gliadin as well as the older tests. If I were getting tested I'd really want deamidated gliadin.

Yes, and it isn't "reflexive" They run them all so you can look at the results as one whereas Quest only runs the tTg IgG if the total IgA is too low.

Thanks for helping me walk through this. I would love to have my daughter get a labcorp test while eating gluten. Just to see.

If you're doing genetics LabCorp reports alpha and beta and all alleles on dq2, 8.

Good to know. As soon as I hear back from HR, I will decide if I a going to wait for the LabCorp coverage. This is for me. My Mom, Sister and I are all very curious. My sister has been plague with IBS and Endometriosis all her life and is scheduled to see the GI in Feb. I told her to get screened for Celiac based on my grandmother's history. It will be an interesting first quarter of 2012. Regardless I think we all are gluten intolerant and so does my Mom.

Thanks for the help! You just have to wonder why it is so difficult.

I will give some props to my general doc. I called about the Celiac panel and they said "you can order whatever test you want as long as you have been seen by the physician in the last 12 months. Just come on in".

How refreshing!

It's very interesting to put the familial genetics together. Comparing mine to my son's was a learning experience - especially for the doctor and hubby.

Hubs discovered HE carries at least half a Celiac gene....

Is your hubs gluten-free?

Is your hubs gluten-free?

Only at home. But it sure made him think, especially when my stepson showed up with worsening digestive issues (probably milk but the kid actually came out and said he avoids wheat products).

Unreal B)

My hubs is slowly coming around. He has 3 siblings. He and 2 siblings have severe GERD. They all take PPIs. One of them was diagnosed as gluten sensitive and her GERD has all but disappeared now that she is mostly gluten-free. Their dad died of esophageal cancer, had chronic heartburn and drinking a beer had him running to the bathroom. However, none of the other siblings, including my hubs will consider this gluten related. :rolleyes:

Well, my hubs has a cast-iron digestive system, great immune system.

He isn't so stubborn that he wouldn't do it, he just doesn't think it happens to be his problem. And he's probably right. The only problems he has ever had are high bp, and swelling ankles when he flies, and since he's gained weight as he's gotten older a bit of acidic stomach from some foods.

My stepson, on the other hand, has always been truly allergic to milk. We only see him about 1-2x a year (he's almost 21 and in college) and this time he had horrible digestive issues. He's always had issues, but this time it's over the top. It sounded like I was listening to an oral version of "do I have Celiac"? It may just be milk (and if it is he needs to give it up and now), but I almost fell over when he said he doesn't like to eat wheat.

      Raw Meat Craving

      By Jordan Carlson · Posted

      Thanks for the info @knitty kitty! I really appreciate when people recommend things for me to try, it helps a lot! I will run this stuff by my doctor at my next appointment next week. It is also good to know I am not alone with the continued reactions though. It has been pretty difficult for me and has taken a bit of a toll on my mental health. Trying so hard and dedicating so much time to resolve this issue just to feel like I am running around in circles. But i'm glad to get some insight from people who have experienced the same thing. My family and friends just keep saying i'm crazy andthat i'm a hypochondriac. But the only thing that has gotten me this far in my journey and this close to figuring it out is not listening to them and believing in myself.

      Gluten Ataxia

      Thank you for responding.  Yes I am.  Infact, sometimes I think it's getting worse. How do you deal with it? I do the best I can but it has taken away my independence.

      Gluten Ataxia

      By knitty kitty · Posted

      Hi, @Dawn R., I get gluten ataxia.  It's very disconcerting.   Are you still experiencing gluten ataxia symptoms eating a gluten free diet?

      @Jordan Carlson, Sorry to hear you're having a bumpy journey right now.  I've been there.  I thought I was never going to stop having rashes and dermatitis herpetiformis breakouts and hives, oh, my! I went on a low histamine Autoimmune Protocol Diet (AIP diet).  It gave my digestive system time to heal.  After I felt better, I could add things back into my diet without reactions.   In Celiac Disease, we make lots of histamine as part of the autoimmune response.  There's also histamine in certain types of food.  Lowering histamine levels will help you feel better.  Foods high in histamine are shellfish, crustaceans, fermented foods like pickles and sauerkraut, canned foods, processed meats and smoked meats like bacon and ham, and aged cheeses.  Grains and legumes can also be high in histamine, plus they contain hard to digest Lectins, so they go, too.  Cutting out corn made a big improvement.  Some Celiacs react to corn as though it were gluten.   Dairy can be problematic, so it goes.  Some Celiacs have lactose intolerance because their damaged villi cannot make Lactase, the enzyme that digests lactose, the carbohydrate in dairy, while some Celiacs react to Casein, the protein in dairy that resembles gluten.  Dairy is high in iodine, which makes dermatitis herpetiformis flare up badly.  Eggs are high in Iodine, too.  I even switched to pink Himalayan salt, instead of iodized salt.  Avoid processed gluten free facsimile foods like cookies and breads because they have lots of additives that can cause high histamine, like carrageenan and corn.   Yes, it's a lot.  Basically veggies and meat and some fruit.  But the AIP Paleo diet really does help heal the intestines.  My digestive tract felt like it was on vacation!   I'd throw meat and veggies in a crock pot and had a vacation from cooking, too.  Think easy to digest, simple meals.  You would feed a sickly kitten differently than an adult cat, so baby your tummy, too! Take your vitamins!  It's difficult to absorb nutrients from our food when everything is so inflamed.  Supplementing with essential vitamins helps our absorption while healing.  Niacin B3, the kind that flushes (nicotinic acid -not the same as nicotine in cigarettes, don't worry!) REALLY helps with the dermatitis herpetiformis flares.  Niacin and Thiamine make digestive enzymes so you can digest fats.  Add in healthy Omega Three fats, olive oil, flaxseed oil, avocado oil, coconut oil.  Vitamin D helps lower inflammation and regulates the immune system.  Thiamine helps mast cells not to release histamine at the slightest provocation.  Benfotiamine, a form of Thiamine B1, has been shown to promote intestinal healing.  Pyridoxine B6, Riboflavin B2, Vitamin C and Vitamin A help heal the digestive tract as well as the skin.  Our outside skin is continuous with our digestive tract.  When my outside skin is having breakouts and hives, I know my insides are unhappy, too.   Talk to your doctor and nutritionist about supplementing.  Blood tests are NOT accurate measurements of B vitamin deficiencies.  These tests measure what's in the bloodstream, not what is inside cells where vitamins are used.  Supplementing with essential vitamins and minerals made a big difference with me.  (My blog has more of my bumpy journey.) Let me know if you have more questions.  You can get through this!
