Are Blood Tests The Only Way To Dx

I went to the doc with the tests that were suggested here. I was told that I should have a colonoscopy (I am 50 and they keep pushing that). Since my symptoms are mostly systemic (swelling, rash, constipation) I declined the colonoscopy. My doc was not familar with the testing and suggested I see an allergist.

 

If I go to the allergixt I am sure they will do the pin prick stuff...will that show a gluten intolerance? My other option was for a referral to a GI specialist...but I would have to wait a few months to get in to see the GI guy since I am not in serious distress.

 

Any advice? My other option is to have a lab order the tests and pay myself. Is there any lab out there that does these?

No, for celiac there is also the endoscopy where they do a biopsy and in addition to that there is a gene test, however, this one can't diagnosis by itself.

 

There are no 'official' tests for an intolerance, outside of a diet change to see if that is whats causing it.

 

As for labs, i don't know.

Why won't he order your blood work? The colonoscopy has nothing to do with Celiac but is still a good idea over 50. They could do the endoscopy ( for Celiac) at the same time. I know several people who have gone for the routine colonoscopy at 50 with no symptoms and found pre- cancerous polyps. If left, they would likely become cancer in a few years.

celiac is not an allergy and neither is non- Celiac gluten intolerance. At the current time, there is no test for NCGI.

Ditto the others.

 

The blood tests for celiac disease are:

tTG IgA and tTG IgG

DGP IgA and DGP IgG

EMA IgA

total serum IgA

AGA IgA and AGA IgG (older and less frequently used)

 

Make sure you are eating gluten in the weeks prior to testing.  Good luck.

 

Oops... editted to add that I saw you already knew the blood tests. Sorry.

I went to my doc to have my thyroid re-checked and I suggested the colonoscopy since I'm 51.  The gastro prior to the procedure recommended an endoscopy since I was anemic and had thyroiditis.  Blood test was positive and endoscopy showed moderate to severe damage.  My colonoscopy was normal.   :D Lucky for me, my gastro was Celiac savy (he must have just went to a conference!)  

 

An allergist can only test you for an allergy -- which is fine (I've got plenty of allergies to boot).  But I'd make the appointment for the gastro doc.  

 

I would have gone gluten-free right after the blood test, but 1) I needed the colonoscopy anyway and I'd be prepped for the endo and 2) a definite diagnosis would benefit my family.

      Hi Katht - I sympathize with your struggles in following a gluten-free diet and lifestyle. I found out that I had Celiac Disease a few months before I turned 70. I just turned 89 and it has taken me almost 20 years to attain a fairly normal intestinal function. I also lost a lot of weight, down to 100 lb. down from about 140 lb. What Trents wrote you was...

      Hi Colleen Are you supplementing B12/having injections? I have learned recently that sometimes when you start addressing a B12 deficiency, it can temporarily make your symptoms worse. But it is important not to stop the treatment. Regarding your problems with anxiety, again that is another symptom of a B12 deficiency. I didn't know...

      Hi Katht -  I sympathize with your struggles in following a gluten-free diet and lifestyle. I found out that I had Celiac Disease a few months before I turned 70. I just turned 89 and it has taken me almost 20 years to attain a fairly normal intestinal  function. I also lost a lot of weight, down to 100 lb. down from about 140 lb. What Trents wrote you was very true for me. I am still elimination foods from my diet. One person suggested you keep a food diary and that is a good idea but it is probably best just to do an elimination diet. There are several ne and maybe one for celiacs. I used one for a while and started with plain rice and zucchini and then added back other foods to see if I reacted or not. That helped a great deal but what I did not realise that it would only very small amounts of some foods to cause inflammation in my intestine. Within the last few years I have stopped eating any trace amounts of hot peppers, corn and soy(mostly in supplements) and nuts, (the corn in Tylenol was giving me stomach aches and the nuts were causing foot pains). Starting an elimination diet with white rice is better than brown rice that has some natural toxins. In addition it is very important to drink sufficient plain water. You can find out how much to drink for your height and weight online. I do have difficulty drinking 48 ounces of water but just recently have found an electrolyte supplement that helps me stay well hydrated, Adding the water and electrolytes may reduce muscle cramps and gag spams you wrote about. . Also buy some anti-gluten enzyme capsules to take with meals. I use GliadinX advertised here. These are a lot of things to do at one time as they reflect my 20 years of experience. I hope you do what you can manage to do over time. Good luck and take care.

      Hi Colleen Are you supplementing B12/having injections? I have learned recently that sometimes when you start addressing a B12 deficiency, it can temporarily make your symptoms worse.  But it is important not to stop the treatment.  Regarding your problems with anxiety, again that is another symptom of a B12 deficiency.   I didn't know what anxiety was until it hit me like a train several months before gastrointestinal issues began, so I can certainly relate.   Two books which helped me hugely were At Last A Life by Paul David (there is a website you can look up) and The Depression Cure: The Six-Step Programme to Beat Depression Without Drugs by Dr Steve Llardi.  Although his book is aimed at people who have depression, following the principals he sets out was so helpful in lessening my anxiety.  Llardi suggests we need to focus on getting enough: - physical exercise - omega-3 fatty acids - natural sunlight exposure - restorative sleep - social connectedness - meaningful, engaging activity   ... and we should feel a lot better. That is not to stay you must stop taking medication for depression or anxiety if you have been prescribed it, but adopting the changes Dr Llardi sets out in the book should really help. Can I just ask two more questions:  1) you say that you are B12 deficient, did they test your iron levels too?  If not, you really ought to be checked for deficiency and, 2) did they check your thyroid function, as an overactive thyroid can be cause rapid heartbeat and a lot of coeliacs have thyroid issues?
