Igg Testing Questions


Michelle1

Recommended Posts

Michelle1 Rookie

Hi there...I've been gluten free since my biopsy so about 10 months...still having random neckrash and hives on my eyelids and recently was tested for food allergies.  The IgE results were all negative but the IgG came back positive for casein, wheat, corn, beef, apples, banana's, potatoes and tomatoes.  It only tested 10 different things (ok for chicken and soy)...I've been trying to find information on this while waiting to see a nutritionist but my dr just said for now stay away from the highest offenders...the levels were supposed to be under 2.0 and corn was 11, bananas 9, beef 7.4, casein 5.5 etc..while tomatoes were 2.5 and potatoes were 2.0 which they marked as high...

I was told at my endoscopy 10 months ago that I had a lot of visual inflammation of the esophagus, stomach and intestines and the results were celiac disease gerd and inflammation of stomach....

Many places I read that if you had low positives to ignore those and I'm thinking no I should notice all positives....?? and I can't find any reference to what is considered "low positive"...is the 11 a low positive that I had for the corn or is it like a WHOA off the charts....I can't even find a reference for it...Any insight anyone???

Hi. Having high IGG for a particular food is not a definitive marker of intolerance/allergy. One can have have super high levels toward a food, and still tolerate it just fine. I think its best to look at the test results as a "hint" as to what might be triggering your symptoms. Personally, I would start by avoiding all the positive foods (if possible), and slowly reintroduce the foods one at a time, while carefully observing for negative reactions. I would also consider starting a Open Original Shared Link with your new foods, to prevent developing intolerance to them. Doing so has been very helpful in my experience.

 

The reason you are having a hard time finding concrete answers for whats considered high etc.., is because the science behind the method (IGG food allergies) is still lacking, hence the idea to look at it as a "hint".

Is this IgG test a blood test? If so, can any general family doctor run the test? Thanks in advance!

IgG isn't useful for food allergy testing. IgE is what is use for allergies and even that is only accurate 50% of the time for a positive result.  There aren't any reliable tests for an intolerance other than an elimination trial and reintroduction.

Yes, it is a blood test. However, the basis for using IGG levels as a means for diagnosing food-intolerance's has not been scientifically proven. So you average doctor may be uninterested in, or not familiar with the test.

 

I agree with StephanieL, in that the only reliable way to determine a food-intolerance is by eliminated the food for a few weeks, and then reintroducing it, and observing how you respond.

 

Here is a quote taken from Genova-Diagnostics, a leading provider of the IGG tests:

 

If you were on steroidal anti-inflammatory drugs or if you were not consuming a tested food, the test probably will not show a positive reaction. If you are already on an elimination diet due to known food reactions, a negative result on an IgG4 food antibody profile does not necessarily mean you can freely eat the food without experiencing symptoms. Reintroduce any previously reactive foods with caution.

 

 

It seems more likely IGG levels simply reflect the contents of your diet, not which foods you are intolerant to. Though, if one has a leaky gut, its quite likely they will have developed intolerance's to many of the foods they are currently eating. This is probably why some people find the test to be "effective".

If a certain food does not cause any symptoms, a positive IgG test alone should not be a reason to avoid that food. Presence of IgG antibodies means previous exposure to that food and not an allergy to it.

Thank you for the info!

      my ttg iga was 16.5 3 months ago and jumped to 30.1 last week. my iga was 415 and jumped to 455. This was done at a different lab though than the first test for ttg iga one had units as ml the other as cu... so not sure if they really jumped as much as shown. i am so strict on my diet and have no clue why this is happening  thank you for attaching this, could this happen randomly even after being gluten-free for so long ? my ttg iga was 16.5 3 months ago and jumped to 30.1 last week. my iga was 415 and jumped to 455.

      Hi all, I’ve been following a strict gluten-free diet for 1.5 years since I was diagnosed. The last few weeks though I’ve suffered almost continual bloated stomach and flatulence. It literally is almost constant - and I was never this way before. I can’t think of any change to my diet, activity, etc. I’m dying - it’s so uncomfortable and embarrassing to feel like I have zero control over this. Any ideas? Thank you!

      @Levi, How are you doing?  Sorry I missed your posts.   How's your thyroid?  Did your Vitamin D stabilize?  Do you have long hauler syndrome after Covid? Consider switching to Vitamin D 3, the natural form of Vitamin D.  Vitamin D 2 is the synthetic form of Vitamin D which the body can have difficulty changing to an active form.  Also, Thiamine is needed to active Vitamin D.   Hypothyroidism can be caused by Thiamine deficiency.  The thyroid is an organ that uses lots of thiamine.  sometimes thyroid deficiency can also cause hyperthyroidism, or swings between both hyper- and hypo-thyroidism. We need more Thiamine when we're sick with an infection (like Covid) or injured.  We need more Thiamine when we're physically active.  We need more Thiamine when we're emotionally stressed or worried.  Our brain uses the more Thiamine just thinking than our muscles do while running a marathon.  Thiamine is extremely important in fighting infections.  Covid patients and long haulers have found taking Thiamine has improved their survival rate and long term symptoms.   Consider taking a Thiamine supplement like Benfotiamine which has been scientifically shown to promote intestinal healing.  Damaged villi need thiamine to grow back.   Be sure to take a magnesium supplement, too.  Thiamine and magnesium make life sustaining enzymes together.  You also need magnesium to keep calcium in the bones.  The thyroid regulates calcium.  A wonky thyroid can lead to reduced bone density.   Remember the B vitamins all work together in concert so adding a B Complex to Benfotiamine and magnesium supplements and Vitamin C would be great in improving absorption of nutrients while we're dealing with celiac disease.

      I'm looking for bars or non perishable snacks for my 2 kids. They are 5 and 3. The 3 year old seems sensitive to oats also. We do a lot of long hikes and bike rides. They eat mostly fresh foods but for these rides and hikes we need easy and non perishable. Also that taste good! We do a lot of larabars and freeze dried apples but those are getting old. Any ideas?

      Oh, @MagsM, Sorry you had that happen with Niacin.  500mg is the maximum amount of Niacin one should take.  Niacin works hand in hand with Thiamine, so a big influx like that can imbalance thiamine if not supplemented at the same time.  All the B vitamins work together in concert.  Niacin in doses at 500 mg or above have been used by doctors to lower triglycerides levels and raise HDL, the good cholesterol.  Pharmaceuticals to do the same thing are more expensive and thus more profitable for physicians. Has your doctor tested you for H. Pylori?  An infection by H. Pylori can be tested for by your doctor.  H. Pylori can cause low tTg IgA results, too.   I would hold off on the microbiome test for now.  Your microbiome is going to change when you go gluten free.  Your microbiome will change when you start taking Thiamine.  Thiamine supplementation influences which microbes grow in the intestines, encouraging beneficial bacteria and getting rid of the bad ones.  Thiamine in the form Benfothiamine promotes intestinal healing, too.  Adopting the Autoimmune Protocol Diet (by Dr. Sarah Ballantyne, a Celiac herself) after diagnosis will also change your microbiome.  This is the best diet to heal and recover, IMO.   If you're going to have more testing done for vitamin deficiencies, don't take vitamin supplements beforehand, otherwise the tests will measure the vitamin supplements in your bloodstream and give false results.  Same thing will happen if you take B vitamin shots.  The supplements you mentioned (Arterosil HP and Vascanox HP) are herbal support and do not contain all eight B vitamins.  There's no harm in taking them, but I prefer a B Complex that contains all the B vitamins in activated forms like Life Extension's Bioactive Complete B Complex.  All the B vitamins work together in concert.  Magnesium is important to supplement as thiamine and magnesium make life sustaining enzymes together.  Do not buy supplements containing Thiamine Mononitrate because it is not biologically active.  It is very hard for the body to utilize.  Most of it (70%) passes out unused.    Yes, my Meniere's disease has not returned.  I was deficient in Vitamin D.  I took high doses of Vitamin D 3 to correct the deficiency quickly.  I also took TTFD (tetrahydrofurfuryl disulfide) which is a form of thiamine different from Benfotiamine.  TTFD can cross the blood brain barrier without a carrier, so it can get into the brain very easily.  TTFD helps the Vagus nerve function.  The Vagus nerve regulates the ears and balance, and also the digestive system.  I like Allithiamine by Ecological Formulas.  I also like Thiamax by Objective Nutrients.  You should have improvements within a hour with TTFD.  TTFD is much stronger, so lower doses will give amazing benefits (50-200 mg).   I hope this helps give you some direction to take on your journey!
