Bloodwork And Fasting?

I just got back from the doctors to discuss some GI issues I am having. I asked her about Celiac based on some other symptoms I am having. She doesn't think it's celiac but asked if I wanted to have a scope done.

In Canada the Celiac blood tests are not covered by our insurance. But she said she would start by sending me for some other blood tests that will measure inflammation.

I have to fast for an ultrasound she is sending me for and the lab told me to fast 8 hours for the bloodwork aswell.

Here are the tests she is sending me for:

Glucose

AST (SGOT)

Blood Film exam

Hemoglobin

WBC Count

ESR

CReactive (or CReactine) Protien (hard to read her writing!)

ALT

B-Carotene

Serum B12

I started thinking that maybe fasting isn't a good idea...any thoughts. I will double check with the lab again, but I just wanted some input first.

Fasting is usually associated with blood tests for lipids (cholesterol). But there is a glucose test on the list, and that can be either "random" or "fasting." In either case, it is diabetes that is being investigated.

A fasting blood glucose level more than 7.0 mmol/L (as measured in Canada) is generally considered diagnostic of diabetes if it happens on two occasions.

Creatine is a protein. The levels in the blood and urine are indicative of kidney function, and abnormal levels can be an indicator for diabetes.

Is it just plain hemoglobin? Glycosylated hemoglobin, also known as hemoglobin A1c, or HbA1c, is another diagnostic test for diabetes.

Thank you for the post Peter. So, do all of these tests look like it is investigating diabetes? Which test would be measuring inflammation as that is one of the things the doctor said she was looking for.

The doctor is investigating the possibility of diabetes, but this may only be to exclude it.

I don't recognize all the tests in the list. The one that do that is directly related to inflammation (or infection) is the WBC count. Inflammation is an immune response, and increased numbers of white blood cells are an indicator.

AST or SGOT is a liver function test, but can also indicate cardiac issues.

I don't know much about the others. B12 deficiency can be an indicator of so many things, including celiac disease, that the presence of that test does not signify anything notable. It is one of the tests that just gives a general health indication. If your B12 is okay, that rules out a lot of things. If not, keep looking for the reason.

      Draft gluten-free ciders… can they be trusted ?

      I'd go with a vodka tonic, but that's just me😉

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
