How long do blood antibodies last in a test vial?

I had bloodwork done by Quest Diagnostics on 3/16 in Michigan and they ended up shipping it out to California, then it got forwarded over to Virginia where after over a week they finally tested it today (3/24). I called and supposedly their testing is half-done and they have more of the panel to complete the next 2 days.

How long is my one little vial of blood viable for testing? Do the antibodies show accurately for a long period of time under proper storage or do they lose their detectability over time? I'm just afraid of inaccuracies or false negatives.

These are great questions, and I'm not sure about this, but believe that they would likely follow proper protocols for storing and shipping the samples. It would be great to get an answer about these questions from them directly, have you tried asking Quest Diagnostics?

I found this page from Quest.  It partly depends on the temperature at which your sample was stored and shipped.  Keeping samples cool while shipping requires ice packs, which is more weight, thus more expensive, so it was probably shipped at room temperature.

Look on the right, under Specimen Stability. Eight days is beyond their storage time frame for refrigerated samples.  

Specimen Handling for Celiac Comprehensive Panel

I would definitely contact Quest, and if they haven’t handled the sample per their own protocols, request a retest if you are at all suspicious of the results.

      I'm not saying this is what you have, but your description reminds me of Morgellons, which are not very well understood. Here is a review from a reputable source. If it seems similar to your experience, you could raise this question with your Dr. https://my.clevelandclinic.org/health/diseases/morgellons-disease

      Celiac flare years after diagnosis

      Hi Trent, no dairy. Other than good quality butter. I have been lactose free for years. No corn, sugar, even seasonings and spices. I don't eat out. I cook my own food.

      @nancydrewandtheceliacclue, are you consuming dairy? Not sure if dairy is part of the carnivore diet.

      Celiac flare years after diagnosis

      Hello Russ! Thank you so much for your reply. I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal...

      Celiac flare years after diagnosis

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting...

      Hello Russ! Thank you so much for your reply.  I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal allergy inflammation be contributing to my celiac inflammation? I am so careful, there is no way I could ingest gluten. For example, couple of months ago I tried a cough drop that says it was gluten free. I checked ingredients, it seemed fine. But just taking one of those caused me to have nausea, vomiting, and the same extreme abdominal pain. Have you ever heard of anyone else having symptoms like mine after being diagnosed celiac and strictly gluten free? The last episode I had like this was yesterday, after I ate a certified gluten-free coconut macaroon with a little chocolate on it. I have eaten coconut and chocolate before with no issue,  so I didn't see how I could all of a sudden have such a strong response.

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting. I don't think that touching or throwing bread around would lead to you ingesting enough to cause a reaction. There are case reports of farmers with coeliac disease reacting to the dust from gluten-containing animal feed but they were inhaling large amounts of dust over a long period of time in barns. Perhaps you episodes are caused by a reaction to something other than gluten? Have you had your antibody levels checked to see whether you are still being exposed to gluten?
