Questions About Blood Test

Rate this topic

Recommended Posts

Hello everyone. I'm new here, and I probably don't even have celiac disease but I have a few questions and I'm hoping someone can help.

I recently requested a blood test for celiac disease. I have a few relevant symptoms, and I have a close family member who has several symptoms as well. The test came back "normal" (I don't know the details, the receptionist told me this over the phone) but I am unable to let the whole idea go. I had removed most of the gluten from my diet two or three months before I had the test done, and I started eating it again five days beforehand. I know now from reading articles online that it wasn't long enough to make the result accurate. Also, when people say that steroid use skews the test, what exactly does that mean? I take a corticosteroid inhaler for my asthma, two puffs once a day. I have taken this medication daily for many years. Is that enough for the steroid to be in my bloodstream? If so, should my doctor have advised me to stop taking the inhaler before the test?

I'm not sure what to do now. I could continue to eat wheat, stop taking my inhaler and then have the test redone (assuming my doctor will give me another requisition) or I could continue to experiment with a gluten-free diet on my own and assume I am "gluten sensitive" in a way that can't be measured by the test.

Has anyone here had the blood test redone after preparing for it properly and had different results?

It is possible that your period of being gluten-free could have caused a false negative in your results. Some people's blood work goes back to normal fairly quickly whereas in others in can take years. Also, many doctors will just run a tTG IgA and the total serum IgA control test, that tTG test has a sensitivity of 75-95% which means it can miss 5-25% of all celiacs. See page 12 of this report (a good read): http://www.worldgastroenterology.org/assets/export/userfiles/2012_Celiac%20Disease_long_FINAL.pdf  You might want to make sure you had more than just one test run.

 

You would have to resume eating a couple of helpings of gluten per day for about 2 months to get an accurate test; requirements for a gluten challenge range from 1-4 slices of bread per day for 1-3 months.

 

I don't know how steroids will affect the test. Perhaps the lab could tell you?

 

I can't answer you question. Hopefully someone else has had your experience.  Best wishes.

Would taking steroids cause the blood tests to be inaccurate?

Yes, but only if you have been taking steroids for a prolonged period of time.

Thank you! I have been taking the medication for years, for my asthma. They say that inhaled steroids only go to your lungs but that can't be true because long term use causes side effects in other parts of your body (eyes, bones etc.)  So it must be in the bloodstream. I'll ask the lab about it. Thanks!

Guest myjade_84

I am also planning to undergo blood test for Celiac. But i have this fear that the test might not be reliable. But still i will do it and i won't change my diet yet. Maybe you should go back also on eating bread and then try the test again to be sure.

    • Here is a partial list of what I no longer suffer from as a result of not eating wheat. Some like the sleep apnea and gerd and back pain and addiction to alcohol were almost immediate. The foot pain is improved to just numbness sometimes. My long term depression went away when I added vitamin D 10,000 iu a day for a year, but the improvement started almost immediately. Muscle tone and energy improved when I added iodine. one sheet sushi seaweed a day. My Fibromyalgia is controlled with 15 mg oral Prednisone a day. I remember as a kid waking up and having to pick the dried mucuos off the roof of my mouth. That is gone and for the first time in my life I am a nose breather. Drink lots of water to help with the mucous if it is thick. Some mornings mine is like rubber cement. I need to quit smoking now.  You can improve have faith, but healing takes time. Stay the course. A Romaine lettuce salad everyday helped the gut pain. Gerd shortness of breath sleep apnea back pain snoring prostrate hypertrophy contact lens protein buildup night vision improved cataracts reduced head hair growth foot pain sleeping no more than 2 hours at a stretch slow healing no energy. Pretty much bed ridden. 
    • Celiac Disease is damage to the nooks and crannies in our intestines leading to malnutrition, vitamin deficiencies with all the various symptoms that make it so hard to diagnose. Then you add years of the antacids, antibiotics, Tylenol, opioids, alcohol, etc., each with their own particular side effects and damage. Now you've got a toxic environment that kills off the beneficial bacteria increasing malnutrition. Theoretically you can eat anything except gluten. But wheat is so ubiquitous in our diet and economy there are unlimited opportunities for cross contamination. So read the label. Use common sense. If there isn't a label it doesn't have wheat so you can eat. Big Food likes to add wheat to everything because it is addictive and helps them ensure you can't eat just one. Why on earth else would Campbells Tomato Soup have wheat listed as an ingredient? Meantime your body is in distress from malnutrition so you need to be sure to replenish D3, and Iodine for starters and treat and support any other symptoms while you heal. Good nutrition without wheat is the only way to stop progression. And just like chewing paint chips made with lead is bad, so is food with wheat.   well said, doesn't need a label.
    • We use pure cherry juice with our snow cone machine. Makes for a nice dessert after dinner.
    • Hi Kurasz, How's it going?  Any change for the amazingly better?  Or slightly better?  
      If not, hang in there, and keep praying! :)
    • Garden of Life brand Dr. Formulated Organic Fiber. It's certified gluten free. Also free of psyllium husk, dairy and soy. Also found that just simply increasing fiber intake works wonders. Perhaps try skipping a protein for at least one meal and fill up on veggies and fruits.
