Making sure you are not getting any gluten

Melinda Dennis MS, RDN, LDN

Q: My wife has celiac disease. How can she check to make sure she's not getting any gluten? Should she do a blood test? She hasn't had one in about 5 years. Also, how often should she be seeing her gastroenterologist?


Answer: There are several ways to monitor how well a person with celiac disease is following the gluten-free diet and maintaining his/her health:

  1. The National Institutes of Health’s Consensus Development Conference on Celiac Disease. recommends that after the initial diagnosis and treatment, patients should periodically visit their physician and registered dietitian (RDN) skilled in celiac disease who will assess symptoms, adherence to the gluten-free diet, and any potential complications.1 See the NCA website for a list of RDNs who offer counseling on the gluten-free diet. Children should be monitored for proper growth and development. Health care providers can encourage their patients to closely follow the gluten-free diet for life. 1

Every year, see a gastroenterologist or other physician who is knowledgeable about celiac disease. The doctor will make sure you are getting the proper tests to ensure optimal health.2,3

Here are the general guidelines for seeing celiac specialists at BIDMC Celiac Center.

Shortly after diagnosis - both gastroenterologist (MD) and registered dietitian (RDN)

At 3 months - RDN

At 6 months - both MD and RDN

Annually (or every two years when well-established) - both MD and RDN

  1. Learn everything you can about the FDA and USDA labeling laws as well as obvious and frequently overlooked sources of gluten. Read labels carefully.
  2. Use valuable resources like and membership in a celiac support group to stay abreast of product information, advocacy, research, conferences and news as they become available.
  3. Check your celiac serology (blood work) each year. “The amount of celiac antibodies [TTG IgA, IgA EMA, DGP IgA or DGP IgG] in the blood should decrease with a gluten-free diet. Checking one of these antibodies annually shows doctors that the gluten-free diet is working and that you are not accidentally consuming gluten. While minor gluten ingestion will not show up in these tests, they do offer a good picture of general gluten exposure.”4 [At Beth Israel Deaconess Medical Center’s Celiac Center, we check celiac serology every few months until it is normal, and then yearly.]
  4. Request blood tests to check your vitamin and mineral levels. Vitamin and minerals, such as vitamin D and iron, can be low in people with celiac disease because damaged villi make it difficult to absorb nutrients. Low levels can be corrected with gluten free- supplements or occasionally injections.2
  5. People with celiac disease may have decreased bone density due to lack of absorption of vitamin D or calcium. Many clinicians recommend a bone density scan (DEXA or DXA scan) to assess bone strength and potential risk for osteoporosis and bone fractures in patients with celiac disease. Ask your doctor when he/she recommends a DEXA scan; timing varies among clinicians.3
  6. An upper endoscopy with intestinal biopsies is recommended to monitor patients who are not responding clinically or who have a relapse of symptoms despite carefully following the gluten-free diet.3
