The short answer
A small study found changes in several research blood markers during the first year after a child’s celiac diagnosis. It did not establish a new clinical test. Follow up still looks at the child’s growth, symptoms, diet and appropriate bloodwork together.
Current explainer | November 8, 2026. A child starts eating gluten free after a celiac diagnosis. At the next appointment, the family wants to know: Is this working? A blood result can be one useful clue, but different blood tests answer different questions. And a change in a research marker does not, by itself, show that the lining of an individual child’s small intestine has healed.
A study in the November 2026 issue of Clinical Nutrition offers a look at the clues researchers are exploring. The study first appeared online September 25. The November issue gives families a reason to revisit it, especially if a follow up visit is coming up.
What the study followed
Researchers enrolled 41 children newly diagnosed with celiac disease across six hospitals in Spain’s Basque Country. Thirty four completed the study. The team collected samples around diagnosis and again at three and twelve months after the children began a gluten free diet. They looked at inflammatory proteins and microRNAs, small molecules involved in regulating how genes are used, alongside other markers and food records.
By twelve months, some inflammatory proteins had fallen and six measured microRNAs had changed. Two other markers, FABP2 and citrulline, showed no statistically significant change. The authors’ abstract says some markers “may be useful to monitor pediatric CD.” The word may matters.
A promising signal is different from a test you can use today
This was a small group followed over time. It can show patterns in that group, but it does not establish a cutoff that tells a clinician whether a particular child has healed. The abstract does not report how accurately the markers identify healing confirmed by a follow up biopsy. The study also does not test any prepared meal or show that eating gluten free benefits children who do not have celiac disease.
Standard celiac antibody tests are a different tool. The 2022 ESPGHAN pediatric follow up position paper describes using the appropriate antibody test alongside symptoms, growth and a diet review. Its guidance does not call for routine repeat biopsies in children doing well on a gluten free diet. Decisions about further tests depend on the child’s situation and belong with the care team.
What to bring to the next visit
- One practical snag. Bring a specific example, such as a school meal whose ingredients you cannot confirm or a practice night when the usual plan falls apart.
- One change you have noticed. Note when symptoms improved, returned or stayed the same. Ask how that fits with your child’s growth and other results.
- One question about the next result. Try: “What can this test tell us, and what would make you look further?” Ask which signs should prompt a call before the next visit.
If your child has not yet been evaluated, the starting question is different. See our guide to celiac signs and testing in children and talk with your child’s clinician before changing their diet for testing.
