Description
Celiac disease is a common immune-mediated disorder often overlooked due to vague or asymptomatic presentations. Current diagnosis depends on endoscopy and biopsy, which are invasive, costly, and frequently inaccessible, leading many patients to avoid or delay testing. To evaluate clinical evidence of new diagnostic methods including blood tests, genetic tests, biosensors, and AI tools, and assess whether these non-invasive techniques serve as alternatives to endoscopic biopsy in diagnosing celiac disease. Methods: A literature review was conducted using PubMed with keywords “Celiac Disease,” “Diagnosis,” “Biopsy,” “Non-invasive,” “Detection,” and “Methods,” yielding 343 articles published between 2021 and 2026. Of these, 152 abstracts were screened for relevance to non-invasive diagnostic approaches, with duplicate or unrelated studies excluded. Following screening, 82 articles were selected for full-text review, encompassing clinical, genetic, and computational studies examining blood-based diagnostics, antibody assays, electrochemical biosensors, genetic testing, and AI-assisted tools. Most studies indicate that high IgA-tTG levels can diagnose celiac disease with few false positives, though reliability may vary in patients with IgA deficiency, type 1 diabetes, or when different testing platforms are used. Novel approaches involving alternative biomarkers, mass-screening techniques, and AI-learning show promise in addressing such issues. Compared to traditional biopsies, these methods maintain high specificity, sensitivity, and diagnostic accuracy while being less invasive. Conclusions: Non-invasive tests like high IgA-tTG show high accuracy for celiac disease diagnosis and may reduce the need for invasive procedures while enabling early detection. However, biopsy remains essential in select cases. Future large-scale studies are needed to standardize and broaden reliable biopsy-free diagnostic.
