How Dr. Çeltik works with international patients

Dr. Çeltik consults in Turkish and English, and interpreters can be arranged for families who speak other languages. Before a visit, the international patient team coordinates the collection of the child’s prior reports and imaging, such as ultrasound, MRI or CT reports, laboratory and pathology results, endoscopy reports, operative notes and discharge summaries, and arranges appointments and the hospital visit. A first consultation typically covers the child’s history and symptoms, growth and feeding, a review of existing test results and previous treatments, a clinical examination and a discussion of the possible options. Video consultation is available for international patients who wish to discuss their child’s situation before travelling or as part of follow-up.
