Patient message (English, deterministic template)

Your bowel screening test (FIT) found a small amount of blood in the sample. This is a screening result, not a diagnosis: most people with this result do not have cancer, but a colonoscopy is needed to find the cause. Next step: please reply to confirm you have read this message. Responsible team: your family doctor. Reply 1 if you understood, 2 to ask for a call from the care team, 3 for another language.

Patient message (Arabic, urgent case; pending native review)

أظهر فحص الكشف المبكر للأمعاء (فحص الدم الخفي في البراز) وجود كمية صغيرة من الدم في العينة. هذه نتيجة فحص كشف مبكر وليست تشخيصاً: معظم من تظهر لديهم هذه النتيجة لا يعانون من السرطان، لكن تنظير القولون ضروري لمعرفة السبب. الخطوة التالية: سيتواصل معك فريق الرعاية خلال أيام قليلة لشرح النتيجة. الفريق المسؤول: برنامج الكشف المبكر. أرسل 1 إذا فهمت الرسالة، أو 2 لتطلب اتصالاً من فريق الرعاية، أو 3 للتواصل بلغة أخرى. يرجى الاتصال بعيادتك اليوم. إذا شعرت بتوعك شديد، اتصل بالإسعاف (998).
