NICE Diagnostics Guidance DG56 provides evidence-based recommendations on the use of quantitative faecal immunochemical testing (FIT) to support referral decisions for suspected colorectal cancer in primary care.

This updated guidance replaces DG30 and refines criteria for urgent referrals, aiming to streamline the colorectal cancer pathway, reduce unnecessary procedures, and improve early detection. It outlines when FIT should be offered, how results should guide referral decisions, and emphasizes the importance of clinical judgment and safety netting in patient care.
