Understanding the 6-week figure
NHS England counts everyone on the waiting list for a test at the end of each month and how many weeks they have waited since referral. The standard is that fewer than 1% of patients wait 6 weeks or more. Urgent referrals, including suspected cancer, are usually prioritised, so routine waits can be longer than the average suggests. If your wait is much longer than you were told, contact the hospital’s booking team or the Patient Advice and Liaison Service (PALS).
