The Lloyd clinic has a daily ticket allocation system. These are given out on a 'first come first served' basis 20 to 30 minutes before the first patient is seen. Tickets indicate the approximate time that you will be seen on the day and treatment offered if necessary. The Lloyd Clinic is an exceptionally busy department and limited tickets can be exhausted by mid day. Please attend early to avoid disappointment. Last possible walk-in registration is 50 minutes before the clinic closes that day.
