Ronna can also see patients for their contraceptive needs to include repeat contraceptive pill, change of contraceptive pill and those wishing to start oral contraception. When booking an appointment to see one of our nurses, you may be asked what the appointment is for. This is to ensure that we book you with the correct nurse for the service required and allocate sufficient time for you to be cared for.

Appointments are made at the request of a doctor and appointments for blood tests are held during morning surgery to enable the samples to reach the pathology department for testing.
