Carer registration status
If the Patient's Registration Status is 'Patient Registered - Carer Needs Verification' you should check that the carer is correct for the patient.
You can see the carer's details by hovering over the 
button alongside their name
Once you have verified that the carer is correct for the patient...
You should update the registration status to 'Patient Registered and Carer Correct' and 'Save registration status'.
This will then unlock the request.
