The doctor decided I needed a blood test so she sent details to the GP reception. I pick up the form, on which the receptionist has written a phone number. So this morning I phoned the number, where an automated system asked for my phone number to send me a link to the online booking system. They send me a SMS message with the link and I book an appointment online.
I mention this because the phlebotomy clinic is 2 floors up from the reception where I picked the form up from. I can't help thinking it might have been easier to use the building's infrastructure, i.e. the stairs rather than handwriting the phone number, making a phone call, getting a message, and using the link to make the appointment.
