Another cold question re hospital outpatients appointment

I have a hospital appointment today in the haematolgy department and I have a stinking cold and a hacking cough, it wouldn't be wise to go to this appointment feeling like crap would it and spreading my lovely germs around. Plus I feel like a bag of poo and can't motivate myself to get out of bed. I think I have already answered my question. I'll call and rebook my appointment.
