Users of this website may know about this but I didn't until recently. If you have a form of vasculitis which affects the kidneys and has meant that you are treated by a hospital renal unit you may well be able to sign up to Renal Patientview. This means that with a username and password you can access your own records at the renal unit including all your blood test results and medication changes. Very useful if, like me, you like to keep a close eye on your blood results including kidney function etc. As I understand it, many renal units are part of the scheme although not all of them.
