I had an MRI with contrast for my liver on July 3rd - this was due to an abnormality (allegedly common) called a hemangioma. I resquested a follow up a year later (this year) as I was not happy with them saying it's "possible" thaf it is a hemangioma.

I have an appointment on October 4th for my results and I have now been asked to book a blood test prior to receiving my results, is this normal? I am worried sick having to wait so long. 
 

Is this normal? I am going to be so cross if I turn up and it's nothing.
