I'd try using the link in the OP to investigate. I'm sure there is a point of enquiry
I think these parts stop me:
"You're currently taking antibiotics or you have just finished a course within the last seven days or have had any infection in that last two weeks."
"You have received blood or think you may have received blood during the course of any medical treatment or procedure anywhere in the world since 1st January 1980."
I've been taking an Anti-Biotic for the past 4 years or so for Acne (If not more)
And, I had a blood transfusion (I believe it was that?) as I lost a good couple of pints of blood a few years ago...
