Understanding the tests scheduled for Surgery Day ( 24th May)

Thanks primek, I hope that happens to me but I have the test authorisation and it says blue dye, pretty hard to read the scrawl .  Either way I'm sure I'll cope it's the waiting that is hard ;)  especially with so many other family members in a bad way.  One was moved to palliative care on Monday and another in ICU, tip of the iceberg unfortunately. :/
