In general black coffee is safe before any procedure,
unless total fluid input is a part of what they're testing.
It's really just water as far as your body is concerned ... unless you're exceptional sensitive to caffeine (I did run across one poor soul who had convulsions after only 4 cups .... but that's rare.)

"Black" coffee is coffee without milk and sugar.
Do not drink it just in case

Yes. Black coffee is a homogeneous mixture.
Heat can easily penetrate single items. When cream is added to coffee then there is more matter to penetrate before the coffee is cooled.
You should check with your doctor, but it should be ok to have black coffee with no sugar, cream or milk.
I work in a lab and we always tell our patients that they can drink black coffee with no sugar and no cream. So yes you may have plain, black coffee. The cream and sugar from the coffee would falsely elevate your cholesterol.
