Which department?

So random question..

 

I saw the Gastro consultant last week.

hes asked me to take stool samples back to the hospital. At the time he said something vague like "take them to upstairs".

I've had a look on the hospital site map and can't figure out what department he's talking about.

anyone know what the department would be called?

I'm going to be wondering around the hospital with my samples trying to find someone who wants them :)
