Ok, in that case, something along the lines of

lsblk -o KNAME,UUID,PTUUID,PARTLABEL,PTTYPE,LABEL | grep <whatever>

might be a decent way. Checking return code, of course.

Although I'd personally prefer using proper udev rules and a predictable 
mount point plus a file system identifier, but that would require 
preparation outside your script.
