While not su-ed (like in .profile), create a file, e.g., /tmp/try.
chmod 044 /tmp/try.  (Obviously, you need a more unique filename.)

Here's the test you asked for:

           if [ -r /tmp/try ]
           then
             echo I am su-ed
           else
             echo I am not su-ed
           fi
