Just nitpicking - I would better suggest to use

blkid -p <device>

It will also detect crypto but also it will print if
there is some other signature.

You should see something like

# blkid -p /dev/sda2
/dev/sda2: UUID="..." VERSION="1" TYPE="crypto_LUKS" USAGE="crypto" ...

(-p means bypass cache, for old blkid just remove this switch
if not supported)
