That's actually a poor solution. Should the value being tested expand to multiple fields, it could lead to syntax errors or other forms of unexpected behavior.
You could quote the command substitution, to ensure that test/[ is only passed a single argument, but, if using grep anyway, I would drop the use of test/[ altogether, redirect the output of egrep to /dev/null (or use the -q option if available), and allow the if statement to use egrep's exit status directly.
