You don't need to write a temporary file. You can pipe this directly into the while loop:
while read
do
...
done < <(ps -ef | grep ${1} | grep -v "grep ${1}" | grep -v pstop)
Also to avoid the second grep in Bash at least:
grep "[${1:0:1}]${1:1}"
$ ps -ef | grep '[l]vmetad'
root 965 1 0 Jan31 ? 00:00:00 /sbin/lvmetad -f
