Remove particular substrings

I have these strings:

"test 123"
"Test 123"
"Tes 234"
"T 123"
"abc 123"

I want to remove the strings "test", "Test", "TEST", "T". I want something like this:

"123"
"123"
"234"
"123"
"abc 123"

I tried this:

string.sub(/\s*[\w']+\s+/, "")

but it removes "abc". Please guide me on how to solve this.

I would do 

string.gsub(/t|test/i,"").strip

EDIT: if you want to remove "T", "Te", "Tes" or "Test", followed by a space, in any combination of upper/lower case, then do 

string.gsub(/te?s?t?\s/i,"").strip
