Test icles

this Covid test,
Now the horse has bolted..
I shall be required
to take for my employment..
I am rather a doubting Thomas
of tests,
They can give false positives..
then we've lost the contest,
before we started..
So many people off work..
with promises..
So many in dire consequence,
are the stats right they reported..
Guess I will open my mouth..
and be stabbed from North to South..
and wonder if my names on a list,
Not to be missed..
Or am I just a conspiracy theorist
