A studio manager got the shock of their life when they found a SLUG in a lateral flow test.
Sophs Forte, 28, picked up a box of Flowflex tests, which are available from the NHS, from their local pharmacy earlier this month.
But when they opened one up they got the shock of their life - finding a slimy creature inside.
Their reaction was to yell, "What the f***, there's a slug!" before launching the vial - and the entire box of tests - into the bin.
Sophs said: "I pulled one of the vials and immediately spotted something black - and I quickly realised what it was.
"I shouted to my family but nobody believed it until I showed them. It was just squashed in there - luckily it wasn't moving."
They said after the initial shock, the funny side kicked in.
"As disgusting as it is, I found it quite funny," Sophs continued.
"I have no idea how a slug would even have ended up in there - at what point in the production line would that happen?!
"Well... the slug was declining to answer.
"I'm not blaming the NHS, they've worked hard enough and have a lot on. I don't know what happened or how.
"But keep an eye on your Covid tests!"
Flowflex has been approached for comment.
