I had to have one several years ago (when I was healthy - prelyme)
It was a requirement at a new job.
I have a phobia of needles and it wasn't so bad.
The needle is put just under the skin - not into the vein.
They will check for a reaction several days later (can't remember how many days) - a reaction means you have been exposed to TB.
