When you receive drugs via a needle you are getting an injection but when a sample of blood is being removed, via a needle, it cannot be an injection as nothing is injected.
I am wondering if there is a word for the inverse of an injection in that something is removed rather than added.
So rather than "the nurse gave me an injection" we normally say "the nurse took a blood sample" but I am looking for alternatives.

'Extraction' might be a good fit for a direct opposite of injection, though it's most commonly used to refer to tooth removal. From https://www.merriam-webster.com/dictionary/extraction:
1: the act or process of extracting something
And,
3: something extracted
On the other hand, perhaps 'draw' is the word you seek. I would use it before I'd use extraction; though a cursory dig yielded no formal support for the use of 'draw' as a noun in this specific way.
The nurse gave an injection.
The nurse took a draw.
