– When doing blood tests for drugs why does the blood have to be taken from a vain or artery? 746 viewsJanuary 3, 2024 Question90.94K May 18, 2020 0 Comments I was watching a Police show and they couldnt prosecute a drug driver because they couldnt get a blood sample from him because of his drug use. Why (and this sounds really sadistic) can’t they take blood extracted another way?

Could period blood from a menstrual cup be used for blood testing? You are viewing 1 out of 4 answers, click here to view all answers. Register or Login
