What Does a Phlebotomist Do? Phlebotomy is used for many reasons in the medical field. A physician may need to test the blood of a patient or a patient may be donating blood to help another person. The physician is not the one to take the blood from the patient. The phlebotomist does this as part of their job role. The phlebotomist takes blood by entering the veins, usually through the middle arm or wrist.
