Step-by-step explanation:
The main responsibility of a phlebotomist is to draw blood from patients for medical testing purposes. Phlebotomists are trained professionals who perform various procedures depending on the amount of blood needed. They may perform a venipuncture to draw blood from a vein in the arm, a capillary stick to collect a small amount of blood from the finger, earlobe, or infant's heel, or an arterial stick to collect blood from an artery.
Once the blood is collected, it may be analyzed by medical laboratories for various purposes such as diagnosing diseases, monitoring treatment response, or for transfusions and donations. Some phlebotomists may also work in blood banks and specialize in testing blood for diseases, blood types, and preparing blood donations.
