It might not be a career field you’re familiar with, but chances are high you’ve seen a phlebotomist* at some point in your life. They’re the people who draw blood and make sure it’s labeled correctly before it goes off to your doctor or the lab. Let’s dig deeper into what phlebotomy is all about and how this career field continues to grow!

What Do Phlebotomists Do?

The heart of what phlebotomists do is draw blood. This could be done for testing, transfusions, research or blood donations. It’s important phlebotomists understand the purpose for the blood draw so they take the correct amount and label it properly.

Where Do Phlebotomists Work?


Phlebotomists working in a hospital might be called to draw blood from a patient’s room, or they might work in the lab drawing blood from patients who come to them. Since phlebotomists spend their entire day drawing blood, you can be sure they’ll know the best way to find your vein and get what they need as quickly and painlessly as possible.

Medical and Diagnostic Labs

If you’ve ever had to go to a lab for a blood test, you’ve probably seen a phlebotomist. Before drawing your blood, your phlebotomist will match the laboratory requisition form to specimen tubes. They might also enter patient and specimen information into a database.

Blood Donor Centers

At blood donor centers, phlebotomists need to determine donor suitability from interview results, vital signs and medical history. They may also conduct hemoglobin tests to ensure donor iron levels are normal and calibrate machines used for things like plasma collection.

Doctors’ Offices

It might be hard to tell if you’re seeing a nurse, medical assistant or phlebotomist at your doctors’ office. Each role is responsible for drawing blood, but phlebotomists specialize in doing so. They might also transport specimens from your doctors’ office to the lab for testing.
