Phlebotomists typically work in hospitals, medical offices, clinics, diagnostic laboratories, and blood donation centers. Though other medical personnel, such as nurses or medical assistants, might draw blood, phlebotomists specialize in doing so.
Concentrations
Phlebotomists don’t treat patients, but they do work closely with them. Depending on where they work, phlebotomists may see a specific age group more than any other. But they’re trained to draw blood from babies, children, adults, and elderly patients on a daily basis.
Phlebotomists need to understand the purpose of the blood draw so that they take the correct amount of blood. For instance, blood donors usually contribute a unit of blood (500 milliliters, or a little more than a pint) in a session. The volume of blood needed for laboratory analysis varies widely with the type of test being conducted.
Typically, one or several small (5 milliliter to 10 milliliter) tubes are drawn. Therapeutic phlebotomy, in which phlebotomy is used as a therapy for a condition like hereditary hemochromatosis (iron overload), removes a larger amount of blood than blood donation and blood analysis require—typically a unit of blood once a week.
Training and Credentials
A high school diploma, or its equivalent, a GED, is a basic prerequisite required for admission to an approved phlebotomy training program. However, many people hold an associate’s degree in the field or have completed phlebotomy training as part of a bachelor’s degree program in a health-related field, such as nursing.
Phlebotomy programs prepare students for employment quickly, from as little as eight weeks to less than a year depending upon the school type and program in which students enroll. The training program includes courses in anatomy, blood collection procedures, proper storage and handling of blood samples, and safety precautions.
After completing the phlebotomy training program, most people go on to become certified. There are no federal requirements for licensure or certification. The rules for phlebotomy are set by each state. However, most employers will hire only phlebotomists who have successfully passed the certification exam.
There are a number of certifying bodies, including the National Phlebotomy Association, the American Society of Phlebotomy Technicians (ASPT), and American Medical Technologists (AMT). Each organization has its own specific certification requirements, but each requires phlebotomists to have performed a certain number of “sticks.”
For instance, the ASPT requires at least 75 documented successful venipunctures and five documented skin punctures. AMT requires that applicants have completed a minimum of 50 successful venipunctures and 10 successful capillary punctures from human sources.
After becoming certified, continuing education is required to maintain the certification.
Appointment Tips
If you’re getting your blood drawn for medical reasons, you’ll probably have it done directly following an office visit. But because lab hours can vary, if you know you’ll need a blood draw, check ahead of time to be sure the phlebotomist will be available.
Some blood tests—including glucose tests that check blood-sugar levels and tests that determine your cholesterol levels—require you to fast beforehand, so you may be instructed not to eat or drink anything except water for eight to 12 hours before your appointment. If you think fasting might be a problem, schedule your appointment for early in the morning and bring a snack for after the appointment.
If you’re nervous about having your blood drawn, tell your phlebotomist. Whether you don’t like needles or don’t want to see blood leave your body, these experts are trained to put patients at ease. They know lots of tips for making your blood draw easier, including looking away or talking to someone to distract yourself.
If your veins are small or hard to access, the phlebotomist can use a smaller needle. Keep in mind that drawing blood usually takes less than three minutes, so the process will be over quickly.
If you’ve fainted in the past when donating blood or having your blood drawn, be sure to inform the phlebotomist. In these cases, positioning is key. You shouldn’t sit on top of the exam table; rather, you should be positioned in a low chair where falling is unlikely.
