What Does a Phlebotomist Do?

Phlebotomy is the process of drawing blood from a patient  for clinical or medical testing, transfusions, donations, or research. Phlebotomists work in hospitals or medical labs and collect blood mainly via venipuncture. Fingersticks and other procedures are sometimes used as well. Phlebotomists are responsible for identifying and preparing the patient for the procedure as well as the proper labeling of the sample.

Phlebotomists are different from nurses and other medical professionals in the sense that they are hyper-specialized and focused on making the process of drawing blood as pain-free and comfortable as possible. Phlebotomists are responsible for drawing blood in a professional and compassionate manner, and in accordance with different medical practices.

Phlebotomists can draw blood for medical testing, transfusions, or donations. There are a few ways that phlebotomists draw blood. The most common is venipuncture, the actual puncturing of a vein with a needle. You have probably experienced this when giving blood or having tests.

Another common drawing technique is using fingersticks to draw multiple smaller samples. This method is often associated with testing for diabetes and testing on children. The final method of drawing blood that phlebotomists use is heelsticks. Heelsticks are similar to fingersticks, but are used on the heels, particularly with infants.

Overall, phlebotomists must familiarize themselves with all facets of drawing blood, and must be committed to doing so in the most pain-free and professional way possible.
