As a laboratory technician, you will examine bodily fluids, tissues, and cells and make determinations about health conditions as well as the presences or absence of diseases. You will be trained to use technology and scientific equipment to analyze specimens. You may look for parasites, bacteria and other microorganisms or evaluate blood cells under a microscope. You will evaluate data and test results for accuracy and communicate results to the physicians. As a phlebotomist, you will draw blood from patients by performing venipuncture (drawing blood by using needles). Blood samples are used for testing (for diagnosis or experiments) or for blood transfusions.
