After rinsing to remove unbound antigen, another aliquot of the monoclonal antibody is added to the well. The antibodies in this aliquot are modified so that they carry what is known as a reporter enzyme. A reporter enzyme is designed to produce a color change when the enzyme reacts with its substrate.
Phlebotomists [edit]. Phlebotomists are people trained to draw blood from a patient for clinical or medical testing, transfusions, donations, or research. Phlebotomists collect blood primarily by performing venipunctures, (or, for collection of minute quantities of blood, fingersticks).hlebotomy (from the Greek words phlebo- , meaning pertaining to a blood vessel, and-tomy, meaning to make an incision) is the process of making an incision in a vein with a needle.
A phlebotomist is a healthcare professional who is trained to draw blood from a patient in a safe and sanitary manner. Phlebotomists may draw blood samples for tests or collect blood donations. Formal training and education, and often certification or licensure, are required in order to become a phlebotomist. Source: *U.S. Bureau of Labor Statistics.
