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.
While there is no degree requirement to become a phlebotomist, associate's and bachelor's degrees are available. Phlebotomists do blood work that is used in laboratory testing, blood transfusions and medical studies. They work at blood banks, hospitals, laboratories and neighborhood health centers. Although no education is mandatory to be employed as a phlebotomist, most 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.
