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.
Phlebotomy is the act of drawing blood from a patient through the use of medical needles. The blood extracted through the needle is then studied by a physician in order to determine the patient's health condition. The blood may also be used in other patients in the form of a blood transfusion.
