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.
Phlebotomist Duties. Before becoming a phlebotomist, itâs essential that you understand all of the duties that are involved in this occupation. Phlebotomy certification may not be for everyone, though some people may be attracted to this job by the relatively short certification time.ollection of Blood Samples. To collect a blood sample from a patient, a phlebotomist needs to first find a suitable vein to puncture with the needle. In most cases, a phlebotomist will choose to use the median cubital vein. This vein is located on the inner side of the forearm, just inside the fold of the elbow.
