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.
Phlebotomists typically do the following: Draw blood from patients and blood donors. Talk with patients and donors to help them feel less nervous about having their blood drawn. Verify a patientâs or donorâs identity to ensure proper labeling of the blood. Label the drawn blood for testing or processing.
