Immunology technologists examine elements of the human immune system and its response to foreign bodies. Blood bank technologists, or immunohematology technologists, collect, type, and prepare blood and its components for transfusions. Microbiology technologists examine and identify bacteria and other microorganisms.

Clinical chemistry technologists, for example, prepare specimens and analyze the chemical and hormonal contents of body fluids. Technologists in small laboratories perform many types of tests, whereas those in large laboratories generally specialize. Some technologists supervise clinical laboratory technicians. They also type and cross match blood samples for transfusions.Ĭlinical laboratory technologists evaluate test results, develop and modify procedures, and establish and monitor programs, to ensure the accuracy of tests. Technologists analyze samples for chemical content or a chemical reaction and determine concentrations of compounds such as blood glucose and cholesterol levels. They make cultures of body fluid and tissue samples, to determine the presence of bacteria, fungi, parasites, or other microorganisms. Technologists microscopically examine blood and other body fluids. Clinical laboratory technologists usually do more complex tasks than clinical laboratory technicians do.Ĭlinical laboratory technologists perform complex chemical, biological, hematological, immunologic, microscopic, and bacteriological tests. The complexity of tests performed, the level of judgment needed, and the amount of responsibility workers assume depend largely on the amount of education and experience they have. With increasing automation and the use of computer technology, the work of technologists and technicians has become less hands-on and more analytical. After testing and examining a specimen, they analyze the results and relay them to physicians. They also use automated equipment and computerized instruments capable of performing a number of tests simultaneously. They use microscopes, cell counters, and other sophisticated laboratory equipment. Technologists also prepare specimens for examination, count cells, and look for abnormal cells in blood and body fluids. They look for bacteria, parasites, and other microorganisms analyze the chemical content of fluids match blood for transfusions and test for drug levels in the blood that show how a patient is responding to treatment. Clinical laboratory personnel examine and analyze body fluids, and cells.
