Depending on the state where employment is granted, the job duties between MLSs and MLTs may or may not be similar. For example, in Florida, a MLT may only perform highly complex testing while under the direct supervision of a clinical laboratory technologist, a clinical laboratory supervisor, or a clinical laboratory director.

Quality control (QC) is a measure of precision, or how well the measurement system reproduces the same result over time and under varying operating conditions. Laboratory quality control material is usually run at the beginning of each shift, after an instrument is serviced, when reagent lots are changed, after equipment calibration, and ...
Years later in 1876, German chemist Oscar Döbner (Doebner) synthesized the first PCB in a laboratory. [94] Since then, large amounts of PCBs were released into the environment, to the extent that there are even measurable amounts of PCBs in feathers of birds currently held in museums before the production of PCBs peaked.
