Clinical Laboratory Scientists (CLS), also known as medical technologists (MT), analyze body fluids, tissues and human blood. Monitor the result of thousands of medical laboratory analysis, which are performed manually or using the most modern and complex biomedical instruments. They are responsible for the accuracy of test results and inform doctors about them. The CLS solve problems and use independent judgment in their work, which involves showing the relationship between results of different tests and interpret results. Physicians depend on these professionals to diagnose a valid and reliable, and determine the presence, extent and possible cause of disease.
