What does a laboratory scientist do?

A laboratory scientist (MLS), also known as a technologist or clinical laboratory scientist, works to analyze a variety of biological specimens. They are responsible for performing scientific testing on samples and reporting results to physicians.

laboratory scientists perform complex tests on patient samples using sophisticated equipment like microscopes. The data they find plays an important role in identifying and treating cancer, heart disease, diabetes, and other conditions. It is estimated 60 to 70 percent of all decisions regarding a patient's diagnosis, treatment, hospital admission, and discharge are based on the results of the tests laboratory scientists perform.

Scope of practice

laboratory scientists collaborate very closely with physicians and laboratory technicians in diagnosing and monitoring disease processes, as well as monitoring the effectiveness of therapy. Areas of laboratory training include microbiology, chemistry, hematology, immunology, transfusion medicine, toxicology, and molecular diagnostics.

laboratory scientists have a wide variety of responsibilities and duties, including:

• Examining and analyzing blood, body fluids, tissues, and cells
• Relaying test results to physicians
• Utilizing microscopes, cell counters, and other high-precision lab equipment
• Cross-matching blood for transfusion
• Monitoring patient outcomes
• Performing differential cell counts looking for abnormal cells to aid in the diagnosis of anemia and leukemia
• Establishing quality assurance programs to monitor and ensure the accuracy of test results
• Overseeing the work of a laboratory technician
