Medical Laboratory Scientist - Job Duties

Job Duties

Medical Laboratory Scientists work in all areas of the clinical laboratory including blood banking, chemistry, hematology, immunology, histology and microbiology. They perform a full range of laboratory tests – from simple prenatal blood tests, to more complex tests to uncover diseases such as HIV/AIDS, diabetes, and cancer. They are also responsible for confirming the accuracy of test results, and reporting laboratory findings to pathologists and other physicians. The information that a Medical Laboratory Scientist gives to the doctor influences the medical treatment a patient will receive. Medical Laboratory Scientists operate complex electronic equipment, computers, and precision instruments costing millions of dollars.

A Medical Laboratory Scientist analyzes human fluid samples using techniques available to the clinical laboratory, such as manual white blood cell differentials, bone marrow counts, analysis via microscopy, and advanced analytical equipment. Medical Laboratory Scientists assist doctors and nurses in choosing the correct lab tests and ensure proper collection methods. Medical Laboratory Scientists then receive the patient specimens, analyze the specimens, interpret and report results. A Pathologist may confirm a diagnostic result, but often the Medical Laboratory Scientist is responsible for interpreting and communicating critical patient results to the physician.

Medical Laboratory Scientists must recognize anomalies in their test results and know how to correct problems with the instrumentation. They monitor, screen, and troubleshoot analyzers featuring the latest technology available on the market. The MLS performs equipment validations, calibrations, quality controls, "STAT" or run-by-run assessment, statistical control of observed data, and recording normal operations. To maintain the integrity of the laboratory process, the medical laboratory scientist recognizes factors that could introduce error and rejects contaminated or sub-standard specimens, as well as investigates discrepant results.

Common tests performed by Medical Laboratory Scientists are complete blood count (CBC), comprehensive metabolic panel (CMP), electrolyte panel, liver function tests (LFT), renal function tests (RFT), thyroid function test (TFT), urinalysis, coagulation profile, lipid profile, blood type, semen analysis (for fertility and post-vasectomy studies), serological studies and routine cultures. In some facilities that have few phlebotomists, or none at all, (such as in rural areas) Medical Laboratory Scientists may perform phlebotomy on patients, as this skill is part of the clinical training.
