What's the Job Description of a Medical Lab Assistant?

Medical lab assistants analyze biological samples to determine the presence of diseases, disorders, and drugs. With the lab results, physicians can correctly diagnose and treat their patients.

Career Overview

Medical lab assistants, also called medical laboratory technicians, perform laboratory analyses in order to diagnose, prevent, or cure diseases. You'll work under the supervision of a medical laboratory technologist to run tests on blood, tissue, and other body fluid samples. You'll prepare the samples for computer testing and may perform any manual tests yourself. You'll make sure that specimens are correctly collected and labeled. You'll also ensure proper sterile techniques to prevent extraneous bacteria from damaging the tests.

Depending upon the size of the hospital or laboratory where you work, you may perform a wide range of tests or specialize in only one area. Areas of specialty include chemistry, hematology, immunology, immunohematology, and microbiology. In the area of chemistry, your tests may analyze the presence of drugs or biological chemicals in the blood. Your findings may confirm a doctor's diagnosis, or they may disclose an unsuspected condition such as pregnancy or high cholesterol. As a hematologist, you'll run analyses on blood samples. You may perform tests to determine diseases such as anemia or leukemia. You might even look for the presence of abnormal cells, as in sickle-cell anemia or cancer. If you work in immunohematology, you may run tests to discover abnormal antibodies or to match blood types.
