What's Inside

Medical laboratory technicians (MLT), also known as clinical laboratory technicians, are the backbone of today's medical system, as almost all diagnosis is based on an analysis of biochemistry. As such, the demand for individuals skilled in medical laboratory science in the United States is high. According to the Bureau of Labor Statistics, the number of jobs in this field is 335,500, and this job number is expected to grow by 11% between 2020 and 2030.

What is a Medical Lab Technician?

Certified laboratory technicians, also known as lab techs, support doctors and other health care staff in diagnosing and healing diseases. They often work under the  supervision of a medical technologist. Some of their responsibilities include: 

  • Collecting body fluids, tissues, and other biological materials
  • Analyzing lab test results
  • Working with and maintaining medical laboratory equipment
  • Preparing slides and tissue samples for computer testing

The position requires an understanding of biochemistry, math, and medical laboratory technology and often requires passing a certification program or completing an associate’s degree program.

Clinical Laboratory Science Specialties

The duties of a lab technician may vary depending if the position is in a  hospital or private medical laboratory.

Areas of specialty in clinical laboratory science include chemistry, hematology, immunology, and microbiology.

  • A medical assistant to a chemist analyzes nutrition, hormones, or the presence of drugs and pathogens in blood or tissue samples.
  • A lab assistant to a hematologist conducts tests on blood cells to detect blood diseases such as HIV, anemia, or leukemia.
  • A lab tech to an immunohematologist runs tests to try and match one blood type to another or detect abnormal antibodies or allergens.
  • A lab assistant to a microbiologist detects the presence of microscopic organisms such as bacteria, algae, and fungi.

Keep in mind that a clinical laboratory technician might be practicing one or more of these specialties while on the job, depending on the size of the medical clinic, and whether or not it is situated inside a hospital.
