Laboratory Technician

Career Overview

Laboratory technicians work in research facilities, hospitals, crime laboratories, and in private labs to analyze material samples and record data. Laboratory technicians typically work alongside scientists and laboratory technologists to set up and experiments, as well as interpret the results. Those who work in clinical laboratories collect and study blood and tissue samples from patients, while those who work in scientific research laboratories frequently perform tests on chemical or biological substances. Laboratory technicians in forensic crime labs analyze evidence from a crime scene to help solve cases.

Laboratory technicians also compose very detailed reports about their findings and communicate their results to the appropriate authorities, such as doctors, police detectives, or scientists.


Laboratory technicians are responsible for performing extremely careful observations and recording exact details of their procedures and results. In research laboratories they are responsible for setting up equipment, monitoring experimental procedures, cleaning up after experiments, and keeping labs well stocked. They must be comfortable handling potentially dangerous chemicals and other hazardous substances.

Clinical laboratory technicians are responsible for detecting the presence of abnormalities in a sample and passing on their findings to physicians, who can prescribe an appropriate treatment. They must be comfortable operating high tech instruments such as cell counters and microscopes. In addition, all laboratory technicians must be computer proficient, as they typically dedicate significant amounts of time to data entry, creating graphs, and analyzing mathematical and statistical results from experiments.

Educational Requirements

There are three academic paths to becoming a laboratory technician: a Bachelor of Science degree in Clinical Laboratory Sciences>, an Associate degree in science or medical technology, and a high school diploma coupled with formal laboratory training. In addition, clinical laboratory technicians must complete a certification program offered by the National Accrediting Agency for Clinical Laboratory Sciences.

The differences between these three educational paths are as follows:

  • Bachelor of Science programs are offered by colleges and universities and usually take about four years to complete. Bachelor degrees are required for some laboratory positions, such as biological and nuclear technicians.
  • Associate degree programs are offered by community colleges, junior colleges, and several accredited online schools. Associate degree programs typically take one to two years to complete.
  • A high school diploma or GED is sufficient for employment as a laboratory technician assistant, though about two years of on the job training are required to advance to the position of laboratory technician.

Areas of Specialization

Laboratory technicians can specialize in three different areas, though many combine specialties. For example, a forensic science technician may use tools and techniques of clinical laboratory technicians when analyzing evidence. The three means of specialization are:

  • By general discipline, as technicians typically choose to work either in clinical labs or science labs.
  • By work setting, as technicians might work in research facilities, hospitals, or crime labs, among other settings.
  • By working with one or more specific materials or substances, as do DNA analysts and plant scientists.

Below are general job categories for laboratory technicians:

  • Biological technicians, who examine plant and animal tissue, study animal behavior, and conduct lab tests.
  • Chemical technicians, who experiment with chemical solutions and analyze different compounds.
  • Environmental science technicians, who gather samples of air, water, and soil and test them for traces of contaminants.
  • Forensic science technicians, who analyze and interpret material evidence from crime scenes.
  • Medical laboratory technicians, who work in hospitals or research labs to determine the presence of disease or bacteria in a human sample.
  • Phlebotomists, who specialize in the collection, analysis, and interpretation of blood samples.
