Physicians, nurses and other front-line clinicians are the most visible parts of the health care system, but there are hundreds of thousands of clinical and medical laboratory technicians working behind the scenes to provide those front-line workers with the information they need to make accurate diagnoses.

Clinical and medical lab technicians and technologists work in hospitals and diagnostic laboratories, running tests on samples collected by medical staff. There's a slight difference between the two types of lab tech — technologists are typically able to perform and oversee complex laboratory procedures, while technicians are responsible for simpler tests and usually work under the supervision of a technologist or lab manager.

Employment of lab technicians and technologists is on the rise, as well, according to the Bureau of Labor Statistics of the U.S. Department of Labor. Job opportunities in this field are projected to increase by 11 percent by 2028, a rate of growth that's much faster than the national average for the job market as a whole.

Read on to get more info about the career environment for clinical laboratory technologists and technicians, find out how a college degree program in the field typically unfolds and pick up some tips for boosting your career prospects after graduation.

A concentration in cytogenics supplements training in clinical lab science techniques with study of the relationship between disease, heredity and human chromosomes.

Career Outlook

More than 330,000 people work as clinical laboratory technicians and technologists, according to BLS data, and over 35,000 new positions are expected to be added to the workforce over the next several years. Employers tend to prefer candidates with four-year degrees in the field, but some entry-level technician jobs may be available before you officially finish your bachelor's.

Positions for laboratory managers are on the rise as well, although they typically list several years of experience in the field as one of the qualifications for employment. We go into some detail about clinical lab science jobs in the section below.

Clinical laboratory technician

What do clinical laboratory technicians do?

Working mainly in hospitals and off-site diagnostic testing centers, clinical laboratory technicians typically conduct simple analyses and ensure that equipment is in the proper shape for effective testing. Here's a short list of the type of duties that a clinical laboratory technician might perform on an ordinary workday:

How to become a clinical laboratory technician

The responsibilities of a clinical laboratory technician are typically less substantial than those of their more experienced counterparts, so it's far from impossible to find a job in the field before fully earning your bachelor's degree. The Occupational Information Network (O*NET) reports that 31 percent of clinical and medical laboratory technicians employed in 2020 held just an associate degree, and another 10 percent had a college diploma, certificate or other non-degree award.

Depending on the state where you live, a license may be required before you can officially work in a clinical laboratory. Contact your State Board of Health or Board of Occupational Licensing for more info.

Clinical laboratory technologist

What does a clinical laboratory technologist do?

Clinical laboratory technologists perform a similar set of on-the-job duties, albeit at a typically higher level of responsibility, to the technicians described above. They run complex analyses of blood, fluid or tissue and oversee the more elementary processes conducted by lab technicians.

Clinical and medical laboratory technologists may also specialize in a particular area of the field. Here's some info on specializations that might be available to you:

How to become a clinical laboratory technologist?

Due to the elevated level of clinical responsibility in technologist positions, it's important to earn a bachelor's degree if you're planning to pursue this career without any previous professional experience in a medical lab environment. O*NET reports that nearly 60 percent of clinical laboratory technologists active in 2020 had bachelor's degrees, with roughly 5 percent holding master's degrees.

Accuracy and precision are extremely important in these careers, in terms of testing as well as reporting results, and you should have a high level of comfort working with sensitive equipment. Remember to check with your state's occupational authority to find out about licensing requirements.
