Clinical Laboratory Scientist (CLS) / Medical Technologist (MT)

Physicians have many tools to help diagnose and treat their patients. One of the first things many doctors do when evaluating a patient is order laboratory tests such as blood work, biopsies, and urinalysis. While running some of these tests can be relatively straightforward, some tests require a high degree of expertise and skill. These crucial tests that can help diagnose cancer, diabetes, and infectious disease are performed by trained clinical laboratory scientists (CLS) and medical technologists (MT)—titles often used interchangeably.

However, it’s not just about running tests. CLS/MT professionals must follow strict quality standards to ensure the accuracy and reliability of their results.

They are responsible for maintaining and operating laboratory equipment, managing inventories, and updating laboratory procedures to keep up with advances in technology and medical knowledge. They also help monitor the effectiveness of treatments and medications, ensuring patients receive the appropriate care.

Professionals must complete a four-year bachelor’s degree program in medical laboratory science or a related field to start in this field. This degree should include coursework in biology, chemistry, and mathematics. Not only is a degree required to be able to perform the job duties, but it is also required for national certification and may be required for licensure. 

The demand for CLS and MTs is growing. As the population ages, there is an increased need for medical professionals to diagnose and treat illnesses, increasing the demand for trained  CLS and MTs who can perform complex tests. The Bureau of Labor Statistics (BLS 2022) predicts a 7 percent growth in employment from 2021-2031. This growth rate is slightly higher than the national average of 5 percent for all occupations.

CLS and MTs can pursue various specializations, such as clinical chemistry, hematology, microbiology, immunology, molecular biology, and histotechnology. Degree types for CLS/MT professionals range from at least a bachelor’s degree to doctoral degrees, with higher levels of education often leading to advanced positions or research opportunities. 

Alternatively, military personnel who have completed a 50-week US military medical laboratory training course can obtain certification and work in this field. 

Admissions requirements for CLS and Medical Technologist MT programs vary depending on the degree level and institution. Generally, applicants must have a strong foundation in science and mathematics. Bachelor’s degree programs may require standardized test scores such as ACT or SAT, minimum GPA, and specific high school coursework. 

More advanced programs such as master’s or doctorate may require prerequisite coursework in biology, chemistry, and mathematics courses. Additional requirements for graduate programs include a minimum GPA, letters of recommendation, a personal statement, and relevant work or volunteer experience in a healthcare setting. Some programs require standardized test scores, such as the GRE.

Program accreditation is essential to ensure that the education provided meets established quality standards in the field. CLS and MT programs are accredited by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS). The NAACLS evaluates and approves programs based on curriculum, facilities, faculty qualifications, and program outcomes. Attending an accredited program offers students a high-quality education, ensures eligibility for certification exams, and enhances employability within the healthcare industry.
