While physical examinations and diagnostic images like x-rays can certainly help diagnose illnesses, the medical test has become integral to the practice of modern medicine. Laboratory science technologists and technicians are the professionals responsible for running these tests which help medical professionals understand our physical state. Laboratory technologists prepare tissue, blood, and other fluid samples for clinical tests, and they help decide which tests are appropriate for particular samples and patients. They examine samples using microscopes, and use chemical and biological principles to determine the makeup of these samples. Laboratory technicians provide assistance and perform less complex tasks than technologists, such as drawing blood or doing manual tests via written instructions.

Clinical laboratory technologists need a bachelor's degree in medical technology or a life science in order to begin their career; technicians need a certificate or associate's degree. These programs include courses in math, computer applications, statistics, microbiology, chemistry, and clinical skills. Some states require licensure or registration after completing an educational program. Many professional groups also offer voluntary certification programs for laboratory technologists, via written or computer examinations.

What are some of the specializations within this degree program? 

  • Laboratory Technologist: Laboratory technologists perform medical and scientific tests on tissue and other samples, to aid in disease diagnosis. In smaller labs, these professionals may perform a whole range of tests, using computer technology to analyze the results.
  • Laboratory Technicians: Also known as medical technicians, these workers provide assistance to laboratory technologists. They may help with less complex tasks, such as preparing samples or performing manual tests.
  • Laboratory Chemistry Technologists: As their name implies, these specialized lab technologists use principles of chemistry to analyze samples. They may check for particular levels of chemicals or hormones in tissues or blood.
  • Cytotechnologists: These technologists work specifically on cancer detection. They prepare slides with tissues and cells, to look for anomalies and other signs of cancer under a microscope.
  • Phlebotomists: Phlebotomists are a particular type of lab technician, tasked with collecting blood samples. They are trained in drawing blood in various manners, for different types of tests.
  • Histotechnicians: In order to aid pathologists in examining tissue for disease, histotechnicians prepare tissue samples for examination under a microscope. They cut the tissue appropriately and stain it for easier viewing.

What degree levels are available?

  • Certificate: 1 to 2 years to complete
  • Associate's Degree: 2 years to complete
  • Bachelor's Degree: 4 years to complete

What are the educational and certification requirements? 

You'll either need an associate's or bachelor's degree, depending on the laboratory science position you desire. Laboratory technologists need at least a bachelor's degree in a relevant field; specific medical technology programs are available, although life science degrees such as biology, microbiology, chemistry, or biochemistry also provide good preparation for this type of career. Specialized medical technology programs typically require students to take an interdisciplinary coursework in math, computer applications, biology, chemistry, and clinical laboratory techniques.

Laboratory technician positions generally require a certificate or associate's degree in laboratory technology. These are available through community colleges, hospitals, technical schools, and allied health organizations, and cover a less extensive version of the coursework in the medical technology bachelor's degree programs. There are several accrediting bodies which recognize programs in medical technology and particular laboratory science areas, including the National Accrediting Agency for Clinical Laboratory Science Schools (NAACLS), the Commission on Accreditation of Allied Health Education Programs, and the Accrediting Bureau of Health Education Schools. 

Some states require licensure, certification, or registration of laboratory science professionals; however, the nature of this licensure varies by state, and individuals should check their state's department of healthcare professions to find the information that is relevant to them. There are voluntary certifications available through the National Credentialing Agency for Laboratory Personnel, the American Society for Clinical Pathology, the American Association of Bioanalysts, and other professional groups. Some employers prefer to hire technologists and technicians with voluntary certification. (BLS)

What kinds of classes will I be expected to take?

  • Foundational Science: Students in laboratory science need a strong foundation in basic life sciences in order to fully comprehend the tests they will be completing. Courses in microbiology, Hematology, and chemistry are required.
  • Computers & Analysis: Classes like software applications and statistics teach students the skills for interpreting lab tests. Students learn how to evaluate test results and chart their findings.
  • Clinical Lab Skills: Laboratory components to natural science classes are important for mastering the concepts and gaining dexterity. Students practice running tests and observing results.
  • Clinical Specialization Courses: Depending on your desired career, you may specialize your degree with electives in particular clinical areas. For example, those interested in clinical pathology could take additional advanced classes in immunology.
  • Clinical Practicums: Practicums allow students to put all their previous lab and classroom skills together to perform mock versions of real clinical tests. This hands-on aspect prepares them for the job market and the sensitive nature of this profession.

What are the on-site training requirements?

All laboratory science students can expect some amount of hands-on clinical work in their degree program. However, the extent of this requirement will vary by degree, one's specialization, and their state's requirements. Bachelor's programs generally have around a full year of clinical practicums.

What are some other degrees that are related to this program?

  • Ultrasound Technicians: These professionals use sonogram machines to develop images of a patient's tissues. They calibrate the machine, situate the patient, and select the best images to give to the physician.
  • Radiology Technologists: These technologists work with patients, to perform diagnostic tests. They are generally trained to do MRIs, CT scans, and mammograms.
  • Medical Assistants: Medical assistants help doctors and nurses with both clinical and administrative tasks. They may prepare patients for exams, take medical histories, and schedule appointments.
  • Cardiovascular Technicians: These clinical technicians assist with disease diagnosis related to the human heart. They may perform EKGs, administer stress tests, or do other assistive diagnostic work.
  • Physician Assistants: Physician assistants are trained in more complex clinical tasks. This profession generally requires a master's degree and more training than the medical assisting occupation.
