Medical Lab Internship Requirements: A Comprehensive Guide

The field of medical laboratory science offers a rewarding career path for individuals passionate about science, technology, and healthcare. Medical laboratory scientists (MLS), also known as medical technologists or clinical laboratory scientists, play a crucial role in diagnosing and treating diseases by analyzing biological specimens and providing vital data to physicians. This article provides a comprehensive overview of medical lab internships and their requirements, covering education, skills, career paths, and available opportunities.

What is a Medical Laboratory Scientist?

Medical laboratory scientists are healthcare professionals who perform scientific testing on a variety of biological specimens, such as blood, urine, and tissue samples. They use sophisticated equipment, including microscopes and automated analyzers, to analyze these samples and report the results to physicians. The data they provide is critical for identifying and treating a wide range of medical conditions, including cancer, heart disease, and diabetes. Medical laboratory scientists work closely with physicians and medical laboratory technicians to diagnose and monitor disease processes, as well as to monitor the effectiveness of therapy.

Medical Laboratory Scientist vs. Medical Laboratory Technician

While both medical lab scientists and medical lab technicians work in the laboratory and perform tests on biological samples, there are key differences between the two roles. A medical lab scientist typically has more education and is able to perform more complex and involved lab work than a medical lab technician.

Medical Laboratory Scientist vs. Medical Laboratory Assistant

A medical laboratory assistant is a subgroup of medical laboratory technician. They are responsible for preparing biological specimens, recording information, and perform more of the lab maintenance tasks such as cleaning equipment and stocking supplies.

Career Opportunities and Work Environment

Medical lab scientists find employment in a variety of settings, including:

Hospitals
Clinics
Forensic or public health laboratories
Pharmaceutical industries
Biotechnology companies
Veterinary clinics
Research institutions

Depending on the setting, their work hours may vary; but typically labs are run 24 hours a day, seven days a week. Medical laboratory scientists spend the majority of their time on their feet, analyzing test results in the lab.

Job growth and security are high for medical laboratory technicians and scientists. According to the Bureau of Labor Statistics, there is currently a shortage of medical lab technicians and scientists in many parts of the country which guarantees ample employment opportunities and sometimes higher salaries for graduates. With additional training and experience, a medical lab scientist can become a department lead or lab manager. Others may seek specializations to advance their careers. Typically, a medical lab technician will progress to a medical lab scientist with more training.

Essential Skills and Qualities

Successful medical lab scientists possess a combination of technical skills and personal qualities, including:

Effective communication skills
Sound intellect
Interest in science and technology
Attention to detail
Analytical and problem-solving skills
Ability to work independently and as part of a team
Strong ethical and professional standards

Educational Requirements and Certification

To become a medical lab scientist, individuals typically need to:

Earn a Bachelor's Degree: Completing a bachelor’s degree in medical technology or clinical laboratory science is the most common path. A bachelor’s degree in a science or health-related field (e.g. biology, chemistry, or microbiology) may also be sufficient, especially if combined with relevant experience or additional training.
Obtain Certification: Most employers require medical laboratory scientists to obtain certification through an accrediting body, such as the American Society for Clinical Pathology (ASCP) Board of Certification (BOC).

Coursework Requirements

Students are eligible for the Extended Internship Bachelor of Science in Medical Laboratory Sciences Program after completing 59 prerequisite credits, including Biology with lab, Anatomy and Physiology with lab, Microbiology with lab, both chemistry with lab courses, and both science electives. However, upon acceptance into the Bachelor of Science in Medical Laboratory Sciences Program, an additional six credits of general education prerequisites must be listed on the student’s degree plan. The program will accept AP, IB or CLEP credits awarded by other institutionally accredited post-secondary academic institutions to fulfill the math and general education coursework. Chemistry, biology and health science courses must be suitable for majors in those disciplines and must include laboratory credit in required courses. The following courses (including labs) are considered equivalent to biology with lab, anatomy and physiology with lab, or microbiology with lab: animal or human anatomy, animal or human physiology, biochemistry, bioinformatics, cell biology, cell physiology, genetics, genomics, immunology, molecular biology, mycology, neuroscience, organic chemistry, parasitology, pathology, pathophysiology, pathogenesis, quantitative analysis, toxicology, virology or zoology. Other courses may fulfill the program’s requirements.

Program Admission

During admission reviews, first consideration may be given to Arkansas residents. Highly qualified applicants from out-of-state are strongly encouraged to apply and may successfully compete for admission.

In order to be admitted to the Bachelor of Science in Medical Laboratory Sciences Program, applicants must possess certain physical, cognitive and behavioral abilities necessary to complete the curriculum. These requirements exist to ensure that students are able to effectively acquire the knowledge and skills needed to become competent and successful laboratory scientists. Students starting this program are strongly encouraged to complete the hepatitis B vaccine series.
