Medical technologists are responsible for operating and maintaining the equipment that is used to look at samples or specimens. They make sure that all tests are done the right way and in a timely manner.
A medical technologist’s training is more extensive than what is required of medical lab technicians. Medical technologists do not often interact directly with patients, but their work is necessary for the diagnosis, treatment, and care of patients.
This article will go over what a medical technologist does. You will learn about the different paths a person can take if they want a career in medical technology, including the education and certification that is required to be a medical technologist.
Medical Technology Concentrations
Medical technologists work in all areas of the lab, including immunology, microbiology, genetics, histology, hematology, chemistry, toxicology, and blood banking.
The role of a medical technologist is usually determined by the branch of pathology that their lab specializes in, but is otherwise only limited by the tools they have to work with. The main purpose of their work is to help providers make diagnoses.
Clinical Pathology
In clinical pathology, a medical technologist would conduct and oversee lab tests done on body fluids and tissues. The tests are done to look for markers of infectious and non-infectious diseases.
The kinds of specimens a medical technologist will look at include:
Blood Urine Sputum (phlegm) Stool (feces) Spinal fluid Pleural fluid Peritoneal fluid Joint fluid Bone marrow
Anatomical Pathology
In anatomical pathology, a medical technologist would look at tissues taken from the body during a biopsy or surgery.
While some of the diagnostic tests can be done by the technologist, others require the expertise of a pathologist.
The technologist can help with exams including:
Gross examination (looking at tissue with the naked eye)Histology (looking at tissue under a microscope)Cytopathology (looking at loose cells under a microscope)Electron microscopy (using special high-resolution microscopes to look at samples)Cytogenetics (looking at chromosomes with special technology)
Medical Technologist Expertise
Medical technologists prepare tissue samples, slides, and cultures for the pathologist to look at. By doing these tasks, they help streamline the diagnostic process and make it possible for lab results to come back quickly.
In larger facilities, medical technologists will do more complex tasks, such as molecular, genetic, or genomic testing. They can also step in to help when there are diagnostic challenges, like uncommon or confusing lab findings.
Medical technologists typically work under a pathologist but can also work independently and be tasked with operating a lab.
In this role, medical technologists will oversee the work of lab technicians as well as manage their own duties.
Although the pathologist is ultimately in charge of the lab and its staff, the medical technologist will generally be the one who makes sure that the lab runs smoothly, safely, and properly on a day-to-day basis. This includes tasks like setting up, calibrating, and sterilizing lab equipment, as well as analyzing and checking the accuracy of lab reports.
Most medical technologists work behind the scenes and do not have direct contact with patients.
The health professionals who get patient specimens are usually phlebotomists and lab assistants, and some specimens are delivered directly to the lab by providers and surgeons.
Medical Technology Subspecialties
Some medical technologists work in a narrow field of practice. For instance, some labs specialize in genetics or cytopathology. Other labs may have specific roles and functions within a hospital or institutional setting.
Transfusion Medicine
A medical technologist working in transfusion medicine makes sure that there is enough of a safe supply of blood in a blood bank.
They may also do blood typing and screening for infectious diseases, such as HIV and viral hepatitis.
Forensic Pathology
In forensic pathology, a medical technologist may help review the clinical and anatomical evidence after a person’s sudden, unexpected death.
The forensic pathologist is responsible for getting specimens (such as clothing fibers or tissue from a body), but the medical technologist would run many of the tests that are needed to determine the cause of death.
Organ-Specific Pathology
There are pathology subspecialties that focus on specific organs or physiological systems.
A medical technologist working within these subspecialties would usually require extra training to learn about the different diseases that affect an organ system and how those diseases are diagnosed.
For example, a medical technologist might focus on:
Cardiovascular pathology (heart and circulatory system) Endocrine pathology (glands that produce hormones) Gastrointestinal pathology (digestive tract) Genitourinary pathology (genitals and urinary tract) Gynecological pathology (female reproductive system) Neuropathology (brain and nervous system) Oral and maxillofacial pathology (mouth, jaw, and related structures) Orthopedic pathology (bones, joints, and related structures) Pulmonary pathology (lungs) Renal pathology (kidneys)
Medical Technologist Training and Certification
To become a medical technologist you need at least a bachelor’s degree, preferably in medical technology.
Students who majored in or obtained a degree in another science—such as biology, microbiology, or biochemistry—and who are interested in being medical technologists can often take hospital-based courses during their senior year of college if offered.
Before working as a medical technologist, a person is required to either complete a medical technologist program accredited by the National Accrediting Agency of Clinical Laboratory Science (NAACLS) or meet other requirements, including relevant certification and a certain number of years of clinical laboratory experience “in an acceptable laboratory.”
Medical technologists should get certified once they have finished all of their educational and training requirements.
The American Society of Clinical Pathologists (ASCP) offers a national certification exam for medical technologists that should be renewed every three years.
This certifies that a medical technologist is very skilled in their field. It also allows them to list their credentials after their name:

Summary
A medical technologist is a health professional who has been trained to do tests on samples of fluids and tissue to help diagnose diseases. While they do not usually interact with patients, the work they do in the lab is very important for patient care.
Medical technologists need a lot of education, training, and certification to do their job well. They can also choose to focus on a certain area of medical technology that they are especially interested in, like forensic pathology or transfusion medicine.
You will need to understand human anatomy and physiology, as well as more technical aspects of using lab equipment. For this job, it will also be important that you can stay organized, work independently, and manage your time well.
However, the salary of a medical technologist will also depend on where they work and whether they are specialized.
