A medical laboratory scientist is a laboratory professional who performs scientific testing on biological specimens. Depending on the laboratory and specialty, testing may involve blood, body fluids, tissues, microorganisms, cells, or molecular material.
Medical laboratory science can involve several scientific disciplines, including:
- Clinical chemistry
- Hematology
- Microbiology
- Immunology
- Immunohematology and blood banking
- Molecular diagnostics
- Urinalysis and body-fluid analysis
- Laboratory quality management
What Does a Medical Laboratory Scientist Do?
The daily responsibilities of a medical laboratory scientist depend on the laboratory department and specialty.
Typical activities may include:
- Receiving and processing specimens
- Performing laboratory tests
- Operating laboratory instruments
- Analyzing test results
- Following laboratory procedures

Laboratory professionals work according to established procedures and quality standards. The exact scope of practice depends on the occupation, laboratory, employer, and applicable regulations.
Why Choose a Medical Laboratory Science Career?
This field may suit students who enjoy scientific investigation but prefer laboratory-based work rather than a primarily patient-facing role.
Medical laboratory science can combine biology, chemistry, microbiology, technology, data interpretation, and healthcare.
Major Areas of Medical Laboratory Science
1. Clinical Chemistry
Clinical chemistry involves laboratory analysis of chemical components in biological specimens. Tests can provide information about physiological processes and health conditions.
2. Hematology
Hematology focuses on blood, blood cells, and related biological processes. Laboratory professionals may analyze blood-cell characteristics and other hematological measurements.
3. Clinical Microbiology
Clinical microbiology involves laboratory study of microorganisms associated with human health and disease. It can include bacterial, fungal, parasitic, or other microbiological investigations depending on the laboratory.
4. Immunology
Immunology-related laboratory work involves biological processes associated with the immune system. Testing may examine antibodies, immune responses, or other relevant biological markers.
5. Blood Banking
Blood-bank and transfusion-related laboratory work involves testing and processing associated with blood and blood components. Because this work can have significant clinical implications, specialized training and applicable requirements are important.
6. Molecular Diagnostics
Molecular diagnostics uses molecular methods to analyze biological information. Depending on the laboratory, professionals may work with DNA, RNA, genetic markers, or other molecular targets.
Medical Laboratory Scientist vs. Medical Doctor
These are different healthcare career pathways.
A physician is a licensed healthcare professional who evaluates patients, diagnoses medical conditions, and provides treatment within their scope of practice.
A medical laboratory scientist is a laboratory professional who performs scientific testing and analysis that can support healthcare decisions.
A biology or laboratory science degree does not by itself qualify someone to practice medicine.
Education for Medical Laboratory Scientist Careers in the USA
Education requirements depend on the exact occupation and employer. Relevant academic backgrounds can include medical laboratory science, clinical laboratory science, biology, chemistry, microbiology, and related scientific disciplines.
Students should carefully check whether a particular degree program meets the requirements for the professional credential or job they intend to pursue.
Bachelor's Degree
A bachelor's degree in medical laboratory science or a related scientific field can provide foundational knowledge in biology, chemistry, microbiology, hematology, immunology, and laboratory methods.
