Medical laboratory science combines the basic sciences of biology and chemistry with medicine and the clinical sciences into a very satisfying professional career. Medical laboratory scientists (also known as medical technologists) develop, perform, evaluate, correlate and assure the accuracy and validity of laboratory tests and collaborate with other health care professionals in the diagnosis and treatment of patients. The mission of the medical laboratory science program is to graduate ethical, certified, entry-level medical laboratory scientists with the knowledge and skills necessary to work in all areas of the clinical laboratory including, microbiology, chemistry, hematology, blood banking, immunology, and molecular diagnostics.

The certified medical laboratory scientist is qualified by academic and practical training to work wherever laboratory testing is researched, developed or performed including, hospital, private, research, industrial, biomedical and forensic laboratories, pharmaceutical companies and fertility centers. In addition to laboratory positions, medical laboratory scientists also find careers in infection control, marketing, technical sales and services, laboratory information systems, teaching and consulting.

In partnership with Sinai Hospital of Baltimore, Stevenson University offers a “2+2” baccalaureate program in medical laboratory science consisting of two years of prerequisite courses in the basic sciences and liberal arts, a third year of liberal arts and introductory courses in laboratory medicine, and a fourth year which integrates professional and clinical practicum courses at Sinai Hospital. The clinical practicum provides a bridge between academics and application, allowing students a smooth transition to the workforce as medical laboratory scientists.

The program provides specialized technical training in test performance, correlation of laboratory data and disease management, and practice in problem-solving in the clinical laboratory. Graduates of our program are equipped to seek career enhancement and pursue management positions and/or graduate studies.

The medical laboratory science program is accredited by the National Accrediting Agency for Clinical Laboratory Sciences. (NAACLS); 5600 North River Road, Suite 720, Rosemont, IL 60018-5119; 773-714-8880,

Graduates of the medical laboratory science program earn a Bachelor of Science degree and are eligible to take the national certification examination for medical laboratory scientists offered by the American Society of Clinical Pathology Board of Certification (ASCP-BOC).

Students planning to apply to medical or dental school may want to adopt the pre-medical option of the medical laboratory science curriculum. These students follow the medical laboratory science curriculum with the following additions: Organic Chemistry I and II, and two semesters of General Physics. Students adopting this option of the curriculum are strongly advised to meet with the Health Professions Advisor regarding specific requirements. The student will graduate with a Bachelor of Science in Medical Laboratory Science.

Freshmen and transfer students enter as medical laboratory science majors. The medical laboratory science program accepts only ten students to continue into the junior year of the medical laboratory science major, and selection is determined by the Medical Laboratory Science Admissions Committee.


Upon completion of the Bachelor of Science degree, graduates will be able to:

  1. Demonstrate proficiency in performing the full range of clinical laboratory tests in the contemporary clinical laboratory.
  2. Evaluate test systems and diagnostic algorithms in terms of diagnostic value, compliance outcomes, and cost-effectiveness.
  3. Evaluate the results of laboratory analyses for accuracy and validity, and correlate laboratory data to disease processes.
  4. Apply the principles and practices of quality assurance/quality improvement as applied to the pre-analytical, analytical, and post-analytical components of laboratory services.
  5. Exhibit the ethical and professional behaviors required within the healthcare delivery system.
  6. Communicate effectively orally, in writing, and through laboratory information systems in order to consult with members of the healthcare team, to provide patient education and customer service, and to interact with external parties.
  7. Use research design/practice skills to evaluate published studies and investigate clinical laboratory issues/problems.
  8. Exhibit an understanding of the concepts and principles of laboratory management such as human resource management, finance, operations, regulatory compliance, performance improvement, critical pathways and clinical decision-making.
  9. Demonstrate understanding of education techniques and terminology to train/educate users and providers of laboratory services.
  10. Seek national certification as a Medical Laboratory Scientist and pursue employment within this field or a related field or continue to post-graduate education.


Students must earn a minimum cumulative GPA of 2.80 to be admitted into the Medical Laboratory Science program. The lowest acceptable grade is a "C" in all courses listed in the catalog under "Major Requirements" for the major, including both courses in the major and SEE courses required by the major. No student, regardless of major, will be permitted to take a science or math course unless he/she earns a grade of "C" or better in all prerequisite courses.

After admission into the junior year of the program, students must maintain a minimum GPA of 2.50 in the major to remain in good standing and to be eligible for admission to the clinical practicum. A student whose GPA is less than 2.50 will be reviewed by the Medical Laboratory Science faculty for continuance in the program.

No student will be permitted to take a science, math or MLS course unless he/she earns a grade of "C" or better in all prerequisite courses.

A student may not earn a grade of “D” or lower in any science, math or MLS course more than three times during the program. If a fourth grade of “D” or lower is earned in any science, math or MLS course, the student will be automatically dismissed from the Medical Laboratory Science major.

Probation: The student who earns any combination of two grades of “D” or lower in a science, math or MLS course will be notified, in writing, by the program coordinator that he or she is on probation in the Medical Laboratory Science program.

Final Probation: The student who earns any combination of three grades of “D” or lower in a science, math or MLS course will be notified, in writing, by the program coordinator that he or she is on final probation in the Medical Laboratory Science program.

Dismissal: If a fourth grade of “D” or lower in any science, math or MLS course is earned, the student will be notified, in writing, by the program coordinator that he or she has been dismissed from the Medical Laboratory Science major.

Final Exam Policy

A score of 73% must be achieved on the final exam in each senior-level medical laboratory science course to be able to proceed to the corresponding clinical practicum course. If a student does not pass the relevant final exam the first time with a 73% or better:

  1. The first score on the exam is used to calculate the final grade in the course.
  2. Student's corresponding clinical rotation schedule may be adjusted.
  3. Student will be allowed to retake a different exam a maximum of two times.
  4. Student must pass the retake exam with a score of 73% or better. If the student fails to earn a 73% on the retake exam after two attempts, he/she is required to repeat the course.

Competency Exam Policy

  1. The minimum passing score for each competency exam is determined by each instructor (80-100%).
  2. A student who does not achieve the minimum passing score will have a second opportunity to achieve a passing score. However, the score that will be used for the final grade computation will not exceed the minimum passing score, regardless of the score on the second competency exam.
  3. If a student fails the competency exam a second time, he or she will be counseled by the program coordinator and faculty member. The outcome could result in repeating the entire course.

Medical Requirements

Students enrolled in Medical Laboratory Science (MLS) courses will have potential exposure to blood-borne pathogens or other potentially infectious materials and may be at risk of acquiring hepatitis B virus (HBV). Also, during the course of the Medical Laboratory Science program, students may have direct patient contact. The program requires the student to demonstrate effective vaccinations prior to starting the Medical Laboratory Science (MLS) courses (except MLS 210).

All full-time, part-time and categorical certificate students admitted to the junior (3rd) year of the Medical Laboratory Science program must submit the Stevenson University Student Health Form to the Wellness Center.  The form is on the Wellness Center website.

In order to ensure compliance with the medical requirements outlined below, the Stevenson University Medical Laboratory Science Program uses a third party vendor, Castlebranch, Inc. to manage student immunizations, compliance documents, proof of insurance, background checks and drug screens. The cost to create a Castlebranch profile and upload the required vaccination and titer information is approximately $25 and is a one-time fee.

Students must provide evidence of immunity to Varicella (chicken pox), Measles, Mumps, and Rubella (MMR).

  • Documentation of 2 doses of vaccine
  • Laboratory evidence of immunity = Positive titer OR
  • Laboratory confirmation of disease OR
  • Healthcare provider's diagnosis of disease

Documentation of immunity to Hepatitis B (HepB)

  • HepB immunization series (3 doses) AND
  • Laboratory evidence of immunity: anti-HBs titer = > 10mlU/mL (anti-HBs = Hepatitis B surface antibody)
  • If anti-HBs titer = < 10mlU/mL, student MUST:
    • Receive 1 booster dose of HepB vaccine AND
    • Have a repeat titer within 1-2 months after receiving booster dose.
  • If repeat anti-HBs titer = < 10mlU/mL, student MUST:
    • Receive 2 booster doses of HepB vaccine AND have a 2nd repeat titer within 1-2 months after receiving booster dose.
  • If 2nd repeat anti-HBs titer = < 10mlU/mL, student MUST receive counseling by their healthcare provider regarding their risk of acquiring hepatitis B.

Students may choose to decline the hepatitis vaccine, but he/she must sign the Hepatitis Declination Form (on the SNHP portal) and as documentation of understanding the risk of acquiring hepatitis B.

Students must provide documentation of personal medical insurance in the junior year of the program.  Students are financially responsible for any costs incurred due to illness or injury experienced by the student, in conjunction with the student labs and clinical practicum.

Students enrolled in MLS courses (except MLS 210) must submit documentation of all required immunizations and titers listed in the Supplemental Health Form found on the SNHP portal or on the Castlebranch website by July 1 for fall courses and January 2 for spring courses. If the documentation of immunizations and titers or signed declination form is not on file by the deadline, the student will be dropped from any registered MLS course.

Students entering the senior (4th) year of the program must upload to their Castlebranch profile documentation of a negative tuberculosis screening test (PPD or chest x-ray) prior to the start of classes in the fall semester.

An annual influenza immunization (free of charge to seniors at Sinai Hospital in fall) is required by the hospital and clinical practicum affiliates. Evidence of immunization must be uploaded to the student’s Castlebranch profile.

A criminal background check and drug screen must be obtained through Castlebranch by July 1 of the senior year and costs approximately $80. Be advised that criminal background checks and drug screens are only valid for one year; therefore, the student should schedule these so they remain valid until graduation.

Clinical Practicum

The clinical practicum is scheduled in the spring semester of the senior year. It is divided into four discipline-specific rotations and is scheduled for five days a week, eight hours a day.

Students may be assigned to clinical departments at the following affiliates:

  • Sinai Hospital
  • Northwest Hospital
  • Carroll Hospital
  • Greater Baltimore Medical Center
  • Johns Hopkins Hospital
  • Baltimore Washington Medical Center

Students must provide their own transportation to the clinical affiliates, which may include paying for parking.

Personal protective equipment is provided by the facilities.

Liability insurance is purchased by the University to cover students during their clinical practicum.

The clinical practicum culminates in a final comprehensive exam as preparation for the national certification examination for Medical Laboratory Scientists. Students will not substitute for or replace laboratory personnel in turning out routine workload during their specified hours at the clinical site. After demonstrating proficiency, students, with qualified supervision, may be permitted to perform procedures. It is permissible; however, for the clinical site to hire students to perform laboratory procedures outside the regular rotation hours.

Program Completion

Upon satisfactory completion of the required program of study, the student will be awarded a Bachelor of Science in Medical Laboratory Science. The granting of the degree is not contingent upon passing any external certification examination.

National Certification Examination

Program graduates are eligible to take the national certification examination for Medical Laboratory Scientists offered by the American Society for Clinical Pathology Board of Certification (ASCP-BOC).

Program Admission Requirements

Freshmen and transfer students enter the University as medical laboratory science majors. The Medical Laboratory Science Program accepts only 10 students to continue into the junior (3rd) year of the program, and selection is determined by the Medical Laboratory Science Admissions Committee.

Consideration for admission to the MLS program in the spring semester of the sophomore year is based on the following criteria:

  • Minimum cumulative GPA of 2.80 in all university work attempted
