Clinical Lab Science

Clinical Laboratory Science Overview

The Clinical Laboratory Science program prepares students to become licensed clinical laboratory technologists. Technologists discover the presence or absence of disease in collected samples, and provide data that help physicians determine the best treatment for a patient. 

CLS students will take three years of general education, basic and advanced science courses, followed by a clinical year that combines professional internships at regional hospital clinical laboratories with coursework. 

Students who have a bachelor’s degree in a biological or chemical science can complete the program in 12 months provided they have all the required pre-requisites at the time of admission.

Mercy College’s program in Clinical Laboratory Science is registered with the New York State Education Department as a licensure-qualifying program. The American Society for Clinical Pathology (ASCP) Board of Certification administers certifying examinations and awards certification.

  • Hospital-based and private diagnostic clinical laboratory scientists*
  • Biotechnology
  • Laboratory research technicians (academia, industry, or government)
  • Pharmaceutical research (Research and Development)
  • Education
  • Laboratory Informatics

*Because there is currently a shortage of trained medical clinical laboratory scientists available to staff clinical diagnostic laboratories, the employment opportunities in this field are excellent.
Go to the U.S. Department of Labor for a detailed description of this profession and current job outlook projections and national median wage data.

Continuing career development is supported by the following professional organizations:

Clinical laboratory scientists who obtain a master's degree in an area of expertise (e.g. microbiology) or in management or health administration may advance to positions in clinical laboratory administration.

Students can also choose to pursue an advanced practice degree, a Doctorate in Clinical Laboratory Science.

Frequently Asked Questions

What is Clinical Laboratory Science?

Clinical Laboratory Science (CLS) deals with the testing of body fluids for the diagnosis of disease and identification of pathogens. Graduates who obtain this bachelor’s degree are eligible to become licensed in New York State as clinical laboratory technologists. In contrast, graduates of community college programs offering associates degrees in this field can become licensed as Clinical Laboratory Technicians.

When can I apply to the Clinical Laboratory Science program?

Students can declare their major as early as their freshman year. It is advised that students considering the CLS program contact the Program Director as early as possible to plan their course of study.

You can declare CLS as your major on your admission application.

I already have a bachelor’s degree from another college; what do I need to do?

You can apply directly to the second degree CLS program if you have all the required pre-requisites which are:

  • General Biology with lab – 8 credits
  • General Chemistry with lab – 8 credits
  • Organic Chemistry I and II with lab – 8 credits
  • Biochemistry with lab – 4 credits
  • Microbiology with lab – 4 credits
  • Human Physiology with lab – 4 credits
  • Immunology – 3 credits
  • Molecular Biology with lab -4 credits
  • Statistics - 3 credits

Once you have all the required pre-requisites and are accepted to the program, you can complete the program in 12 months (3 semesters)

I have an associate degree as a Medical Laboratory Technology. What are my next steps if I want to get my bachelor's degree?

You can apply for the traditional CLS program. Transfer students will receive credit in transfer upon matriculation at Mercy College. Credit is usually transferable for all courses the applicant obtained a grade of “C” or higher. The program director or designee will determine if clinical courses are transferable to the program at Mercy College

Can I attend the program part-time?

This program has been designed for the part-time or full-time student. The program is designed to be flexible enough to accommodate working adults and many students attend part-time. Mercy College campus-based courses are scheduled for a combination of evenings, days, and/or weekends and can be completed on a part-time basis. However, the clinical internship requires a full-time commitment and cannot be combined with a full-time job.

Should I finish the general education requirements before starting my major?

No! Because of the rigor of the program a combination of general education courses and major-level courses is recommended. Students should contact the Program Coordinator as early as possible to plan their course of study.

What is the first step in the Clinical Science admissions process?

Click on "Apply Online" and complete the application for admission to Mercy College, or call 1-877-MERCY GO to arrange for an appointment with an Admissions Counselor. If you bring your completed application form and copies of your high school and/or college transcripts with you at the time of your appointment, the Admissions Counselor will evaluate your transcripts and make an acceptance decision. In addition, you may be required to take the Mercy College Placement Examination, which is used to place students in appropriate-level mathematics and English courses. If applicable, an appointment to take this exam will be scheduled at the time of your interview. Once you have met with an Admissions Counselor and taken the Placement Examination, you will meet with an Academic Advisor to plan a course schedule for your first semester at Mercy College.

How is Mercy's program unique?

We offer a flexible schedule that helps meet the demands of students working full time. Our small class size facilitates a close relationship among the students and between students and faculty.

What type of student is well-suited for the program?

The curriculum is academically rigorous and scientifically oriented. It is especially designed for the motivated learner who can successfully pursue an intense educational experience. The program combines strengths in biology, chemistry and the biomedical sciences. Integration of several disciplines is key to success in the program.

Are department faculty available for academic advising?

Yes, faculty are always ready to help students with questions about what courses to take, the sequencing of courses, and career opportunities, including internships and cooperative education.

If I plan to go to graduate school, is this the program for me?

If you plan to pursue graduate education, the program will prepare you for both master's and doctorate level work. Depending on the area of emphasis of the graduate program you choose, additional courses in biochemistry or physics may be required.

Being a CLS can be a great first degree if interested in pursuing a graduate degree in medicine or as a Physician Assistant. You will have first-hand knowledge of laboratory testing, why it is performed and how to interpret the results. The clinical background can be helpful to you in medical and PA school.

How long does earning a degree take?

Full-time students can complete the 129-credit degree program in four years.

Students who are second degree applicants and have all the required pre-requisites can complete the program in 12 months (3 semesters).
