LABORATORY MEDICINE
&
The Clinical Laboratory Scientist

"A Test Tube Vision of the Human Body"

What is Laboratory Medicine?
Laboratory medicine is the science, which provides information about the condition of the human body through the analysis of such samples as blood, urine, and other body fluids and tissues. The science encompasses such disciplines as chemistry, microbiology and hematology to name a few.

How is this Information Used?
Laboratory scientists produce data, which aid in the diagnosis and treatment of disease and the assessment of general health. This information assists professionals in variety of medical fields including:
  • Clinical Medicine
  • Industrial Medicine
  • Reproductive Medicine
  • Veterinary Medicine
  • Environmental Medicine
  • Public Health Medicine
How is this Information Obtained?
Initially, a specimen is obtained. Persons involved in specimen acquisition include doctors, nurses, phlebotomists, Clinical Laboratory Scientists and other health practitioners. The specimen is then sent to the laboratory where it is prepared for analysis. The kind of specimen and the information needed determine the type of analysis and the laboratory analyst required. In many cases, the analyst is a Clinical Laboratory Scientist.
 

What is a Clinical Laboratory Scientist?
A person licensed as a Clinical Laboratory Scientist possesses:
  • A Baccalaureate degree
  • Extensive scientific educational background
  • High motivation
  • Technical skills
  • Professional status
The Clinical Laboratory Scientist is a central member of the health care team.

How Does One Become a Clinical Laboratory Scientist?
Completion of a baccalaureate degree from an accredited college or university with a minimum of 16 semester hours in chemistry, 18 semester hours in biological sciences, 3 semester hours of physics or quarter equivalents which include specific required courses. Recommended courses include virology, parasitology, human physiology and anatomy, computer science and statistics. Persons interested in becoming a Clinical Laboratory Scientist must also complete a clinical education program or medical technology trainee program approved by the California Department of Health Services. These programs prepare students with the theoretical and practical skills necessary to enter the field of medical technology. Graduates of the programs are then eligible to sit for the national certifying examinations and the State of California licensure examination.

Update 2006 - The State of California is now reviewing national CLS certification examinations to determine whether California can accept passage of specifically approved exams in lieu of sitting for the California Exam. The goal of this program is to use an approved list of California approved nationally recognized certification exams rather than constantly updating and administering the "California only" CLS exam. The intent is to continue giving the California exam until an adequate list of alternative exams are so approved. All California CLS license applicants will still have to qualify under California Law (coursework and training requirements) but may substitute an approved alternate exam (and a short supplemental quiz on California Law) to fulfill the examination portion of the requirements.

What Is the Employment Outlook for Clinical Laboratory Scientists?
Exciting and diverse career opportunities for the Clinical Laboratory Scientists include employment in:

  • Hospital laboratories
  • Reference clinical laboratories
  • Physician offices
  • Industrial firms
  • Biotechnology
  • Management
  • Education
  • Technical assistance and sales
  • Laboratory information systems
  • Research and development
Most areas of California have employment opportunities with attractive salaries for professionals in clinical laboratory science.

REVIEW BOOKS FOR CLS LICENSURE EXAM

This is a list of possible review materials that may be of help in preparing for the California Clinical Laboratory Scientist Licensure Examination.  This list is not exhaustive and other resources as good or better may also be available.  There is no assurance that familiarity with the listed resources will result in success on the professional licensure and certification examinations.  In the past, prospective examinees have found that their most efficient pre-examination review was based upon review of the texts and resources from their original college and CLS education.  CAMLT makes this list available as a service but has not personally reviewed the listed selections and does not endorse or recommend any of the listed resources.
