Clinical Laboratory Sciences

Diseases and disorders of the human body can be detected by laboratory examination of body fluids and tissues. Diagnosis of diseases, such as leukemia, diabetes, anemia, AIDS (acquired immune deficiency syndrome), and bacterial or parasitic infections, can be made by using sophisticated methods of analysis and evaluation. In addition, laboratory examinations can detect pregnancy, show the presence and amount of various drugs or alcohol in the body, and determine blood type. Microscopic examination of the tissues in the body is used in the diagnosis of diseases, tumors, and abnormalities of all the organs.

Clinical laboratory personnel conduct and evaluate these procedures in order to provide the physician with the information necessary to make an accurate diagnosis. Technologists and technicians provide a wide range of laboratory services depending upon their skill and education. Tests may be routine or highly complex analysis using the most advanced technology and equipment available.

Many careers and specialties are available in the clinical laboratory, with educational requirements ranging from two years of training after high school to several years of postgraduate training.


Medical Technologists perform laboratory
procedures used in the diagnosis and
treatment of disease.




Cytotechnologist

Cytotechnologists are trained laboratory technologists who use special techniques to study the structure and function of cells in the human body. By examining cells using a microscope, they can detect changes that occur during the progression of diseases, such as cancer. To enter a 12-month clinical internship program in cytotechnology, the student first must complete three years of college. These programs, offered in some hospitals and colleges, teach students to use a microscope to examine cell samples that have been specially stained, and to recognize and identify changes or abnormalities in cell size, shape, structure, or location.

Work Activities

  • Preparing slides of cell samples for examination by using special staining techniques that make the cells easier to differentiate
  • Examining smears of cell samples on slides using a microscope
  • Detecting abnormal hormone conditions
  • Recognizing minute abnormalities in the color, size, and shape of cellular components and patterns


Work Settings
Most Cytotechnologists work in hospitals, clinics, or private laboratories under the supervision of a pathologist. Different kinds of diseased tissue specimens and unpleasant odors often are present, but few hazards exist because safety procedures generally are employed in laboratories. Some Cytotechnologists work in a university setting as professors or researchers.

Special Requirements
Although Cytotechnologists do not need a license to practice in New Mexico, graduates of accredited cytotechnology programs may apply to the Board of Registry of the American Society of Clinical Pathologists (ASCP) to take the certification examination. An individual who meets the requirements of the Board is recognized as a registered Cytotechnologist.

Histology Personnel

Histotechnologists and Histologic Technicians prepare human or animal tissue samples for microscopic and other types of examination for use in diagnosis, research, or instruction. This work enables pathologists to diagnose dysfunction, disease, and malignancy. Histotechnologists, also called Histologists, perform complex procedures and often are supervisors or instructors. Histologic Technicians perform routine specimen preparation procedures and assist Histotechnologists.

Work Activities

  • Preparing sections of body tissue for diagnostic, research, or teaching purposes
  • Embedding pieces of tissue in wax, then slicing very thin sections using a microtome
  • Mounting thinly-sliced tissue onto a glass slide for microscopic study
  • Processing tissue sections by fixation, dehydration, decalcification, microincineration, and staining
  • Identifying tissue structures and cell components
  • Managing and supervising the histology laboratory

Work Settings
Most Histologic Technicians and Histotechnologists work in the pathology laboratory of a hospital or clinic. Some may work in medical or research laboratories. Specimens of diseased tissue and hazardous, odorous chemicals are encountered daily. However, strict precautionary procedures are used to assure safety and to minimize risks.

Special Requirements
There are three ways for Histologic Technicians to achieve certification by the American Society of Clinical Pathologists (ASCP). They can complete an accredited program in histotechnology, earn an associate degree and complete one year of clinical laboratory experience in histopathology, or earn a high school diploma and complete two years of clinical laboratory experience in histopathology. Also, they must pass an examination given by the ASCP.

To be certified by the ASCP, Histotechnologists must have a bachelor degree in an approved major. Then, either one year of experience in a histopathology laboratory or the completion of a formal histologic technology educational program is required. They also must pass an examination given by the ASCP.

the year 2000.



Medical Laboratory Personnel

Medical Technologists and Medical Laboratory Technicians perform essential laboratory testing that is critical to the detection, diagnosis, and treatment of diseases. Their work includes the use of microscopes, chemicals, computers, and complex laboratory equipment and instruments. They can perform tests in all sections of the laboratory, including hematology, bacteriology, chemistry, urinalysis, serology, immunohematology, forensic pathology, and toxicology.

Medical Laboratory Technicians perform procedures that require less technical or theoretical knowledge than those performed by Medical Technologists.

Work Activities
Medical Laboratory Technicians' activities may include:

  • Performing laboratory procedures used in the diagnosis and treatment of disease
  • Collecting blood specimens
  • Using laboratory equipment, such as microscopes and computerized instruments, for automated analysis
  • Inoculating culture media to identify bacteria
  • Monitoring the quality control of tests and procedures
  • Reporting unusual or abnormal results to a Medical Technologist or pathologist
In addition to any testing that can be performed by Medical Laboratory Technicians, Medical Technologists' activities may include:
  • Performing complex and sophisticated laboratory analysis
  • Evaluating the effects that a patient's physiological condition may have on the results of the tests performed
  • Confirming test results and providing the physician with the necessary data to determine the presence, extent, cause, and treatment of the disease
  • Designing, establishing, and monitoring quality control programs to ensure the accuracy and reliability of test results
  • Assuming the responsibility for accurate results


Career Specialties
Most Medical Technologists and Medical Laboratory Technicians are generalists who work in all areas of the laboratory. With additional education, they can become specialists in particular areas of laboratory work, including:

Clinical Chemistry: qualitative or quantitative analysis of the chemical constituents of body fluids, including toxic substances, cholesterol, drugs and alcohol, blood sugar, and enzymes Hematology: analysis of blood cells and plasma to detect diseases, such as leukemia and anemia

Immunohematology: study of antigens and antibodies found on blood cells and in plasma in order to provide safe blood and blood products for transfusion Microbiology: identification and evaluation of the bacteria, viruses, fungi, and parasites associated with infectious diseases

Immunology (Serology): analysis of serum and body fluids in order to study the body's immune response to infectious and autoimmune diseases


Work Settings
Medical Laboratory Personnel work as part of a team. Medical Laboratory Technicians and Phlebotomists (persons who are trained to collect blood samples) are supervised by Medical Technologists. Medical Technologists are supervised by the Chief Medical Technologist or Laboratory Director, and the pathologist.

Most Medical Laboratory Personnel work in hospital laboratories. Many are employed by private physicians, public health laboratories, medical research facilities, pharmaceutical companies, universities, industrial medical laboratories, and the armed forces.

Hazards include working with diseased tissues, close contact with patients who have infectious diseases, exposure to toxic agents, and unpleasant odors. Risks are minimized by properly handling materials and using approved safety precautions.


Special Requirements
To become Medical Laboratory Technicians, individuals must have formal clinical training or an associate degree in medical laboratory technology that includes clinical training.

To become Medical Technologists, individuals must have a combination of formal clinical training and experience, an associate degree plus experience, a baccalaureate degree plus clinical training, or a baccalaurate degree in medical technology.

In addition, individuals seeking to become technicians or technologists must pass a national certification examination given by the Board of Registry of the American Society of Clinical Pathologists, or the National Certification Agency for Medical Laboratory Personnel, or the American Medical Technologists. Certification also is available through the International Society for Clinical Laboratory Technology (ISCLT). Specific requirements regarding levels of formal education vary with each employer. It is recommended that a counselor be consulted for advice on coordinating certification with career goals.
