Medical Laboratory Science (MLS), formerly known as Clinical Laboratory Science (CLS), professionals generate, interpret and report test results vital in making a timely and accurate diagnosis. Attention to detail and problem solving skills are highly valued in this profession.

Some MLS professionals work as generalists, which means they work in all areas of laboratory medicine including:

• chemistry
• hematology
• immunology
• microbiology
• blood banking

Others specialize in just one of these laboratory disciplines. MLS professionals are found in hospitals, commercial laboratories, blood banks, public health agencies, pharmaceutical research, forensic science and other businesses that generate laboratory data.

MLS professionals are credentialed. They may obtain certification by either of two nationally recognized agencies.

• The American Society for Clinical Pathology offers its Board of Registry (BOR) exam.
  This credential requires a bachelor's degree (4 years) and successful performance on the BOR certification exam. Those certified by the BOR use the professional title of Medical Technologist or MT(ASCP).
• The National Certification Agency for Laboratory Personnel (NCA) also offers certification examination to those holding a bachelor's degree. Those passing the NCA exam use the professional title of Clinical Laboratory Scientist or MLS. MTs or MLSs are experts in medical testing who interact with all members of the healthcare team that rely on accurate and timely results to enhance patient care.
