MELE case studies

The Medical Laboratory Evaluation (MELE) is a multiple-choice examination used to assess the knowledge and problem-solving skills expected of a medical laboratory professional. Candidates typically encounter it as part of a certification or competency pathway for technologists, technicians, and other laboratory personnel who want independent evidence that they can handle the breadth of routine and specialized testing. The exam is organized around the major laboratory disciplines: blood banking and immunohematology, clinical chemistry, hematology, microbiology, immunology and serology, urinalysis and body fluids, laboratory operations and quality management, molecular diagnostics, and laboratory safety. Questions tend to test practical judgment rather than isolated recall, so expect scenarios involving discrepant results, quality control failures, specimen integrity, and method selection. The MELE case studies are 5 cases and about 2,545 words.
