A Medical Laboratory Technician (MLT) or Medical Laboratory Technologist (MLT) is a healthcare professional who performs tests and analyses on patient samples like blood, urine, and tissue. They play a vital role in diagnosing diseases, monitoring treatments, and providing essential data to assist doctors in patient care. They operate laboratory equipment, ensure accurate test results, and maintain safety and quality standards in clinical labs. Technologists typically have advanced training and may take on more specialized roles compared to technicians.
