As a medical laboratory technician, you may or may not choose to become nationally certified. However, some organizations may require you to be registered or eligible for registration before being hired or soon after being offered the position. Some nationally recognized certification agencies include the American Society for Clinical Pathology (ASCP), the American Medical Technologists (AMT), and the National Credentialing Agency for Laboratory Personnel (NCA). These agencies provide certification programs that showcase an individual's competence and expertise in medical laboratory technology. Let the interviewer know where you are in the registration process and your plans for registration if you have not already done so.
