MT(AAB), ELS(AAB), ALS(AAB), MDxT(AAB) and MLT(AAB) Credentials
The AAB Board of Registry recognizes individuals at five levels within the clinical laboratory field:
The primary difference between the MT(AAB), ELS(AAB), ALS(AAB), MDxT(AAB) and MLT(AAB) certifications is one of responsibility and supervisory capabilities in the laboratory. The MT(AAB) (medical technologist) performs tests, including high complexity procedures, with a minimum of supervision. An MT(AAB) may supervise MLT(AAB)s (medical laboratory technicians).
MLT(AAB)s perform waived and moderately complex clinical laboratory procedures under the supervision of a laboratory director, supervisor, or MT(AAB).
