§493.1445 Standard: Laboratory director responsibilities
The laboratory director is responsible for the overall operation and administration
of the laboratory, including the employment of personnel who are competent to
perform test procedures, record and report test results promptly, accurately and
proficiently, and for assuring compliance with the applicable regulations.
Interpretive Guidelines §493.1445
The requirement that a laboratory must be under the direction of a qualified person is not
automatically met simply because the director meets the education and experience
requirements. It must be demonstrated that the individual is, in fact, providing effective
direction over the operation of the laboratory.
In determining whether the director responsibilities are met, consider deficiencies found
in other conditions, e.g., facility administration, general laboratory systems, preanalytic
systems, analytic systems, postanalytic systems, and proficiency testing.
If the laboratory has more than one person qualifying as a director, one individual must
be designated as accepting ultimate responsibility for the overall operation and
administration of the laboratory. These responsibilities must be delegated in writing.
(a) The laboratory director, if qualified, may perform the duties of the technical
supervisor, clinical consultant, general supervisor, and testing personnel, or delegate
these responsibilities to personnel meeting the qualifications under §§493.1447,
493.1453, 493.1459, and 493.1487, respectively.
Interpretive Guidelines §493.1445(a)
An individual qualified as laboratory director under §493.1443 may not qualify as
technical supervisor in a particular specialty or subspecialty unless he or she has the
required training or experience. If the director of high complexity testing is not qualified
to perform the duties of the technical supervisor or clinical consultant, he or she must
employ individual(s) meeting the respective qualifications.
(b) If the laboratory director reapportions performance of his or her
responsibilities, he or she remains responsible for ensuring that all duties are
properly performed.
Interpretive Guidelines §493.1445(b)
The laboratory director may reapportion to a technical supervisor, in writing, the
responsibilities in: §§493.1445(e)(3), (4), (5), (6), (7), (12), (13), and (14).
The laboratory director may reapportion to a clinical consultant, in writing, the
responsibilities in: §§493.1445(e)(8) and (9).
The only responsibilities that may be delegated to the general supervisor are listed at
§§493.1463(b)(1)-(4).
