3. QUALITY is ACHIEVED BY:
Determining the customer’s precise requirements
Ensuring that all resources, facilities and skills required
to meet the customer’s requirements are available
Planning, documenting and implementing management

effective corrective action is taken to
avoid repetition of errors
Undertaking regular reviews and audits
of all processes
Total and organised commitment from
management

would mean everyday
14 minutes without water or electricity
50,000 parcels lost by postal services
22 newborns falling from
midwives’ hands
600,000 lunches contaminated
by bacteria
3 bad landings at Orly Paris airport

12. Quality Management System Definition
Coordinated activities to direct and
control an organization with regard
to quality (ISO,CLSI).
All aspects of the laboratory operation
need to be addressed to assure
quality; this constitutes
a quality management system.
Adnan S Jaran PhD.

13. QUALITY CONTROL
Every analysis in the lab. generates a result
The validity of that result cannot be taken for
granted, however, without some body of
supporting evidence.
The most convincing evidence is the
establishment of a rigorous comprehensive
Quality control program that is faithfully followed
This is the only way to guard against the possible
deterioration of an analytic system, to become
altered to imprecision of results when they occur,
and have confidence in test result when
everything is in control

14. QUALITY CONTROL
A comprehensive quality control (QC) program
consist of all the means used by a laboratory to
ensure the reliability of every assay performed
on specimens arriving in the lab.
The program includes much more than the
analysis of a control serum with every run, and
it involves: (1) lab. Director, (2) Technologists,
(3) all other personnel who are an integral part
of the specimen collecting, and
(4) The analytical system.

32. Key Messages
A laboratory is a complex system and
all aspects must function properly to
achieve quality.
Approaches to implementation will vary
with local situation.
Start with the easiest, implement in
stepwise process.
Ultimately, all quality management
system elements must be addressed.
