Adnan S Jaran PhD.
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 procedures to ensure that the customer’s requirements are met consistently
Ensuring that staff are trained and provided with the resources to do the job right the first time

QUALITY is ACHIEVED BY:[cont]
Ensuring that all activities are undertaken correctly
Ensuring that when things go wrong, effective corrective action is taken to avoid repetition of errors
Undertaking regular reviews and audits of all processes
Total and organised commitment from management

What is Quality?

Adnan S Jaran PhD.7
Achieving a 99% level of quality
means
accepting a 1% error rate1%
7
Adnan S Jaran PhD.
In France a 1% error rate 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 contaminatedby bacteria
3 bad landings at Orly Paris airport

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.

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

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.
Adnan S Jaran PhD.
Essential to all aspects of health care are laboratory results that are
accurate,
reliable, and
timely

Laboratory Quality Management System
Coordinated activities to direct and control an organization with regard to
quality.
ISO 9000:2000
31
Adnan S Jaran PhD.
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.
