2. What is IQAS
Inter-laboratory Quality Assessment
Surveys; a program enables a laboratory
to compare its performance against
other laboratories and assure the
accuracy and reliability of test results it
provides.

3. Purpose of IQAS
Powerful tool to identify the problems with
methods/equipments, ensure the effectiveness of the training
of new staff and be used in evaluating staff performance.
To satisfy national accreditation; Central Board for
Accreditation of Healthcare Institutions (CBAHI)
To be preparatory phase for laboratories that will go for
international Accreditation

4. IQAS Processes
Samples Preparation;
Distributes samples on the regular schedule;
The participants analyze the tests and report results
to the IQAS provider;
The results are subjected to statistical analysis
based on ISO 13528 standards using robust mean
and standard deviation;
The participants are received their evaluation

6. 2010 : Split samples between two Al Borg Branches
HCV Jeddah Dammam Machine Grade
IMH-01 Negative Negative Axsym Acceptable
IMH-02 Positive Positive Axsym Acceptable
HIV Jeddah Dammam Machine Grade
IMH-01 Positive Positive Axsym Acceptable
IMH-02 Negative Negative Axsym Acceptable

7. 2011
 Start with one pool for specific tests , run between
Al Borg Branches
 Evaluation based on standard deviation index (SDI)
SDI = (R-M)/SD
R = Participant result
M = Target mean value
SD = Standard deviation for peer group

16. Plan of 2014
Increase number of participants
Standardized the program (sample
preparation, statistical calculations,…..) with
full support of GSO
Increase number of samples in each round
Introducing surveys covering tests not in a
formal proficiency testing programs

17. Plan of 2014
√ Increase number of participants … 60 participants
√ Standardized the program with full support of GSO
With the help of GSO, we cooperate with one of expert in
the field of statistical treatment of PT to upgrade our
system to conform to ISO/IEC 17043.
√ Increase number of samples in each round
Increase number of chemistry samples to be 3 instead of 2
samples per round and planning to be 4 per round

18. Signing of Memorandum of Understanding

19. Looking for
Introducing Educational
Activities
Introducing Surveys for tests not
covered by formal PT program
