Following the agreement on mutual cooperation between EFLM and W. de Gruyter for Clinical Chemistry and Laboratory Medicine journal (CCLM), it has been planned to send regularly to the EFLM contacts the table of contents of CCLM issues and the list of future titles as well. I do hope you will appreciate the initiative which is intended as a further service by EFLM to our European professional community. CCLM is published on a monthly basis and is the most relevant Journal on Clinical Chemistry in Europe; it is a valuable and updated source of knowledge for the professionals in the field, well recognized all over the world. The CCLM 2014 Impact factor is 2.707.
With kindest regards,
Chair EFLM Communication Committee

The estimate of measurement uncertainty
EFLM webinar held on May 10 by Ilenia Infusino, BSc.
For those who were not able to join the EFLM webinar on 10 May or for those attendants who want to recall presented ideas, we are happy to inform you that the recording of the EFLM webinar on “The estimate of measurement uncertainty” is now available:
The importance of good pipetting techniques for the proper measurement of CD4/CD8 for the management of patients with HIV necessitates regular assessment of pipetting techniques, accuracy and precision checks
Integrity of pipettes and good pipetting techniques are critical for accurate and reproducible results.
Pipette accuracy and precision checks should be peformed monthly and when indicated as part of troubleshooting corrective actions.
Pipetting techniques of new staff should be validated before the staff are certified to process patient samples.
Most techniques for pipette accuracy and precision checks are complex and require sophisticated analytical balances and extra laboratory space.
The Flow Cytometry Centre recommends a technique that does not require analytical balances .
The major advantage of the technique is that it does not require additional equipment and space.
Flow cytometers and pipettes already in use in the flow cytometry laboratory is all that is required.
The technique is peformed using cheap commercial low, medium and high fluorescent beads and 3 or 4 colour CD4/CD8 protocols (CDC/NIH 1998/2008 guidelines).
Pipetting technique, accuracy, precision and performance of single platform 3 and 4 colour protocols can all be assessed using this technique.
Fluorescent low, medium, and high beads are added to normal blood prepared for CD4/CD8 analysis as per CDC/NIH abbreviated 3 or 4 colour panels and analysed on a 3 or 4 colour flow cytometer.
The expected bead counts are compared to actual counts and the results are statistically analysed to aseess accuracy.
CD4 and CD8 counts of the normal blood are used to assess precision.
Pipetting technique, accuracy and precision should be checked monthly.
A simple, user friendly method that is compatible with flow cyometers currently in use at most reference and central hospitals in Zimbabwe can be easily utilized.
Provincial and district hospitals can regularly refer their pipettes to the nearest central or reference laboratory for precision and accuracy checks.
Details of the procedure and training are available from: Flow Cytometry Centre, suite 12A, 1st floor, Medical Centre, 52 Baines Avenue, Harare.

ROAD TOWARDS ACCREDITATION by Mrs. E. Chidziva
Challenges facing laboratories worldwide are to provide QUALITY services which include reliable and accurate medical results timeously. Resources are often limited hence the need to use them as efficiently and effectively as possible.
The Zimbabwe government reiterated the need to provide its citizens with quality medical services by strengthening evidence based medicine. One way to achieve this was through ISO 15189 accreditation for medical laboratories. Accreditation is a procedure by which an authoritative body gives formal recognition that an organization is compliant and competent to carry out specific tasks according to predetermined standards. This recognition puts us on the international map because test results that are produced at Cimas Medical Laboratories are acceptable worldwide reducing the need for medical tourism.
Road leading to accreditation
An initiative was rolled out by the government in collaboration with ZINQAP, CDC, WHO-AFRO where the SLMTA/SLIPTA program was unveiled. Strengthening Laboratory Management Towards Accreditation is a management tool that allows laboratories to progressively improve on their quality management system through a five tier rating system as they work towards ISO 15189 accreditation.
Stepwise Laboratory Improvement Processes Towards Accreditation is a framework to encourage, support and recognize the implementation of Quality Management System in medical laboratories in a stepwise manner.
Progression towards ISO 15189 accreditation
- It was important to get buy in from management and staff. Initially this proved difficult because change is never easy and always is painful.
- A quality steering committee was formed with a representative from each department chosen by staff members so as to get buy in from staff by actively involving them.
- The committee then drew up a plan of activities which included internal audits and structured meetings.
- Training requirements were identified and trainings were carried out.
- All support staff participated in the accreditation process even though they were not directly involved.
- Cimas Medical Laboratories management was totally committed. The Managing Director being the champion of accreditation was astute in identifying skills in his staff which resulted in persons being given tasks aligned to their skills in an effort to utilize talent towards achieving Accreditation.
ACCREDITATION IS AN INDICATION THAT QUALITY IS A WAY OF LIFE
