AbstractBlood smear analysis is a well known technique in medical laboratories. Clinical relevance of this analysis and its interpretation are very important. Consequently, monitoring of laboratory performance by an external quality assessment scheme is strongly recommended. Most starting external quality organizers set up a scheme for clinical chemistry. Due to a lack of guidance documents, many organizers are reluctant to offer a hematology scheme. This article aims to be a very practical guidance document for external quality assessment organizers for the set up of blood smear schemes.

AbstractBlood smear analysis is a well-known technique in medical laboratories. The clinical relevance of this analysis and its interpretation are very important. Consequently, monitoring of laboratory performance by an external quality assessment scheme is strongly recommended. This article represents a very practical guidance document for External Quality Assessment Scheme (EQAS) organizers for setting up blood smear schemes. In the first part of the guidelines, the Hematology Working Group of the European External Committee for External Quality Assurance Programmes in Laboratory Medicine (EQALM) published practical information for the preparation of blood smears for use in an EQAS. Part II focuses on aspects such as survey preparation, statistical evaluation and reporting, and describes particular details for organizing blood morphology EQA surveys by means of virtual microscopy.Clin Chem Lab Med 2006;44:1039–43.

Objective: To determine the affect of autonomy on clinical chemicaltesting in pathology department Quaid-i-Azam Medical College and to assess the change in the attitudes oflaboratorians and physicians Study design: Retrospective and comparative. Duration of study: 1-11-93 to 01-11-03Materials and Methods: A retrospective study was carried out from 1-11-93 to 01-11 03 in which records from 1-11-93to 1-11-03 were collected and evaluated .Separate record of each month’s revenue from clinical chemistry section wascalculated. In order to determine what changes have been brought about after autonomy a universal questionnairewas used to assess the attitudes of physicians and surgeons of hospital inquiring whether they noticed anyimprovement in the efficiency of clinical chemical test results after autonomy. 620 doctors were interviewed throughstructured questionnaire. The questionnaire was designed to assess the knowledge , attitude and practices of doctorstowards autonomy. In order to determine that who is the most beneficent of autonomy ,different records werecollected. and discussions were made with consultants. Results: Autonomy brought about a healthy change in the staffof clinical chemical section. Quality control has improved the morale of lab staff since technical deviations are morereadily identified and corrected within the lab, gross errors are rarely found by the clinicians and so their respect forand confidence in the lab has strengthened Replenishment of chemicals/reagents are timely made. The number ofavailable test has significantly increased which in turn has significantly raised the revenue generated since autonomy is awarded. Pilferage of chemicals has been stopped. Turn around time has been decreased. Clinical Chemical sectionparticipates in External Quality Assessment Scheme, NEQAPP (National External Quality Assessment ProgramPakistan),which is an essential part of the routine of a well –run lab. Patient is the most beneficent since autonomy isawarded to QMC/BVH, BWP. Conclusions: A significant improvement in the efficiency of the analytical performancehas strengthened the faith of laboratorians and physicians in the test results after autonomy

Middle East Region

The establishment and first 7 years' operation of an external quality assessment scheme for clinical chemistry in the Middle East region are described. The scheme utilises specimens distributed previously in the UK, and the performance of participating laboratories is assessed relative to the UK consensus values, taking account of method. Variance Index scoring has been used to quantitate performance, and there has been an improvement in average scores during the operation of the scheme. There are currently 88 participants, though some laboratories which failed to return results regularly were removed from the scheme. The consensus values from the scheme itself have now been validated, and in future the scheme should operate independently.

An external quality-assessment scheme was initiated among a group of 13 clinical chemistry laboratories for the urinary analysis of calcium, chloride, creatinine, glucose, osmolality, phosphate, potassium, protein, sodium, urate and urea and also for the estimation of creatinine clearance. The greatest inter-laboratory imprecision occurred in the assay of urinary protein. The results of the survey are compared with similar schemes elsewhere and their significance discussed.
