Role of laboratory service in patient care is well recognized in developed compared to developing countries like Ethiopia where most medical decisions are based on clinical judgment. Laboratory based medical decisions save life and resources. Thus, health facilities (HFs) having capacitated laboratories provide better health care service. Thus, this study assessed capacity of laboratories found in all nine HFs in zone one of Afar region, Ethiopia. Cross-sectional study was conducted from January to May 2015. Data were collected using questioner from medical laboratory professionals (MLPs) and using cheek list from laboratory registration books. Collected data was analyzed using SPSS. Availability of laboratory related national guidelines and standard operating procedure varies among HFs studied. In 42 selected laboratory equipment and materials assessed, their availability shows variations among HFs from 13 (30.2%) to 32 (74.4%). Among different laboratory tests recommended to be performed at health center (HC) level by World Health Organization (WHO), six tests were not performed in all HC laboratories. Moreover, 11 (31.4%) MLPs received in-service training in the past one year. Internal quality control measures were done in 3 (33.3%) laboratories. However, all laboratories were involved in external quality assurance with varied schedules. Specimens after testing and specimen with prolonged transit time were discarded using standard rejection criteria in 8 (88.9%) and 3 (33.3) laboratories, respectively. Study showed that laboratories assessed have good capacities in involving external quality assurance and having proper laboratory test request format. But capacity of laboratories assessed is limited and unsatisfactory in number of laboratory tests performed at HC laboratories, in internal quality control measure implementation, and in getting up-to-date in-service training to staff. Thus, to enhance capacity of laboratories in HC, responsible bodies shall avail basic laboratory materials and equipment, make fair distribution of MLPs, provide up-to-date training, and implement internal quality control measures in laboratories.

Abstract Internal Quality Control and External Quality Assurance are separate but related processes that have developed independently in laboratory medicine over many years. They have different sample frequencies, statistical interpretations and immediacy. Both processes have evolved absorbing new understandings of the concept of laboratory error, sample material matrix and assay capability. However, we do not believe at the coalface that either process has led to much improvement in patient outcomes recently. It is the increasing reliability and automation of analytical platforms along with improved stability of reagents that has reduced systematic and random error, which in turn has minimised the risk of running less frequent IQC. We suggest that it is time to rethink the role of both these processes and unite them into a single approach using an Average of Normals model supported by more frequent External Quality Assurance samples. This new paradigm may lead to less confusion for laboratory staff and quicker responses to and identification of out of control situations.
