| Abstract | Rapid tests for detecting group A streptococci in throat swabs are often performed outside hospitals or commercial laboratories by individuals with little or no technical training. We compared the abilities of nurses and technologists to perform and interpret three commercial kits (Directigen 1-2-3, ICON Strep A, and Culturette Brand 10-Minute Strep A ID) in three hospital satellite locations (the emergency department, a walk-in emergency clinic, and a general pediatric clinic). When the three tests were compared with culture, the sensitivities of the tests as performed by nurses and technologists, respectively, were 39 versus 44% for Directigen, 55 versus 51% for Culturette, and 72 versus 39% for ICON. A significant difference in sensitivity was found only with ICON tests. This result was largely explained by the tendency of technologists to test moist swabs, while nurses generally processed dry swabs; ICON test sensitivity was significantly greater with dry swabs. The specificities of Directigen and ICON tests performed by nurses and technologists were high (97 to 100%). The difference in the specificities of the Culturette test as determined from results obtained by nurses and technologists (80 versus 98%) was due to the tendency of one nurse to overinterpret the latex agglutination reaction. Analysis of the accuracies of the tests during practice periods compared with the accuracies of the tests during the study periods revealed statistically significant improvement in test performance. We conclude that these tests are specific but not sensitive when performed by nurses and technologists in satellite laboratories. With one exception, nurses and technologists performed the tests with comparable accuracy after brief training periods. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
