    Background: The measurement of haemoglobin (Hb) concentration provides a reliable, primary screening test for the presence and severity of anaemia. The HemoCue® is a point-of-care test for Hb measurement. The introduction of point-of-care testing in hospitals and general practice has improved patient care and accessibility. This study was performed to evaluate the utility of point-of-care Hb measurement with the HemoCue® device for the diagnosis of anaemia. Method: In this prospective study, we compared the analytical performance of the HemoCue® to the Coulter® LH 750 automated haematology analyser with regard to accuracy, precision and linearity in the measurement of Hb in adult and paediatric patient samples, referred for routine laboratory testing. Results: Samples from 100 patients were analysed with both instruments, and the results were compared using standard scatter and difference plots. The mean Hb value of the HemoCue® (11.3 g/dl; range 4.6-16.7) was comparable to the Coulter® LH 750 (11.3 g/dl; range 4.7-17.2). The Bland-Altman difference plot revealed good correlation. Bias between the two methods was small, and the imprecision was within acceptable limits. Hb measurement was linear in the range of 4.8-20 g/dl. Conclusion: In all age groups, the HemoCue® point-of-care device can be used to provide accurate and reliable Hb measurements with a smaller sample volume, improved turnaround time, and long-term cost saving.Keywords: haemoglobin, HemoCue®, point-of-care testing, anaemia screenin

    Integrated monitoring of water allocation reform in South Africa

    Get PDF
    South Africa faces significant inequities in the allocation of water for productive purposes. Water allocation is one component of a wider government mandate to address the inequities of the past. Water allocation reform is being implemented by the South African Department of Water Affairs and Forestry (DWAF), through the Water Allocation Reform (WAR) Programme. This paper presents an approach for determining indicators that can be used to monitor targets for WAR and for prioritising areas for specific WAR interventions. The approach integrates water use data with environmental, economic and equity data to provide a holistic picture of the progress and benefits of WAR. Limitations of the approach are discussed, specifically related to the data on which the indicators are based. The development of data for the equity indicator presents specific challenges which are discussed through examples from its application in four case study areas.Keywords: monitoring, water allocation reform, equity, indicators, South Afric

    Local reference ranges for full blood count and CD4 lymphocyte count testing

    Objective. Recent advances in full blood count and CD4 technology, coupled with the changing population demographics of the Gauteng region, have necessitated reevaluation of the reference ranges currently in use.Methods. A cross-sectional study of 631 female and 88 male HIV-negative participants from the Gauteng region was performed. Full blood count, automated differential and CD4 count analyses were done using the latest internationally accepted technology. Reference ranges were compiled from the 2.5th and 97.5th percentiles for both male and female participant groups, and gender and ethnic comparisonscalculated by non-parametric tests.Results. Results of 41 females were removed from the statistical analysis because their results were suggestive of possible anaemia. Full blood count reference interval comparison confirmed gender-specific differences in red blood cell and platelet parameters. Ethnic-specific differences were found for some red blood cell parameters in the black female cohort. In addition, black males and females bothgenerally had lower neutrophil and higher lymphocyte counts than a combined Asian/Caucasian/coloured ethnic group.Conclusion. Comparison of the currently calculated referenceranges with published data and reference values in use indicated that a separate ethnic-specific reference range should be introduced for the percentage/absolute neutrophil count and percentage lymphocytes. In addition, locallyerived reference ranges for red cell distribution width(RDW) and CD4 percentage of lymphocytes should be implemented for routine diagnostic testing

    Implementation Dilemma of the Concept ‘Research-Intensive University’ at Institutions of Higher Learning: A Critical Analysis

    Get PDF
    Critical theory is used in trying to understand the concept of research-intensive universities and the moral collapse of teacher training institutions in higher education. What makes critical scholarship different from interpretive scholarship is that it interprets the acts and the symbols of society in order to understand the ways in which various social groups are oppressed. This article is driven by the researchers’ own experiences at institutions of higher learning in South Africa, as well as literature review. Moral reasoning is important within the professions because of the social status of professions. Claims by various groups about fairness of college access are central to the public discourse about equal treatment. The pressure to publish is keenly felt by all education academics, so considerable tension could arise over who is involved in initial teacher training. There is a danger that training quality teachers may be compromised as research-intensive universities will pay more attention to research at the expense of teaching and learning DOI: 10.5901/mjss.2014.v5n27p3
