Parasitic infections continue to take their toll on HIV positive patients by influencing the blood qualitatively and quantitatively. The objective of this study was to determine the prevalence of intestinal parasitic infections in relation to anaemia and CD4 counts among HIV-infected patients in Benin City, Nigeria. Using a serial sampling method, a total of 2000 HIV-infected patients were recr...

The limits of accuracy for the quantitation of anti-D using the AutoAnalyzer have been reduced from +/- 26% with manually prepared dilutions to +/- 14% using an automatic pipette, as expressed by the 95% confidence limits. The error inherent in the AutoAnalyzer was estimated to contribute +/- 10% to the overall error. Problems associated with the reproducibility of this method for anti-D quanti...

Methodological modifications have been made in our “SMA 12/60 AutoAnalyzer” system, to improve the reproducibility and accuracy of six commonly performed procedures. These include glucose with the glucose oxidase method, albumin with the bromcresol green method, and alkaline phosphatase with the sodium thymolphthalein monophosphate method. We have also modified the composition of the reagents u...

A method for the Reiter protein complement-fixation test using the Techncon AutoAnalyzer is described. Two hundred and fifty sera were tested, when six false-positive and nine false-negative results were obtained when compared with results obtained by the manual method. Deep freezing the sera before testing on the AutoAnalyzer increased the sensitivity so that in a further 250 sera tested no fa...

BACKGROUND The speed and quality of information have become essential items in the release of laboratory reports. The Sysmex(®)SP1000-I device has been developed to prepare and stain smear slides. However, for a device to be cleared for use in the laboratory routine it must pass through a validation process. OBJECTIVE To evaluate the performance and reliability of the Sysmex(®) SP-1000i slide...

− 1 − Leukocyte classification on Sysmex XE series hematology analyzers involves staining leukocytes with proprietory Polymethine Dye reagents that have affinity for nucleic acids. The outputs are two-dimensional scatter diagrams of side scatter and fluorescence intensity (DIFF scattergrams) subsequent to flow cytometric analysis of the stained cells. Leukocyte classification is based on the lo...
