The control system described here is used to monitor the performance of urinary reagent-strip tests for leukocytes.. The presence of leukocyte esterase in the urine is used as a marker for leukocytes in urine.. The control system is based on sonicated leukocytes, isolated from whole blood.. The esterase activity of this sonicate is determined by spectrophotometry with the N-tosyl-L-alanine determine the amount of sonicate needed to prepare buffered esterase-containing at room temperature.. The variability of the control system was tested by preparing it five times in a day on five separate days..

Commercial test strips using the protein error of certain indicators for the colorimetric detection of protein (especially albumin) were compared with a quantitative nephelometric method.. The study proved that there is good agreement between the results from the quantitative method and those from the test strips separation of the segments for semi-quantitative determinations.. There was a very good agreement between the test strips in protein-containing urines.. In proportion of false-positive results.. Berger W.. Kuse R, Hausmann K.. By a simple program of quality control for the Coulter counter model S two deficient reagents could be detected.. To high values of PCV associated with a decrease of MCHC were caused by a faulty Isoton batch..

A portable reflectance photometer and dry-reagent strips were used to measure total bilirubin, glucose, creatinine, creatine-kinase and urea in equine, bovine and canine sera.. peroxidase uses following aspects of performance are reported: within run variation determined on animal samples, between run variation using a commercial control serum, correlation between dry-reagent and wet-reagent methodology on clinical samples.. Results of the above analytes have shown a satisfactory precision and indicate an excellent correlation with the reference method of our laboratory..

Production of an anticanine globulin (polyspecific) reagent for laboratory investigation.. University, Chiang Mai, Thailand.. OBJECTIVES: Canine allo- or autoantibodies are clinically important, but attachment of these immunoglobulin G (IgG) antibodies does not produce observable haemagglutination.. Antibody to canine globulins is required to demonstrate sensitisation of red blood cells.. Commercial reagents are available, but these often differ in sensitivity and specificity.. Rabbit anticanine globulins (polyspecific) were produced for use in canine blood compatibility testing and in the investigation of immune-mediated haemolytic anaemia.. METHODS: Canine sera was pooled, IgG was purified and subsequently used to immunise rabbits.. A rising titre of anticanine IgG was demonstrated by indirect enzyme-linked immunosorbent assay.. Rabbit anticanine complement was isolated and investigated by agglutination of complement-coated canine red blood cells.. Both antibodies were purified and checked for crossreactivity before being combined to polyspecific anticanine globulins.. The obtained reagent was used to indicate sensitised canine red blood cells and free antibodies in three different types of clinical samples, including blood for compatibility testing and that for investigation of immune-mediated haemolytic anaemia and screening for post-transfusion alloantibodies and was also compared to commercial Coombs' reagent.. RESULTS: The product provided results in accordance with those from commercial CLINICAL SIGNIFICANCE: This product is helpful for canine crossmatching purposes and in the investigation of immune-mediated haemolytic anaemia.. group IIA cations.. reagent for the qualitative identification of alkali metal (Group IA) and alkaline earth (Group IIA) cations.. This methodology was based on the characterization of observed crystal morphologies, since a unique crystal habit could be associated with each adduct product.. To understand the scientific foundations which permitted chemical microscopy to function as a useful analytical technique, the products formed between dilituric acid and the Group IA and IIA cations were characterized using polarizing optical microscopy, powder X-ray diffraction, thermal analysis and solid-state nuclear magnetic resonance.. It was found that the origins of the different crystal morphologies associated with each of the adduct arose from the ability of the systems to form various hydrate species, which could also contain structural variations due to cation/diliturate packing patterns..
