摘要： The invention provides a bicarbonate-containing, crosslinker-free reagent composition which reverses and/or reduces sample handling effects, such as aeration-induced shrinkage and storage-induced swelling of cells in a whole blood sample, particularly for a blood sample requiring repeated sampling and/or subjected to long-term storage. The reagent composition serves as a diluent medium for a blood sample, or an aliquot or portion thereof. The pH of the reagent is in the range of about 7.2 to about 7.5, preferably 7.3. The stability of the pH 7.2-7.5 bicarbonate-containing reagent over time is maintained by storing the reagent in a flexible collapsible container which is impermeable to carbon dioxide and is comprised of a multilayered flexible material, preferably plastic, and attachable to a hematology analyzer.

摘要： The invention describes an improved stable reagent composition and method for the determination of hemoglobin (Hb) using whole blood samples and automated hematology analyzers. The Hb reagent contains an inorganic cyanide salt, at least one surfactant and a base and has a final pH of about 10.0 to about 11.2, preferably about 10.4 to about 11.2 or less and more preferably about 10.8 to about 11.2 or less. This reagent is intended for use as a universal Hb determination reagent for all of the instruments in the aforementioned series and will provide accurate and precise results without accompanying interference from elevated numbers of white blood cells, especially as found in abnormal blood specimens, and without system-to-system variation in the results obtained.

摘要： The present invention provides a heretofore unknown use for a aqueous reagent composition that serves as a universal rinse for performing and/or improving a variety of hematological analyses on automated analyzers. The universal rinse reagent comprises a phosphate buffer to maintain the rinse solution pH at from about 7.0 to about 7.6; a nonhemolytic nonionic surfactant, such as a Pluronic.RTM. an alkali metal salt, such as NaCi; antimicrobial and anti-oxidant compounds; and has an osmolality of about 285 to 305 mOsmol/kg. The universal rinse reagent composition is highly suitable for use in the rinse phases or cycles of all types of blood cell analysis methods and processes performed on semi- and fully-automated systems. The invention allows the replacement of mutiple and specific rinse solutions with the disclosed universal rinse to obtain accurate and acceptable results, independent of the types of blood cell analyses that are performed. The universal rinse is most particularly useful for automated systems having intricate hardware and a number of different input and output channels. The universal rinse composition serves to economize, streamline, and simplify the design and operation of such systems.

摘要： The invention provides a new method and system for detecting and monitoring extracellular or exogenously added hemoglobin, i.e., a cell-free hemoglobin substitute or derivative, in a blood, plasma, or serum sample of an individual, particularly a whole blood sample. The invention further describes the use of automated hematology analyzers to determine and quantify at the same time the concentration of total, cellular and exogenous hemoglobin in a blood, plasma, or serum sample, and is particularly advantageous for medical use during or after patient trauma or surgery, as well as for monitoring hemoglobin levels during patient recovery.

摘要： A novel method and reagent useful therein are cyanide-free and capable of providing a rapid indication, e.g., less than 30 seconds, of total hemoglobin in a blood sample, so as to find particular application in automated hematological instrumentation. The novel reagent comprises an ionic surfactant, a pH of at least about 11.3 and is free of ionic cyanide. The ionic surfactant itself can impart the required pH or a strong base independent of such surfactant may be included.
