  • Publication number: 20060263902
    Abstract: Biological fluid samples are deposited by methods that produce a uniform layer of the sample over a reagent-containing surface. In one embodiment, a nozzle having multiple openings is used to deposit a sample over the reagent-containing surface simultaneously. In an alternative embodiment, single droplets of the sample are deposited in a pattern on the surface, preferably in a sequence of parallel lines. The reaction between the biological sample and the reagents is read from a spectrographic image of the reagent-containing surface obtained by optical methods.

  • Publication number: 20060141546
    Abstract: A method for measuring the bacteria content of fluids such as urine and blood, in which a glycoprotein or glycopeptide is attached to the bacteria and a label attached to or inherent to the glycoprotein or glycopeptide provides a means for determining the amount of bacteria present. A preferred glycoprotein is alkaline phosphatase, which is an enzyme capable of attaching to all bacteria present in the fluid sample and inherently includes a label moiety in that color can be developed by addition of known reagents.

  • Publication number: 20050106748
    Abstract: A method of applying an organic acid reagent having limited transolubility in organic solvents, aqueous solvents, and mixtures thereof to a component of a diagnostic test device by mixing an organic acid reagent and an amine to form a salt complex, dissolving the salt complex in a solvent to release the organic acid reagent into the solvent, and applying the solvent to the component of the diagnostic test device such that the organic acid reagent present in the solvent becomes integrated into the diagnostic test device. The amine is represented by the formula HmNRn wherein m is 0, 1, or 2; n is 1, 2, or 3; the sum of m and n is 3; and R is an independently selected group which renders the salt complex soluble in aqueous solvents, organic solvents, or mixtures thereof. The amine is also represented by the formula NR4+ wherein R is an independently selected group which renders the salt complex soluble in aqueous solvents, organic solvents, or mixtures thereof.
