Abstract

Disclosed are diagnostic test strips to screen for azotemia or kidney disease in felines and canines. The diagnostic test strips comprise an elongate carrier material to which is adhered a test pad assembly comprising a reagents substrate material loaded with urease, a pH indicator, and a buffer for adjusting a pH value of a feline or canine saliva sample to within a transition interval of the pH indicator, a laminate layer, and an adhesive layer. The test strips may additionally comprise a control pad assembly adhered to the elongate carrier material adjacent to the test pad assembly.

IPC Classes  ?

• B01L 3/00 - Containers or dishes for laboratory use, e.g. laboratory glasswareDroppers
• C12Q 1/58 - Measuring or testing processes involving enzymes, nucleic acids or microorganismsCompositions thereforProcesses of preparing such compositions involving urea or urease
• G01N 33/84 - Chemical analysis of biological material, e.g. blood, urineTesting involving biospecific ligand binding methodsImmunological testing involving inorganic compounds or pH
• G01N 33/52 - Use of compounds or compositions for colorimetric, spectrophotometric or fluorometric investigation, e.g. use of reagent paper

• G01N 21/80 - Indicating pH value

Abstract

An improved thin film optical interference apparatus, methods of use and of manufacture are provided, the apparatus comprising means for generating optical interference colours directly on the surface of a single layer of anodized metal. The interference colours generated by the presently improved apparatus can be used to indicate the presence of at least one organic compound or analyte.
