Test device for albumin

Abstract

Abstract A TESTING DEVICE FOR THE DETECTION OF ALBUMIN IN URINE IN THE FORM OF A CARRIER, SUCH AS A PLASTIC SHEET MATERIAL, WHICH HAS HAD APPLIED THEREOVER A LAYER OF PARTICULATE HYDROPHILIC ABSORPTIVE MATERIAL, A PORTION OF WHICH HAS BEEN FIRST IMPREGNATED WITH A SOLUTION OF AN INDICATOR WHICH EXHIBITS PROTEIN ERROR AND THEN DRIED, AND A SECOND PORTION OF PARTICULATE MATERIAL WHICH HAS BEEN IMPREGNATED WITH A SOLUTION OF A BUFFER COMPOUND FOR MAINTAINING THE URINE WITH WHICH THE DEVICE IS TO COME IN CONTACT AT A PH WHICH IS WITHIN OR BELOW THE RANGE THROUGH WHICH THE INDICATOR CHANGES COLOR DUE TO A CHANGE IN PH. THE DEVICE MAY ALSO COMPRISE A CARRIER WHICH HAS HAD APPLIED THEREON A LAYER COMPOSED OF AGGLOMERATES OF PARTICULATE HYDROPHILIC ABSORPTIVE MATERIAL, SUCH AS ALUMINUM OXIDE, SILICA GEL, CELLULOSE, EXFOLIATED VERMICULITE OR THE LIKE, WHICH AGGLOMERATES HAVE BEEN FORMED BY FIRST COMPRESSING INTO A COMPACTED FORM A MIXTURE OF THE SAID PARTICULATE MATERIAL WHICH HAS BEEN PREPARED BY FIRST IMPREGNATING ONE PORTION OF IT WITH A SOLUTION OF INDICATOR WHICH EXHIBITS PROTEIN ERR AND THEN DRIED, AND A SECOND PORTION WITH A SOLUTION OF A BUFFER AND THEREAFTER PARTICULATING THE COMPACTED FORM SO AS TO FORM AGGLOMERATES COMPOSED OF THE TWO KINDS OF DISCRETE PARTICLES OF THE HYDROPHILIC ABSORPTIVE MATERIAL AND THE INDICATOR AND BUFFER WITH WHICH SAID PARTICLES HAVE BEEN IMPREGNATED.
