Abstract

Abstract A DISPOSABLE TEST PACKAGE COMPRISING A UNITARY MEMBER FORMED INTO A PLURALITY OF COMPARTMENTS FOR THE ADMIXING AND REACTION OF REAGENTS AND SAMPLE MATERIAL ADDED THERETO, AND A PLURALITY OF REAGENT STORAGE CHAMBERS ASSOCIATED WITH EACH REACTION COMPARTMENT BUT NOT ADAPTED FOR DIRECT COMMUNICATION THEREWITH; AND MEANS OVERLYING SAID UNITARY MEMBER FOR PREVENTING THE PREMATURE DISPENSING OF PREPACKAGED REAGENTS FROM THEIR STORAGE LOCATIONS PRIOR TO THE TIME OF ANALYSIS AND FOR MAINTAINING THE PROPER ENVIROMENT WITH THE STORAGE NECESSARY TO PROLONG THE STORAGE LIFE OF PREPACKAGED REAGENTS. SINCE THE REAGENT STORAGE CHAMBERS CANNOT BE PLACED IN DIRECT COMMUNICATION WITH THE REACTION COMPARTMENTS, MEANS EXTERNAL TO THE DISPOSABLE TEST PACKAGE ARE PROVIDED TO WITHDRAW THE PREPACKAGED REGENT FROM ITS STORAGE CHAMBER AND TO TRANSFER SAID REGENT TO ONE OR MORE OF THE REACTION COMPARTMENTS AND/OR ANOTHER REGENT STORAGE CHAMBER. AFTER INCUBATION, EACH REACTION COMPARTMENT IS UTILIZED AS A CUVETTE FOR OPTICAL ANALYSIS, WITHOUT REMOVAL OF THE REACTION MIXTURE THEREFROM.
