1. A health monitoring system, comprising: a computing system configured to interact with a first diagnostic test associated with a first diaper, the first diagnostic test having one or more sensors configured to produce a first at least quasi-quantitative indication of a first set of one or more analytes contained in a first portion of bodily waste excreted by a subject in a first interval of time; the computing system having one or more processors, a memory, and a health monitoring system program including a plurality of instructions stored in the memory that are executed by the one or more processors to instruct a data acquisition device to acquire automatically one or more digital images of the first at least quasi-quantitative indication, the one or more digital images not including a color comparison scale, to determine and select automatically by the one or more processors a focused first digital image from the acquired one or more digital images of the first at least quasi-quantitative indication, and to analyze the first digital image by comparing data derived from the first digital image of the first at least quasi-quantitative indication to a cluster, in the memory, the cluster based in part on different levels of brightness of the first digital image, in order to produce a first data point corresponding to the first at least quasi-quantitative indication; the computing system being further configured to interact with a second diagnostic test associated with a second diaper, the second diagnostic test having one or more sensors configured to produce a second at least quasi-quantitative indication of a second set of one or more analytes contained in a second portion of bodily waste excreted by the subject in a second interval of time; and wherein the plurality of instructions stored in the memory are also executed by the one or more processors to instruct the data acquisition device to acquire automatically one or more digital images of the second at least quasi-quantitative indication, to determine and select automatically by the one or more processors a focused second digital image from the acquired one or more digital images of the second at least quasi-quantitative indication, and to analyze the second digital image to produce a second data point based on the second at least quasi-quantitative indication, and to send a notification to a user if both the first and second data points correspond to an abnormal health condition of the subject.
