1. A health monitoring system, comprising: a computing system having a processor, a memory, and a health monitoring system program including a plurality of instructions stored in the memory that are executed by the processor to: receive and store a first digital data packet that includes a first sample reading, collected at a first time interval, of a first diagnostic test of a first diaper configured to detect an analyte in bodily waste excreted by a subject, wherein the first sample reading includes data corresponding to an amount of the analyte detected in the first diagnostic test and the first time interval at which the first sample was collected; receive and store a second digital data packet that includes a second sample reading, collected at a second time interval different from the first time interval, of a second diagnostic test of either the first diaper or a different diaper configured to detect the analyte, wherein the second sample reading includes data corresponding to an amount of the analyte detected and the second time interval at which the second sample was collected; automatically compare the first and second sample readings against a standard for the analyte that indicates normal and abnormal levels of the detected analyte over different time intervals to analyze whether the first and second data readings correspond to an abnormal health condition of the subject based on the amount of the analyte detected in the first and second sample readings collected at the first and second time intervals; and automatically transmit an indication if there is an abnormal level of detected analyte based on analyzing the first and second sample readings.
