Systems And Methods For Semi-Quantitative And Quantitative Detection Of Metabolities Of Progesterone

A test system comprising:

• a test device including a test area, a results area, and a control area, wherein the test area of the body includes a lateral flow assay that detects the presence of a target analyte in a target substance, wherein, in response to exposure to the target analyte, the results area produces a visually identifiable test-line having a test-line color density and a visually identifiable control-line having a control-line density, wherein the visually identifiable test-line increases in darkness according to an increased concentration level of the target analyte;
• and
• a user device including a camera, a processor, a display, and memory storing program instructions, wherein, in response to executing the program instructions, the processor:
• receives an image of the test area from the camera, the image including the visually identifiable test-line and the visually identifiable control-line;
• determines a test-line value defined as a numerical value of the test-line color density;
• determines a control-line value defined as a numerical value of the control-line color density;
• calculates a T/C ratio defined as a relative value of the test-line value to the control-line value;
• and
• determines a quantitative hormone level based on the comparison between the T/C ratio and a data structure that maps calibrated T/C ratios to quantitative hormone levels.
