1. A method for determining an efficacy of a medication for a patient, the method comprising:

  • (A) administering to the patient the medication selected from the group consisting of a statin, an angiotensin enzyme inhibitor, an angiotensin receptor blocker, an antibiotic, an anti-clotting medication, ranolazine, clopidogrel, ticagrelor, prasugrel, aspirin, evolocumab, alirocumab, trastuzumab, adalimumab and etanercept;

    (B) applying a wet run solution to a testing area of a skin surface of the patient, wherein the wet run solution comprises a chemical selected from the group consisting of acetylcholine, bradykinin, adenosine, vasopressin, nitroglycerin, sildenafil, serotonin, and thrombin;

    (C) positioning a color detector on the patient after the application of wet run solution, wherein the color detector is configured for detecting at least a red wavelength light and comprises an input for receiving light, and wherein the input is positioned to receive light from the testing area;

    (D) making and saving a baseline color measurement of the testing area using the color detector, the baseline color measurement comprising a baseline skin redness level of the testing area with the patient resting;

    (E) initiating an exercise protocol after the baseline color measurement, wherein the exercise protocol comprises the patient engaging in a physical exercise;

    (F) making and saving a plurality of exercise color measurements of the testing area at different times during the exercise protocol, the exercise color measurements each comprising skin redness levels measured by the color detector;

    (G) ending the exercise protocol by the patient ending the physical exercise;

    (H) after the exercise protocol ends, beginning a recovery phase, with the patient resting during the recovery phase;

    (I) making and saving a plurality of recovery color measurements of the testing area at different times during the recovery phase, the recovery color measurements each comprising skin redness levels;

    (J) calculating the red shift for the patient, the red shift being calculated by comparing the baseline skin redness level and one of a maximum skin redness level and a minimum skin redness level, the maximum skin redness level or minimum skin redness level being selected from the exercise color measurements and the recovery color measurements; and

    (K) determining that the medication is not efficacious when a negative red shift value is calculated by comparing the baseline skin redness level with the minimum skin redness level to determine that the negative red shift value has occurred.
