1. A method of producing a COVID-19 infection result status of a subject utilizing a urine sample, the method comprising:
contacting a first urine sample with an ion detecting probe to obtain a first sodium ion concentration and a first potassium ion concentration;
contacting a second urine sample with the ion detecting probe to obtain second sodium ion concentration and a second potassium ion concentration;
producing a COVID-19 status by comparing the second sodium ion concentration and the second potassium ion concentration to respective first sodium ion concentration and first potassium ion concentration, wherein a positive COVID-19 status is produced when the second sodium ion concentration is lower than the first sodium ion concentration and the second potassium ion concentration is higher than the first potassium ion concentration and wherein the first sodium ion concentration ranges from 40 mEq/L to 220 mEq/L and the first potassium ion concentration ranges from 25 mEq/L to 125 mEq/L.
