How reliable are commercial urine self-tests? “Absolutely unnecessary for anyone who just eats and drinks”

He does an extra test: “I created a second account under the name Kris – my brother, so to speak,” he winks. “And I took the test twice in quick succession. In general, the results were in line. But for sodium I had a 4 out of 10, my invented brother Kris got a 6 with the same pipi. With magnesium it was the other way around: there the score was 10 out of 10 in one test, and 8 out of 10 in the other, each time with identical urine.”
