Testing Urine In The 1940's and 1950's

I was diagnosed in 1945, when I was 6. My father tested my urine every morning. That was the only test done each day. There was never any testing of my blood at home for many years. Benedict's solution was placed in a test tube and 8 drops of urine were added. The tube was placed into a tin can containing about 1.5 inches of water. The can was placed on a burner on the stove and the water was boiled. The tube was then removed from the can and the color was observed. The diagram below shows the possible colors that might have been seen. The original color of the Benedict's solution was blue. If the color was still blue after the boiling, then there was 0% sugar in the urine. If green-0.5% sugar; yellow-1% sugar; orange-1.5% sugar; brick red-2 % or more sugar.
