I buy the 10LG Parameter Urine Reagent Strips that can detect a few abnormalities by dipping the strip into a sample of urine, Leukocytes, Nitrite, Urobilinogen, Protein, pH, Blood, Specific Gravity, Ketone, Bilirubin,
Glucose. There is a coloured
chart on the container that you compare your urine strip test to after waiting for the appropriate amount of time as indicated on the container.
