A number of tests may be performed by dipping a chemical analysis strip into a cup of urine and reading the color coded patches against the references on the strip bottle.
Specific gravity is the weight of a liquid compared with an equal volume of water.
Water is represented by 1.000. Normal range is 1.010-1.030. A higher concentration is a sign of dehydration. PH is the measure of hydrogen ions in solutions. O is neutral and has a PH of 7.
