How to Read the urinometer
4.) Reading the multistix.
Note – Do not let the multistix touch the chart itself while reading it
Possible Multistix Positives
Benedict’s – tests for the presence of a monosaccharide (reducing sugar) or in our bodies case glucose. The solution will turn from blue to brick red in the presence of glucose.
Biuret – Tests for the presence of protein in solution. In the presence of protein the solution will turn from blue to violet in color.
Sulfur – will test for the presence of bile in the urine. If the pinch of sulfur floats in the urine then there is no bile present. If the sulfur sinks and becomes frothy then there is bile present in the urine.
