How to use
Glucose
This test is based on a sequential enzyme reaction. First, glucose oxidase catalyzes the
formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. A second
enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide
chromogen to oxidize the chromogen to colors ranging from blue through greenish-brown, and
brown to dark-brown.
Reactivity of the test decreases as the specific gravity and/or pH of urine increases, and may also
vary with temperature. Ascorbic acid (more than 50 mg/dl) and ketone bodies (more than 40
mg/dl) may cause a false negative result for a specimen containing a small amount of glucose
(100 mg/dl).
However, the combinations of such ketone levels and low glucose levels are metabolically
improbable.
Specific Gravity
This test is based on the pka change of certain pretreated polyelectrolytes in relation to the
ionic concentration. In the presence of an indicator, the color changes from deep blue in urine
of low ionic concentration.
Elevated specific gravity readings may be obtained in the presence of moderate quantities (100-
700 mg/dl) of protein. Specific gravity is also increased with the glucose concentration in the urine
and highly buffered alkaline urines may also cause low reading results.
pH
This test is based on double indicators (methyl red and bromothymol blue), which give a broad
range of colors covering the entire urinary pH range. Colors range from orange through greenish-
yellow and green to blue.
This test indicates the pH values within the range of 5 to 8.5.
Certain drugs, such as those used for hypertension and heart diseases (acetazolamides) may
cause an alkaline urine. Excessive urine on the test strip may wash the acid buffer from the
neighboring protein reagent onto the pH area and change the pH reading to an acid pH although
the urine being tested may originally have been neutral or alkaline. An accurate reading may be
influenced by slight variations of pigments in the urine.
Protein
This test is based on the color change of the indicator tetrabromophenol blue. A positive
reaction is indicated by a color change from yellow through green and then to greenish-blue.
The minimum sensitivity of this test is 10 mg/dl of protein in urine. Highly buffered alkaline urines
(pH 8.5) may give false negative results. The interpretation of results is also difficult in turbid
urine specimens.
