3.Product feature and application


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 40mg/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 metabolicallyimprobable.

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.

ProteinThis test is based on the color change of the indicator tetrabromophenol blue. A positiveeaction 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.


How To Test?

1. Remove one strip from the bottle and replace the cap immediately.

2. Immerse the reagent area of the strip in the urine specimen and take it out quickly.

3. Wipe off excess urine against the rim of the specimen container.

4. Read the test results carefully within 60 seconds in a good light and with the test area held near the appropriate color chart on the bottle label. Changes in color that appear only along the edges of the test pads or after moving than 2 minutes have passed are of no diagnostic significance. Results with leukocytes test portion can be read within 120 seconds.

If reading instrumentally, carefully follow the directions given in the appropriate instrument operating manual
