Urine Glucose Oxidase Test

Definition

The urine glucose oxidase test measures the concentration of glucose in the urine. It involves the use of commercial, plastic-coated, chemically treated strips.

Description

This test is used primarily to monitor urine glucose in people with diabetes mellitus.

Diabetes mellitus (sugar diabetes) is a condition that causes problems in controlling the amount of sugar (glucose) in the blood. It is a common disorder that occurs when the pancreas either totally stops producing insulin or does not produce enough of the hormone for the body's needs.

This lack of insulin results in a low absorption of glucose, both by the body's cells, which need it for energy, and by the liver, which stores it. Another result is an abnormally high level of glucose in the blood, which is then excreted in the urine.

Before Using This Test

In order to get the best results from the test, please be aware of the following:

• There are some foods and medicines that color the urine and may make the test harder to read. Consult your doctor about your current dietary habits and medication regimen.

• There are some medicines and nonprescription products such as vitamins, aspirin and iron that may cause false test results. Consult your doctor.

Proper Use Of The Test

1. Wash and dry your hands before performing the test.

2. Urinate a small amount into the toilet, stop, then continue urinating into the collection container.

3. Collect a urine sample in a clean, dry container. Do not refrigerate the urine or let it stand for more than 30 minutes before testing it.

4. Choose a well-lighted area with a clean, dry working surface to perform the test. Be sure to have a timing device (that measures in seconds) available.

5. Be careful not to touch the testing areas on the strips since skin oils and perspiration may effect the test chemicals and cause a false reading.

6. Read and follow the package directions carefully.

7. For test strips, dip the strip in the urine for 1 to 2 seconds (read package directions for exact time) and tap it on the edge of the container to remove the extra urine.

8. Hold the strip up in the air for exactly the time stated on the package and compare the color of the test strip with the reference color blocks on the label.

9. Record the results.

After recording the results be sure to store the unused kits in a cool place (not the refrigerator), make sure the container is closed tightly to prevent deterioration of the strips and throw away discolored or darkened strips or expired kits.

Test Results

Normal results typically mean no glucose is present in the urine.

If you are taking this test for the first time, an abnormal reading may indicate diabetes, adrenal and thyroid disorders, liver and central nervous system diseases, conditions involving low kidney function, toxic kidney tubular disease, heavy metal poisoning or pregnancy. Please consult your doctor immediately if the results are abnormal.

If you are taking this test as part of your diabetic therapy, please refer to the doctor's guidelines on what to do when your results show that your diabetes is not under control.

In any circumstance, notify your doctor if you are not sure of your test results.
