Urinalysis for Diabetes: Procedure & Results

Measuring sugar level in blood consistently is the basic requirement of living healthy with diabetes. If you are a diabetic injecting insulin, it is important to take readings yourself and track the patterns. An important aspect related to this is measuring the amount of sugar in your urine. If glucose is present in your urine it is a sign of extremely high sugar levels in blood which is removed by the kidneys.

Diabetes Urine Test

Contrary to the blood sugar test for measuring sugar level in blood, a diabetic can conduct this urine test using urine test strip and a container for collecting urine. However before conducting the test to check glucose levels, it is advisable to consult your doctor to know the best time of the day to take sample, which means assessing whether to do it before meals or after meals.

The urine test for diabetics requires a sample which hasn’t been in your bladder for long. Overnight samples are a strict no-no as they are bound to give distorted readings. Before collecting the sample, one must ensure to clean the genital area as urine is highly sensitive for bacteria formation. Once the sample is collected, the test strip is inserted in it and the colour of the strip gives the result.

Who Should Get a Diabetes Urine Test?

In simple terms, those keen to control diabetes must undertake regular tests. It is advisable to know blood sugar normal range in order to assess when the levels go higher than normal.
Urine tests in diabetes are done to check both sugar and ketones in the urine, unlike tests done to check glucose level in blood. Even if either of the two is present, it means that enough insulin is not being produced. Urine ketone testing is most often necessary in people with type 1 diabetes who have glucose level in blood of over 300 mg/dl, who are sick, or who have symptoms of diabetic ketoacidosis, an acute complication of diabetes.

What to Expect During a Urine Test?

Test at Doctor’s Clinic

  • Although the doctor will explain the steps to be taken for the test, the following points briefly explain the process:
    A plastic bottle will be given to collect sample.
  • While you urinate into the cup, in order to avoid contamination with bacteria or cells in your skin, you should only collect the middle part of the urine that comes out (midstream, also called a “clean catch”). The first and last part of the urine can go into the toilet.
  • Place the lid on the cup and wash your hands.
  • Leave the bottle at the designated place.
  • The sample will then be analyzed for the presence of glucose and ketones. The results should be ready shortly after the sample is given.

Test at Home Using Strips

The strips used for at home sugar test are available at the local chemist shop and are coated with chemicals that react with ketones. Once the strip is inserted into the urine sample, the excess urine must be shaken off the strip and one must wait for it to change colour to display the result. The strip then must be compared with the colour chart to assess the amount of ketones present in urine.

Analyzing the Results of Urine Tests

The results of urine tests are measured by referring to the colour chart and matching the colour with that of the strips. In absence of sugar in your urine, the colour on the strips won’t change. Colour of the strip will change based on the level of sugar present in urine. Urine tests are useful for detecting very high blood sugar levels and hence must be discussed immediately with your doctor.

Glucose in blood generally spikes post meals and during the early morning hours. Monitoring blood sugar levels in diabetes on a daily basis using a glucometer is essential as it gives you information about the rise in blood sugars and impact of your dietary and lifestyle changes.
