For persons over 25 years of age, both blood-sugar and urine-sugar determinations were done as initial screening procedures. A screening procedure is a. Correlation Between Plasma and Urine Glucose in Diabetes . Blood sugar versus urine sugar: as observed in patients treated with protamine. Since all these patients were receiving insulin and were, with one exception, young, In the accompanying table a brief summary of the blood sugar findings in this group of What's the Connection Between Hyperglycemia and Diabetes?.

There are no clear-cut boundaries between the normal range of blood sugar and high or low blood sugar. Normal range between hyperglycemia and hypoglycemia Measuring sugar in your urine yourself You can also measure your sugar levels in your urine on your own.

Having sugar in your urine is usually a sign of very high blood sugar levels. In order to measure the amount of sugar in your urine, you need a urine test strip dipstick and a container for collecting urine. It is important to talk with your doctor about the best time of day to do the urine test, and whether to do it before or after eating. When measuring sugar in your urine yourself, you need a sample of urine that has not been in your bladder for long.

Instead, it is more typical to urinate and collect a sample about an hour after the last time you went to the toilet. The test strip is then dipped into the sample. After about two minutes the color pads on the test strip show the results.

To find out what the results mean, the colors on the test strip are compared with the color chart on the package. If the colors on the test strip do not change, you do not have sugar in your urine. The more the color changes, the more sugar there is in your urine, and therefore in your blood. But it is not possible to find out exact blood sugar levels using urine tests.

They can only determine whether you have very high blood sugar.

Measuring blood sugar levels in a laboratory Blood sugar levels can be measured a lot more accurately by taking a blood sample from a vein and having it tested in a laboratory. A special kind of test called a glucose tolerance test also involves taking blood samples — in this case, to see how the body deals with larger amounts of sugar.

Most people with diabetes have the HbA1c levels in their blood measured regularly. Your HbA1c value is a measure of how high your blood sugar levels have been on average over the last eight to twelve weeks.

This is an indication of how well-controlled your blood sugar is and whether your diabetes treatment might need to be adjusted.

Additional option for monitoring glucose levels Devices that measure the amount of sugar in fat tissue underneath your skin offer another way to continuously monitor sugar levels. This is called continuous glucose monitoring CGM. CGM devices measure the amount of sugar in the fat tissue every few minutes, and alert you if the levels are too high or too low.

CGM devices are also available in combination with an insulin pump. People who have type 1 diabetes can improve the regulation of their blood sugar levels by monitoring the sugar levels in their tissue.

The suitability of any of the described options in an individual case can be determined by talking to a doctor. Also note down any special circumstances at the time of the test, for example, if you were unwell, were under emotional stress, had changed the amount or type of food you were eating or were taking medicine to treat another condition.

Limitations of urine glucose monitoring Monitoring diabetes control by testing urine glucose levels is rarely recommended, due to the limitations of this method.

These limitations include the following. Urine glucose tests do not reflect your blood glucose level at the time of testing; instead, they only give an indication of blood glucose levels over the previous several hours. For example, some of the urine present in your bladder may be 2 hours old, and may show glucose even though your blood glucose level may have normalised since then.

Compare this to a blood glucose test which gives you a reading of your blood glucose level at that moment. So, a negative urine glucose test may be the result of a normal blood glucose level or a dangerously low blood glucose level hypoglycaemiawith the urine glucose test unable to differentiate between the 2 situations. The results of urine glucose tests are influenced by the volume and concentration of urine that you pass, which will vary with the amount of fluid you consume and your fluid loss due to such things as heavy sweating or vomiting.

■Why Does Diabetes Cause Frequent Urination

Urine glucose tests that are designed for home use rely on interpreting a colour change to define the result. Subtle colour differences may be difficult to interpret. If a urine glucose test is not read at the specified time after exposing the test strip to the urine, then the result is prone to error. Some medications mayinterfere with the results of urine glucose testing.

Advantages of urine glucose monitoring There are a couple of advantages of urine glucose monitoring. It is less painful than blood glucose monitoring — no finger pricks to collect blood samples for testing. Urine test strips may be less costly than buying a blood glucose monitor and its test strips.
