This test checks for abnormally high levels of glucose in the urine. High levels of glucose in the body can be a sign of an underlying health condition. You can develop serious complications if your glucose levels remain high and if it is left untreated. For this test, you need to provide your urine sample. A small cardboard device known as a dipstick will determine your glucose levels. Depending on the amount of glucose in your urine, the dipstick will change colour. Most commonly, elevated glucose levels indicate diabetes. It’s crucial to monitor glucose levels if you are diagnosed with diabetes or have pre-diabetic symptoms such as excessive thirst, blurred vision, and fatigue.
