The presence of glucose (+) in a urine test is not particularly serious, but a normal person’s urine will not contain glucose. If glucose is present in the urine, the most common reason for a positive urine test is likely to be due to elevated blood sugar, which causes excess sugar to be excreted from the urine. In addition, if there is a kidney disease it can also lead to a lowered renal glucose threshold, so that the renal tubules’ ability to reabsorb glucose is reduced, causing excess glucose to be excreted from the urine, in which case further kidney-related tests need to be improved to clarify the diagnosis. In addition, in women, the renal glucose threshold is also reduced in the case of pregnancy, and glucose may also be present in the urine test. Regardless of the cause of glucose in the urine, it is important to pay attention to it and go to the hospital for relevant tests to clarify the diagnosis and treatment.
