Glucosuric profile (glucose in urine)
Medical expert of the article
Last reviewed: 05.07.2025
In healthy people, glucose entering the primary urine is almost completely reabsorbed in the renal tubules and is not detected in the urine by conventional methods. When the concentration of glucose in the blood increases above the renal threshold (8.88-9.99 mmol/l), it begins to enter the urine - glucosuria occurs.
Glucose may appear in urine in two cases: with a significant increase in glycemia and with a decrease in the renal glucose threshold (renal diabetes). Very rarely, episodes of moderate glucosuria are possible in healthy people after a significant alimentary load of products with a high carbohydrate content.
Usually, the percentage of glucose in urine is determined, which in itself provides insufficient information, since the amount of diuresis and, accordingly, the true loss of glucose in urine can vary widely. Therefore, it is necessary to calculate daily glucosuria or glucosuria in individual portions of urine.
