Final answer:
Glucose in urine can indicate hyperglycemia, a symptom of diabetes mellitus, and is detected through tests such as the Benedict's test.
Step-by-step explanation:
The substance in urine that may indicate hyperglycemia is glucose. Hyperglycemia is a condition characterized by high blood sugar levels, which often occurs in individuals with diabetes mellitus. When the blood glucose levels are too high, the kidneys are unable to reabsorb all of the glucose, leading to its excretion in the urine, a condition known as glycosuria. Diagnostic tests like Benedict's test can be used to detect the presence and amount of glucose in urine, which is a straightforward test that can even be performed at home to monitor sugar levels.
Review of Other Options:
- Bilirubin in urine may indicate liver problems.
- Protein, such as albumin, in urine can indicate kidney damage.
- Urea is a normal component of urine and not specifically linked to hyperglycemia.
