Step-by-step explanation:
False. Second voided and 2-hour postprandial urine tests are not used in patients with diabetes. These tests are more commonly used in patients with diabetes insipidus or diabetes mellitus, which are indicated by symptoms such as frequent urination, increased thirst, and increased hunger. In diabetes mellitus, simple urine tests like Benedict's test can be used to check for the presence and quantity of glucose in the urine. Glucose tolerance tests (GTT) are also conducted in patients suspected with diabetes mellitus.
