Midstream urine specimen

A collection method requiring perineal care where the labia are spread to expose the urethral area on a female and urine is collected after the stream has started.

24-hour urine specimen protocol

A collection that must be re-started if a void is missed or if the person is incontinent during the duration of the test.

Urine glucose testing

Testing performed on urine to check for the presence of sugar.

Reagent strips
