When is a urinalysis typically performed?

A urinalysis is commonly performed during a maternity visit or complete physical exam because it serves as a valuable tool in assessing overall health as well as identifying potential complications in pregnancy. In maternity care, it can detect abnormalities such as the presence of protein or glucose, which may indicate conditions like preeclampsia or gestational diabetes. For a complete physical exam, a urinalysis helps establish a baseline of patient health and can uncover underlying issues that may not be immediately apparent through other assessments.

While urinalysis can be part of an athletic physical exam, it is not typically a routine requirement, making it less common than during maternity visits or comprehensive check-ups. The suggestion that a urinalysis is done only if symptoms present is also limiting; routine screenings are meant to catch issues early. Lastly, while annual check-ups can include a urinalysis, it is not guaranteed for every patient or situation, hence it's not the best answer. Thus, the timing of urinalysis during maternity visits or complete physical exams is the most appropriate scenario among the options presented.
