Can this result diagnose a condition on its own?

No. Urinalysis findings are interpreted with symptoms, collection conditions, medical history and related tests.

Which reference range should I use?

Use the performing laboratory's own reference interval and reporting method first.

When should I discuss the result with a healthcare professional?

Clearly abnormal, persistent, symptomatic or unexpected findings should be reviewed by a healthcare professional.

Reference and clinical context

Start with the performing laboratory's reference interval, method, collection conditions and reporting unit. Urinalysis findings do not establish a diagnosis on their own.
