Typical adult reference range

Ranges vary between laboratories and methods — compare your result with the range printed on your own report.

What a high or low result can mean

High urine culture: growth of a single organism in significant quantity can be seen in urinary tract infection.

These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.

Good to know

Mixed growth often suggests contamination during collection; clean-catch technique reduces this.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
