What is the correct specimen volume required for a typical urinalysis test?

For a typical urinalysis test, the correct specimen volume is generally 30ml. This volume is preferred because it provides an ample amount of urine for the various tests that may be performed, including physical examination, chemical analysis, and microscopy. Adequate volume ensures that there is enough sample for repeat testing or to account for potential variations in urine concentration or constituents.

Collecting 30ml optimally balances the need for sufficient material while minimizing waste. Although smaller volumes can sometimes be utilized in certain scenarios, 30ml is an established standard that ensures the reliability of test results in a clinical context.
