What are urine samples collected during normal urination called?

Urine samples collected during normal urination are referred to as voided urine specimens. This terminology is used because the process occurs naturally as part of the urination process, without any manipulation or specific preparation required from the patient. Voided specimens are typically used for everyday testing, such as routine urinalysis, because they can provide a general assessment of a person's health and the functioning of their urinary system.

While random urine specimens is a term that can describe urine collected at any time without special considerations, voided urine specimens more accurately indicates that the sample is obtained specifically through the voluntary act of urination. Timed urine specimens involve collecting urine over a specific period, and clean catch urine specimens have particular procedures to reduce contamination during the collection, often for the purpose of accurately diagnosing urinary tract infections. Therefore, the most appropriate term for a urine sample taken during routine urination is voided urine specimens.
