What is the minimum volume required for a urine specimen collection?

The minimum volume required for a urine specimen collection is generally 15 mL. This quantity is sufficient to perform a variety of tests, including urinalysis and culture, which may require a specific volume to ensure accuracy and reliability of results. A 15 mL sample allows for adequate screening for various substances, including proteins, glucose, ketones, and bacteria, among others. It is important to have enough volume to facilitate proper laboratory processing, as smaller amounts may not provide reliable test outcomes. Additionally, this volume helps to accommodate any potential dilution factors that may occur during specific tests, ensuring that the results are reflective of the patient's actual urinary composition.
