Which of the following statements is accurate regarding urine collection procedures?

The statement that all urine samples must be chilled immediately is accurate because chilling urine samples helps to preserve the integrity of the analytes present in the urine. Many substances in urine can degrade or undergo changes if left at room temperature for extended periods. Cooling the sample restricts bacterial growth and enzymatic activity, ensuring that the sample remains representative of the patient's condition at the time of collection.

First morning samples, while often preferred for certain tests due to their concentrated nature, may not require refrigeration immediately but should still be handled properly to avoid alterations. Universal precautions apply to all bodily fluid collections, including urine, to protect both the patient and healthcare workers. Additionally, not all containers are appropriate for urine collection; specific types of sterile or preservative-containing containers are typically recommended to ensure accurate results.
