Urine specimens should not remain unrefrigerated for longer than two hours. Aurine specimen that cannot be delivered to a laboratory within two hours should be stored in a refrigerator. The reason for this precaution is that urinesamples undergo chemical changes at room temperature.
Allow the test, urine specimen and/or controls to reach room temperature (15-30â) prior to testing. 1. Bring the pouch to room temperature before opening it. Remove the test device from. the sealed pouch and use it as soon as possible. 2. Place the test device on a clean and level surface.
