Regardless of whether you use Urinap or Mocuś, the rules for storing a urine sample are similar: It's best to deliver the sample to the laboratory as soon as possible after collection. If immediate delivery is not possible, the sample can be stored in a refrigerator (2-8°C) for up to 24 hours. Urinap offers a sterile urine container that may better protect the sample from contamination than the container provided in the Mocuś kit. Always follow the laboratory or doctor's recommendations regarding sample storage and transport.
