  4. Invert the specimen 3-4 times.
  5. Label the plastic transport tube with the patient name, patient identification number, date & time of collection and the initials of the nurse who collected the specimen.

Storage:

  1. Urine not in transport tubes: 4 hours at room temperature, 4 days refrigerated.
  2. Urine in Xpert Transport Tube: 14 days at room temperature, 28 days refrigerated.
