Can I refrigerate my urine sample?

It is best to keep it at room temperature, there is no need to refrigerate the sample. It is stable at room temperature for up to 7 days. It is recommended to immediately ship the samples after collection.

According to the attached Urine Test Collection Instructions, for best results, "Mail the package to laboratory as soon as possible via FedEx. Contact Fedex to schedule a pick up at 800-463-3339 if needed." Also, "SHIP WITHIN 12 HOURS OR LESS OF COLLECTION. HOLDING COLLECTED SAMPLES CAN RESULT IN REJECTION."
