To be processed by the miR Scientific lab, urine specimens need to be maintained between -10°C to 8°C (>14°F to <46.4°F) with no more than a single freeze-to-thaw cycle from the time they have been produced by the patient until they have been received at the lab. Without the ability to freeze the provided Collection Kit’s gel packs, the specimen’s temperature integrity will not be ensured, and it is likely that the specimen will be rejected by the miR Scientific laboratory.
