You're pushing the edge of the storage window for refrigerated urine. It is good for 2 weeks in the frig but since its Friday it might not be until Monday before they get to testing it and they might not store it in the frig themselves because they know if it is fresh it can go the weekend without being refrigerated. I would have only gone 1 week in the frig and longer gone to the freezer, which is 1 year storage.
