Yes. you can refrigerate the sample until just before you head to the vet to drop it off. Just let them know that when you collected it and that you had it refrigerated. A sample that cannot be analyzed right away should be refrigerated and can be for up to 24 hours. If it sit unrefrigerated for more than an hour then I would suggest collecting a new sample and refrigerate it right away.
