Samples spoil if not received and tested promptly (I.e., eColi). I asked for a lab closeted to my address and was provided a shipping label for one across the county. Took a week from shipping for them to register the sample as “received,” with an ETA a week after that. Won’t be able to trust the results so I will likely retest again, locally. Don’t believe the many labs all over the country map as the ones closest to me were not selected as requested.
