Turnaround varies by lab and panel — most offer 48–72 hours standard, with same-day or 24-hour rush service for an added fee. Each listing shows its average TAT.
Most accredited labs test flower, concentrates/oil, and edibles. Check each listing's Quick Facts for the specific sample types they accept.
Compliant labs integrate with METRC or the applicable state track-and-trace system to report results directly against your manifests.
Contact the lab directly to arrange intake — many offer scheduled pickup and have posted sample-intake hours on their profile.
