** Turnaround times are provided as ranges, and may vary depending on daily testing volumes and specimen type.

*** Test set-up: Samples received by 10:30 AM are eligible for same-day testing. Same-day testing is not guaranteed and may vary based on daily test volume, sample receipt time, testing schedules, and sample type. Some samples may require pretreatment and/or confirmatory testing, which can extend turnaround time (TAT).

**** Patient's identification must be visible on the specimen container.
