Samples may be dropped off Monday through Thursday between 9:00 AM and 5:00 PM or by appointment outside these times.

Walk-in visits are accepted; however, we encourage customers to call ahead when possible to help answer any questions regarding testing. A brief advance notice allows our staff to provide helpful guidance and sampling information that may help avoid the need for resampling. Prior to visiting the laboratory, customers can review detailed sample collection instructions by following the provided link to ensure proper handling and compliance.
