Turnaround Times

We offer a range of Turnaround Time (TAT) options to meet your project and budgetary requirements. TAT’s vary by test and commodity with some reporting options available by end of next business day, with our most cost effective options ranging from 5 to 8 business days. Please note: that end of next business day options are available upon prior notification and only for certain methods, and samples must be received at the lab before 11AM to ensure timely processing in the lab. TAT’s start from successful receipt of a complete COC upon intake.

Delivery of Certificates of Analysis (COA)

COA’s will be e-mailed as soon as work is completed. You may request a paper copy by mail. If payment must be received prior to release of COS’s unless payment terms have not been established prior to receipt of samples.
