MATCHING TEST RESULTS TO INVOICES
Lengthy sample descriptions on test results are cut to 30 characters on invoices. To match invoices to test results, locate the Order Number and Sample IDs on each.
Sample IDs on Invoices include: company initials, date of testing, and test number. Example: Sample ID: TLI-091619-947 was tested at Trelfa Labs, Inc. on September 16, 2019. The last digits are the unique identifying number for that particular analysis, which can be matched to test results.
We make every effort to further identify samples as needed. In the case of dairy testing, we include the month tested in the sample description. Example: Vanilla Soft Serve – Jan
