Controlled (U.S. Schedule 5 to Schedule 1) and non-controlled samples are used. Each test involves the qualitative analysis of two samples - one or both could be a controlled substance. Samples in Test 5002 are different from those in Test 5001.

U.S. laboratories must provide a DEA registration number; enrollment will not be processed without it.

International laboratories will be notified via e-mail of the actual drug, quantity to be shipped, and the deadline for receiving the appropriate paperwork. Therefore, you must provide CTS with a reliable and secure e-mail address for a contact within your laboratory who will NOT be doing the testing. CTS will then request: 1) an original import permit, if required by your country; and 2) an original signed statement from the laboratory indicating that the drug samples will be used for scientific purposes only and will not be re-exported from the country of destination. CTS cannot ship your Drug Analysis order without receiving both of those items.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.

Samples ship in August.

Enrollment deadline: 15 March 2025
