Participants will conduct a qualitative analysis of two samples and determine whether a controlled substance is present.

Sample Description: Two items, each containing either controlled (U.S. Schedule 5 to Schedule 1) or non-controlled substances. One or both samples may be a controlled substance.

On-Demand samples are randomized, and each test may contain a different combination of samples. Results can be returned to CTS until 30 June of the following year for which a test was purchased (e.g. a test purchased for 2025 will have a due date of 30 June 2026). Upon submission, an Individual Report will be automatically logged to the Individual Report Library and provided to the primary contact on file via email.

Samples for current-year tests ship within five business days after payment is received and processed. Tests for next year will ship at the beginning of that year or within five business days after payment is received and processed, whichever date is later.

Additional Information: This test is only available to laboratories within the USA. Laboratories in the USA must provide a DEA registration number; enrollment will not be processed without one. Please contact CTS directly via email if you require a large quantity of tests.

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