SCT is a government laboratory in Mexico that tests all public transport employees for drug abuse. With a large throughput of samples, the laboratory required a system that was robust and reliable.

In 2005, Randox Toxicology installed the Evidence analyser to ensure that high throughput was met with optimum laboratory workflow. A custom Biochip Array was created for the laboratory, incorporating analytes from DoA I and DoA II, in order to routinely screen the required panel of drugs. 

In 2008, the laboratory manager acquired a second Evidence analyser in order to further expand their testing capacity.
