For 40 years, Syva has been one of the industry’s leading developers and producers of drug testing products and services.

• In 1971, Syva introduced FRAT (Free Radical Assay Technique) to address growing substance abuse challenges. FRAT was the first non-radioimmunoassay system.
• In 1972, a less complex system, EMIT^® (Enzyme Multiplied Immunoassay Technique) was introduced. EMIT^® provided a stable foundation for the rapid expansion of drug monitoring. It remains widely recognized as a flexible, high quality technology for drug monitoring.
