Features & Benefits

Methaqualone is a sedative-hypnotic drug that is usually taken orally. This was once a prescribed treatment for insomnia and anxiety and is now a highly addictive and Schedule I controlled illegal substance. The EMIT II Plus Methaqualone Assay detects methaqualone and methaqualone metabolites, and also the pharmaceutically similar drug mecloqualone.

The EMIT II Plus Methaqualone Assay provides:

  • Good specificity for methaqualone and metabolites
  • Excellent precision—all within-lab (total) CVs ≤0.7% or less across the assay range
  • Ready-to-use liquid reagents, calibrators, and controls
  • 98% correlation to reference method (GC/MS)

Applications are available for the Viva-Jr®, Viva-E®, Viva-ProE®, V-Twin® drug testing systems; AU® Series analyzers; Dimension® Integrated Chemistry Systems; and Dimension Vista® Intelligent Lab Systems.
