QMS™ Therapeutic Drug Monitoring (TDM) Assays

Accurately measure therapeutic drug levels in serum and plasma with the Thermo Scientific™ QMS™ Therapeutic Drug Monitoring (TDM) Assays. These liquid, ready-to-use assays are a convenient alternative to more expensive and time-consuming technologies. QMS (Quantitative Microsphere System) immunoassays have excellent precision and accuracy, optimized performance on a wide range of general chemistry analyzers and lot-to-lot consistency.

Reduces Labor

• Significantly reduces labor, time, and expense compared to HPLC or LCMS and other technologies
• Based on competitive inhibition immunoassay principle whereby free-drug in the sample competes for antibody binding sites with drug molecules coated onto uniform microparticles

Ready-to-use

• Liquid stable and ready-to-use
• Applicable to general chemistry analyzers
• Validated parameters assure lab-to-lab reproducibility
• Superb reagent stability

Optimal Sensitivity

• Excellent correlation to reference methods
• Optimal sensitivity, precision and dynamic range
• Low cross-reactivity with metabolites and commonly co-administered drugs
• Low interference from endogenous substances
