Elecsys® Immunosuppressive Drug Assay Panel

Trusted and consistent results for organ transplant patients
Elecsys Immunosuppressive Drug Assay Panel

Trusted and consistent results for organ transplant patients

Optimal immunosuppressive therapy, ­defined clinically and by therapeutic drug monitoring (TDM), is essential to prevent acute rejection and ensure long-term survival of both the patient and the allograft. Characterized by a narrow therapeutic window, the use of immunosuppressive drugs (ISDs) requires both precise and consistent measurement of their concentration in whole blood during life-long monitoring.1

 

Consolidation for optimized workflow

 

The full ISD menu available on one automated and integrated Roche SWA platform:

  • Best-in-class automated MPA (Mycophenolic Acid) available on cobas c modules2
  • Elecsys Cyclosporine and Tacolimus now completed with Sirolimus and Everolimus on cobas e modules

One universal pre-treatment procedure for all ISD assays increase efficiency, ensure high quality results for every product and reduce handling errors in the lab

Outstanding possibilities for consolidation with >230 parameters on one cobas® platform

 

High precision for confidence in results

 

  • High precision at low drug concentrations and across a wide measuring range
  • Excellent performance confirmed in routine customer laboratories3

 

Consistent results for life-long monitoring

 

  • Excellent lot-to-lot comparability and traceability
  • Consistent patient results across all cobas® platforms due to universal reagent concept
  • Low variability across different customer labs proven in external quality schemes3
  • High comparability to well established and validated LC-MS/MS
