Reagent for optimizing sputum samples

Reagent for optimizing sputum samples

Maintain Mycobacterium tuberculosis (MTb) viability while liquefying and decontaminating sputum samples during transport. Learn more >


OMNIgene®●SPUTUM is a non-toxic and highly stable reagent that liquefies and decontaminates sputum samples at the point-of-collection or in the lab while preserving MTb viability for at least 8 days at ambient temperatures. Optimized samples are compatible with all routine TB tests, enable cost-effective sample transport and simplify laboratory workflows while eliminating the need for NaOH/NALC.

Key Features

  • Stabilize, liquefy and decontaminate samples at point-of-collection
  • Optimize samples for all diagnostic algorithms
  • Eliminate NaOH/NALC to simplify workflows
  • Minimize contamination and cross-contamination


  • Enable sample standardization and improve sample quality
  • MTb bacteria remains viable for at least 8 days at ambient temperature
  • Eliminate cost and complexity of cold chain shipping and storage
  • Simplify sputum processing and batching in the lab
  • Eliminate samples lost due to putrefaction
  • Access and transport more samples at less cost
