The same well plates and antibiotics used in reference ASTs are inoculated using positive blood culture without the delay of solid media culturing. After incubating only 3 hours, the well plates are measured using a unique microfluidic sensor that measures individual microbes from each well. This rich data set is then processed using advance AI to produce results as accurate as conventional phenotypic ASTs, but in only 4 ½ hours.
LifeScale’s benchtop form factor uses the same well-plates and antimicrobials of the most relied-upon ASTs, but provides results in just 4½ hours. LifeScale won’t disrupt your lab’s optimized workflow — use it with your rapid blood culture identification system and continue to run most ASTs on your current standard of care.
LifeScale’s throughput and parallel sample processing will support the demands of most hospitals and keep impact on your staff to a minimum with easy sample preparation. It’s cost-effective and convenient, with compact consumables that can be stored at room temperature.
Featuring Population Profiling and AI-Predictor.
LifeScale is the only AST using population profiling of individual cell mass, giving the fastest and most accurate AST results.

We won’t stop with Gram-negative bacteria in positive blood culture. LifeScale’s platform is extensible to the range of phenotypic ASTs for which rapid results can help your patients. Antifungal testing from blood culture, high-value isolates, and other direct-from-sample tests such as acute UTIs and BALs are on the LifeScale roadmap.
