Recent input from our customers reports higher-than-expected false positive results when using PDX-LIB for environmental Listeria monitoring. In response, Paradigm Diagnostics has re-formulated the incubation media (PDX-LIB) and launched a comprehensive field trial comparing the original LIB to LIB 2.0 (the re-formulated broth). A preliminary report of the first 100 samples confirms ZERO false positive results and NO Compromise in sensitivity.
