The BacterioScan 216Dx System is a semi-automated, in vitro diagnostic system (consisting of an instrument, software, and disposable Multicuvettes) that analyzes light scattering to measure any bacterial growth directly from urine sample incubated in trypticase soy broth. The BacterioScan 216Dx is for qualitative determination (presumptive positive or presumptive negative) of bacteriuria at a density of ≥5x104 CFU/mL. The BacterioScan 216Dx results are intended for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of Urinary Tract Infections (UTIs). The 216Dx System is not intended to provide bacteriuria levels, bacterial identification, or differentiation. The system does not distinguish between growth of infecting, colonizing or contaminating bacteria, or if mixed urogenital flora are present. Presumptive positive urine samples must be cultured. Presumptive negative urine samples must be cultured if a low level of bacteriuria is suspected and is clinically relevant. The system also does not detect anaerobic bacteria, fungi/yeasts, fastidious organisms or those associated with sterile pyuria.

The BacterioScan 216Dx is for qualitative determination (presumptive positive or presumptive negative) of bacteriuria at a density of ≥5x104 CFU/mL. The BacterioScan 216Dx results are intended for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of Urinary Tract Infections (UTIs). The BacterioScan 216Dx System uses laser light scattering to measure turbidity (particle density) of a prepared urine-broth sample during a period of incubation. The system is designed to kinetically capture digital measurements of sample turbidity at very low particle densities. Classification software analyzes these optical signal measurements, and interprets increasing turbidity as bacterial growth. Samples with robust growth during the second half of the test cycle, and/or high turbidity, are reported as "Presumptive Positive" for bacteriuria and/or UTI. Low turbidity samples that do not exhibit growth are classified as "Presumptive Negative". The user logs into the 216Dx interface and is prompted to associate a patient sample ID with a Multicuvette serial number and well location. The user will then pipette the prepared liquid samples into a Multicuvette. Once the Multicuvette is filled, it is loaded into a 216Dx Instrument. The Multicuvette is then incubated for approximately three (3) hours. During the instrument run, the 216Dx appliance will analyze optical measurements to provide a qualitative determination of the presence or absence of viable bacteria in urine specimens at a cut-off of >5x10 CFU/ml. The Classification algorithm qualitatively assesses a result by analyzing periodic measurements taken throughout this incubation period.
