MicroPhage tests deliver breakpoint antibiotic susceptibility/resistance results. To do this, two slightly different bacterial identification reactions are conducted in parallel within the same test. The first reaction utilizes BAT™ technology to identify the bacteria. The second reaction is identical except that it contains the antibiotic of interest at an established concentration or “breakpoint.” If bacterial growth is inhibited in the parallel reaction, the bacteria are determined to be susceptible to the antibiotic. If not, they are determined to be resistant.The process is simple – mix the clinical sample with the proprietary reagents in both the Identification (ID) and the Resistance (RS) tubes provided in the test kit and incubate. The bacteriophages infect the target bacteria, replicate, and are detected. When the bacteria are present (ID is positive), the RS result reports susceptibility to antibiotics.
