The Use of Direct Susceptibility Tests from BACTEC 9240 to Microscan Walkaway

Summary

Using a straight-from-the-bottle into-the-instrument technique, a series of direct susceptibility tests were performed with the BACTEC 9240 and Microscan Walkaway systems. Although rapid, unacceptably high error rates were obtained when compared with a standardized method. This procedure is not sufficiently accurate for clinical use.
