Based on this, the provider switches the antibiotic therapy to a drug to which the isolate is susceptible. The American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines have clearly defined intra-tumor heterogeneity of HER2 amplification (i.e., HER2/CEP17 signal ratios >2.2 in 5%-50% of the neoplastic cells).

Published validation studies: Average # evaluators = 8 individuals/ study (range, 3 - 26 persons). It is estimated that each year, thousands of patients become colonized by drug resistant organisms, and using outdated clinical breakpoints comes with the risk of mismanaging those patients. Fitzgibbons PL, Bradley LA, Fatheree LA, et al. Updates to this guideline are important as IHC testing is an essential component of the pathologic evaluation of many specimens, and the results increasingly provide key information that helps determine how patients are treated. Now imagine the patients health worsens, and they are moved to another hospital to receive the care they need.
