Rachel is superb at honing in on critical issues that are not always immediately apparent. One of her greatest strengths is her ability to examine a case in-depth and break it down piece by piece to determine what tests might be most valuable, and then to  interpret the lab findings in an overall context, e.g. what a patient’s copper balance is in relation to zinc, rather than just looking at independent values, in order to build a comprehensive picture of a patient’s health or otherwise.
