Q&A column, 4/15
April 2015—Why is the number 12 for lymph node retrieval in colon cancer protocol reporting not specific to the kind of resected specimens and whether a total colectomy was performed? We are establishing a list of maximum allowable dilutions for our clinical chemistry analytes. Are you aware of any reference that would list absurd or invalid values for such analytes, i.e. the endpoint that would determine the most dilutions we would have to do for the highest possible value for that analyte?
