Incorrect diagnostic information. The article “Diabetes Mellitus: Screening and Diagnosis” (January 15, 2016, p. 103) contained incorrect information regarding diagnostic testing for diabetes. The first paragraph of the “Diagnostic Testing” section (p. 106) should have read as follows: “The diagnosis of diabetes can be made when classic signs and symptoms of hyperglycemia are associated with a single random plasma glucose measurement of 200 mg per dL (11.1 mmol per L) or greater. Alternatively, the diagnosis can be made with an A1C level of 6.5% or greater, a fasting plasma glucose level of 126 mg per dL (7.0 mmol per L) or greater, or a two-hour plasma glucose level of 200 mg per dL or greater during an oral glucose tolerance test with 75-g glucose load (Table 217); however, testing should be repeated on a subsequent day to confirm the diagnosis.1,17 If testing results do not match the clinical picture or are inconsistent, repeat testing or testing with another modality may be helpful.17” These changes affected Question 2 in the January 15, 2016, issue of the CME Quiz. The question has been deleted from the online assessment to avoid confusion. The online version of the article has been corrected.
