even in cases of suspected type 2 diabetes, ketonuria at the time of diagnosis should be a prompt for hospital assessment (1)
ketonuria is prevalent in untreated adults with apparent Type 2 diabetes presenting acutely (2)
severity of ketonuria in Type 2 diabetes might indicate vulnerability to ketoacidosis
in this study higher hemoglobin A1c, low HDL-cholesterol, younger age, and a past history of alcohol or illicit drug use were associated with ketonuria in Type 2 diabetes
occasionally older patients will present and there will be diagnostic concern whether the patient is really a type 1 diabetic and be requiring insulin treatment from diagnosis
patients with type 2 diabetes who have latent autoimmune diabetes of adulthood (LADA) also may require insulin treatment as an early treatment option. These patients are also more likely to respond to an insulin secretogogue rather the traditional first line therapy of metformin
