For a patient with an HgbA1c of 8.4% and glucose in urine, which lab finding would be expected?

In the context of a patient with an HbA1c of 8.4% and glucose present in the urine, the expected laboratory finding is an elevated C-peptide level. This scenario suggests that the patient has poor glycemic control, indicated by the elevated HbA1c, which reflects average blood glucose levels over the previous 2-3 months.

The presence of glucose in the urine (glucosuria) indicates that the blood glucose levels have exceeded the renal threshold (approximately 180 mg/dL), leading to the spillover of glucose into the urine. In cases where the pancreatic beta cells are functioning and producing insulin in response to high blood glucose, elevated C-peptide levels would be observed. C-peptide is a byproduct of insulin production, and high levels mean that there is an adequate or increased production of insulin by the pancreas.

The other options, while they relate to the metabolic state of the patient, do not align as directly with the lab findings and clinical picture provided. In particular, low blood glucose levels would not be expected given the high HbA1c and glucosuria, which are indicative of persistent hyperglycemia. High insulin levels may not necessarily be present if the beta cells are becoming exhausted or if
