INS and Hypoglycemia: A critical sample collected during hypoglycemia demonstrated elevated insulin levels (up to 62 μIU/mL, normal range: 2.6-24.9 μIU/mL) and C-peptide concentrations (3.1 nmol/L, normal range: 0.37-1.47 nmol/L), with suppressed ketone levels (0.1 mmol/L, normal range: 0.0-0.6 mmol/L).
