A 76-year-old patient with type 1 diabetes received emergency attention after becoming comatose shortly after picking cherries. The first capillary blood glucose measurement collected from a finger showed a concentration higher than the reference limits (Derkenne et al. BMJ Case Reports. 2016). After symptomatic treatment was started, a second blood glucose measurement was taken at the earlobe. It revealed profound hypoglycemia (0.89 mmol/L), which prompted the administration of appropriate treatment. The elevated initial capillary blood glucose measurement was associated with the presence of fructose on the patient’s fingers from picking cherries. After receiving an IV administration of glucose, the patient regained normal consciousness and had no sequelae despite the severity of the hypoglycemia and delayed diagnosis. Pseudohyperglycemia is rare, and delayed diagnosis frequently results in severe sequelae or death. (218-5)
