The level of glucose, fructosamine (FA), glucosylated hemoglobin (HbA1) was determined for 21 patients with cerebral haemorrhage at an early stage of their illness. The correct level of FA and HbA1 shows that in the period of 2-3 weeks and 2-3 months before the stroke the average level of glucose in blood was normal. No significant differences of glucose concentration with respect to patients with a good prognosis and patients with a bad prognosis were found.
