Fasting blood glucose of 5.85 mmol/L is considered normal for the general population.

Under normal circumstances, the normal range for fasting blood glucose is usually between 3.9 and 6.1 mmol/L. A fasting blood glucose level of 5.85 mmol/L falls within this range and therefore indicates no abnormality. However, a fasting blood glucose level of 5.85 mmol/L is near the upper limit of the normal range. Although it does not meet the diagnostic criteria for prediabetes or diabetes, blood glucose values approaching the upper limit may suggest the presence of hidden glucose metabolism abnormalities. It is recommended to monitor blood glucose regularly and to comprehensively assess the situation by combining measurements such as 2-hour postprandial blood glucose and glycated hemoglobin (HbA1c). Additionally, for pregnant women, a special population, the criteria for fasting blood glucose are stricter, typically required to be between 3.1 and 5.1 mmol/L. If a pregnant woman's fasting blood glucose reaches or exceeds 5.8 mmol/L, there should be increased vigilance for the possibility of gestational diabetes.

At the same time, maintaining a healthy lifestyle in daily life, such as balanced nutrition and appropriate exercise, can help maintain stable blood glucose levels.
