A random blood glucose of 6.5 mmol/L in the afternoon is usually normal.
Random blood glucose is the value of glucose in the blood measured by drawing venous blood or collecting peripheral blood from the finger or other parts of the body at any one time, and is one of the important indicators of glucose metabolism disorders.
Diabetes mellitus can be diagnosed by the presence of the typical symptoms of “three excesses and one deficiency” (excessive drinking, urination, food intake, and weight loss) and a random venous plasma glucose of ≥11.1 mmol/L.
If the random blood glucose value is abnormal or suspected to have diabetes-related symptoms, it is recommended to go to the hospital, under the guidance of professional doctors to clarify the condition and standardize the treatment.
