Diabetes is a clinical syndrome caused by factors such as absolute or relative lack of insulin in the body, abnormal secretion time, and disorder or resistance of the insulin acting body. If diabetes is not well controlled, it may cause some acute complications, such as hypoglycemia, ketoacidosis, and non-ketone hyperosmolar coma. Serious long-term complications include cardiovascular disease, chronic renal failure, retinopathy, neuropathy, and microvascular disease. For diabetic patients, it is very important to monitor blood sugar from time to time. The primary goal of managing diabetes is to maintain a normal blood sugar level. If the patient can pay attention to blood sugar control, it may be able to effectively prevent the complications.
Before measuring the blood glucose concentration value, a blood collection step must be performed.
