H1 generally refers to the HI of the glucose meter, an abbreviation for HIGH, which indicates that the patient’s blood sugar is too high.
All blood glucose meters have a relatively fixed range with an upper limit for blood glucose. The presence of a HI during a blood glucose test using a glucose meter suggests that the blood glucose is too high, usually exceeding the monitoring range of the meter, and the patient’s blood glucose cannot be monitored using the meter alone, which can be considered a critical value.
When blood glucose is too high, acute complications such as diabetic ketoacidosis or diabetic hyperosmolar hyperglycemia syndrome are likely to occur, and the condition can be life-threatening in serious cases. It is recommended to go to the hospital immediately when the above situation occurs, to draw venous blood for blood glucose examination, to complete the blood gas analysis and other related examinations, and to carry out rehydration, insulin glucose lowering, and other related treatments under the guidance of the doctor.
In case of abnormal blood glucose value, it is recommended to go to the hospital for consultation and treatment under doctor’s guidance.
