Capillary blood glucose: which is, like measuring it and reference values
The capillary glucose test is done to control blood glucose at a certain time of day, and a glucometer should be used to test a small drop of blood drawn from the fingertip.
- The measurement of capillary glucose is best suited for people with hypoglycaemia.
- Prediabetes and diabetes.
- In which case it is recommended to do the dosage before and after meals so that glucose levels can be monitored and thus that they can adjust the diet.

Blood glucose can also be measured by a small sensor connected to the arm that constantly measures day and night. This sensor shows blood glucose levels in real time in the previous 8 hours and what is the trend of the glycemic curve for the next few moments. being this sensor very effective in terms of diabetes control and prevention of hiccups and hyperglycaemia.
After measuring glucose in the hair, it is important to compare the result with the baseline:
Less than 200 mg/dL
For newborns, it is difficult for the test to be fasted, so it is recommended that the newborn’s blood sugar be between 50 and 80 mg/dL.
If the person does not have diabetes, but the blood sugar value is in the column of modified blood glucose or diabetes, it is recommended to repeat the measurement the next day, and if the result persists, consult the endocrinologist to make the conclusive diagnosis. If the person has diabetes and the blood glucose levels remain above 200 mg / dL, they should consult the doctor to adjust the treatment or take insulin in the indicated doses.
In cases where blood glucose is less than 70 mg / dL, it is advisable to drink a glass of juice or a glass of sugary water, for example. Learn about the treatment of hypoglycemia.
Glucose levels can be controlled by simple changes in daily life, such as regular physical activity and a low balanced diet in high-sugar foods; However, if glucose levels do not return to normal, your doctor may recommend the use of certain medicines, which should be consumed as directed.
