How to use a glucometer

• Learn more about the use of the glucometer.
• Remember that proper preparation is essential to obtain reliable and accurate results.

Performing the measurement

To perform the measurement with your glucometer, follow these steps:

1. Wash your hands with soap and water and dry them well.
2. Insert a test strip into the glucometer. Make sure the code on the strip matches the one displayed on the glucometer screen.
3. Aim the device's needle at the tip of your finger (preferably on the side) and press the button to collect a drop of blood.
4. Apply the drop of blood to the reactive part of the strip. Make sure that there is enough blood to completely cover the reactive area.
5. Wait for a few seconds while the glucometer processes the data.
6. Read the results from your glucometer display. The value shown represents the concentration of glucose in your blood in milligrams per deciliter (mg/dl).

Remember to clean your device after each use and dispose of used test strips properly. Also, always keep another source of sugar, such as drinks or candy, handy in case you experience hypoglycemia during measurement.

Interpreting results

After performing a test with your glucometer, it will be necessary to interpret the results to understand whether blood sugar levels are normal or if measures need to be taken.

Normal blood glucose levels

Normal blood glucose levels vary depending on the time of day and the person's age. In general, the following values are considered normal:

• Before meals: between 70 and 130 mg/dL (3.9-7.2 mmol/L)
• After meals: less than 180 mg/dL (10 mmol/L) two hours after eating

Elevated blood glucose levels

If test results indicate a blood sugar level higher than normal values, there may be several reasons. For example:

• The person may have diabetes or a pre-diabetic condition
• There may have been incorrect administration of insulin or an insufficient dose
• There may have been excessive intake of carbohydrates or sugars

Low blood glucose levels

If test results indicate a blood sugar level lower than normal values, there may be several reasons. For example:

• The person may have eaten too little or skipped a meal
• There may have been an overdose of insulin or an excessive dose of medication

For diabetes:

• There may have been excessive physical activity compared to calorie intake

In any case, if the test results indicate values outside normal limits, it is important to consult a doctor for further checks and evaluations.

Practical tips

Here are some practical tips for using the glucometer:

Choose the right time for measurement

It is important to choose the right time to measure blood sugar levels. In general, it is advisable to do so before meals or two hours after consuming them. However, if monitoring blood sugar in relation to physical activity or other specific factors, it may be necessary to take measurements at different times.

Clean and disinfect the device

Prior to each use of the glucometer, make sure it is clean and disinfected. Use a soft, damp cloth to remove any blood residue or other impurities from the device. Additionally, a specific disinfectant can be used to keep the glucometer clean and hygienic.

Use new and sterile lancets

To ensure reliable results, it is important to use new and sterilized lancets for each blood sugar measurement. This helps prevent contamination risk and ensures greater accuracy in reading values.

Maintain a record of measurements

Keeping track of blood sugar measurements can help identify any trends or variations in sugar levels over time. A paper diary or specific app can be used to record values and analyze them over time.

Consult with your doctor

If you have any doubts about using the glucometer or managing your blood sugar, it is always advisable to consult with your trusted doctor. This helps avoid mistakes and ensures greater safety in managing your health.

• Remember to always follow the manufacturer's instructions for using the glucometer
• Keep the device in a cool, dry place away from sources of heat or moisture
• Use only compatible test strips with your glucometer

Conclusion

The use of a glucometer can be very useful for monitoring blood sugar levels and preventing potential complications related to diabetes. However, it is important to follow some practical rules to ensure reliable results and proper management of the device. With these simple tips, it will be possible to use the glucometer effectively and safely under the supervision of your doctor.
