For individuals with "three highs" (high blood sugar, high blood pressure, high blood lipids), a blood glucose meter is an essential tool for daily health monitoring. It helps users understand their blood sugar fluctuations, detect abnormalities promptly, and seek medical assistance when needed. Given the variety of models and types available on the market, this article will guide you on how to choose the right blood glucose meter for accurate measurement and management of blood sugar.

Importance of Blood Glucose Meters

A blood glucose meter measures the concentration of glucose in the blood using blood samples, typically drawn from a fingertip with a small needle. Home testing helps users monitor their blood sugar levels and adjust their dietary habits accordingly.

Diabetes patients, pregnant women, those with high or low blood sugar, and patients with high ketone levels can benefit from home blood glucose monitoring. For diabetes patients, glucose meters are especially crucial in monitoring and maintaining blood sugar levels, preventing excessively high or low readings, and reducing the risk of diabetes-related complications.

Reference Values for Blood Glucose

Blood glucose is measured in "millimoles per liter" (mmol/L) and "milligrams per deciliter" (mg/dL). Some blood glucose meters offer unit conversion features, so users should pay attention to the units displayed to avoid misinterpreting blood sugar levels.

	Healthy Individuals	Diabetes Patients
Fasting Blood Sugar	4.0-5.4 mmol/L	≥ 7.0 mmol/L
Postprandial (2 hours)	< 7.8 mmol/L	≥ 11.1 mmol/L

Key Considerations When Buying a Blood Glucose Meter

1. Certification

Ensure the blood glucose meter has a valid medical device license, which guarantees safety during use and accuracy of test results. Look for certifications from local health authorities, as well as international standards like the US FDA, EU CE, and ISO9001.

2. Testing Principle

Blood glucose meters typically use either "photochemical" or "electrochemical" methods for testing.

Photochemical	Electrochemical
Lower cost Prone to contamination, affecting the accuracy of the result larger error margin (±0.8) requires regular cleaning and calibration suitable for budget users	Smaller error margin (±0.2) less prone to contamination and usually does not require calibration ideal for long-term users or those needing high accuracy

3. Blood Sampling Method

There are mainly two blood sampling methods available: capillary and siphon.

Capillary Sampling	Siphon Sampling
Requires more blood accuracy may be affected by insufficient volume or incorrect positioning suitable for experienced users	Requires less blood simpler sampling method reduces potential errors ideal for beginners and those averse to pain

There are also needle-free blood glucose meters that attach a sensor to the skin. These sensors use a small cannula to measure blood sugar. Although still not widespread, they may become mainstream in the future, ideal for those who dislike needles or fear pain.

4. Features

Different functions can help users better understand their health status:

• Memory Function: Continuously records blood sugar levels, dates, and times for tracking changes—especially useful for individuals with memory issues.
• Automatic Temperature Calibration: Built-in temperature sensors automatically adjust for environmental conditions, ensuring results are unaffected by temperature fluctuations—suitable for users in variable climates.
• Average Blood Sugar and Reminder Functions: Automatically calculates averages over time and sets reminders for regular testing, ideal for long-term monitoring.

5. Ease of Use

Simple operation is crucial for elderly users. Choose a meter with fewer steps and a larger display for easier reading. Some meters feature fully automatic modes with automatic power on, testing, and shut-off functions, reducing complexity and enhancing convenience and accuracy.

6. Power Source

Most blood glucose meters use button cells or proprietary batteries, which can be difficult to replace. Meters that use standard AA batteries are more convenient, especially for users requiring frequent testing.

7. Packaging of Test Strips

Blood glucose test strips are sensitive to humidity and should be stored in dry environments; otherwise, moisture can affect their accuracy. Bottled strips should generally be used within three months of opening to avoid prolonged exposure to air. Individual users may consider single-pack strips for better protection.

Blood Glucose Meter Operation Process

1. Wash your hands thoroughly before taking a blood sample.
2. Insert the dedicated test strip into the meter, ensuring it is fully inserted.
3. Load a clean lancet into the lancing device and adjust the depth setting (higher number means deeper puncture).
4. Disinfect the puncture site with an alcohol swab, and wait for it to dry before drawing blood.
5. It is recommended to puncture the side of the fingertip to reduce pain.
6. Press the lancing device against the puncture site, squeeze out an adequate amount of blood, and apply it to the test strip.
7. While waiting for the reading, apply pressure with a cotton ball to stop any bleeding at the puncture site.
8. Record the blood sugar reading for future reference.
9. Dispose of used lancets in a puncture-proof container.

Blood Glucose Meter Usage Precautions

Before Using the Meter:

• Regularly check the power source and replace batteries as needed.
• Use compatible test strips and check their expiration dates.
• Follow healthcare instructions for testing at specific times (e.g., fasting, pre-meal, post-meal 2-3 hours, before bed).

When Turning on the Meter:

• Check the display to ensure all segments are functioning properly.
• Confirm that the displayed measurement unit is the one you normally use.

When Measuring Blood Sugar:

• Wash hands to prevent contamination of the blood sample.
• Ensure the test strip is fully inserted into the meter.
• Use a disinfected lancet for blood sample extraction.
• Apply the appropriate amount of blood to the test strip (too much or too little can affect accuracy).

When Changing Test Strips:

• Verify that the code on the meter matches the code on the test strip vial.
• Follow instructions for quality control checks to calibrate the meter.

Maintenance of Blood Glucose Meters and Test Strips

• Never insert expired or used strips into the meter, as this can damage it.
• Avoid storing the meter, strips, and control solutions in extreme temperatures or humidity.
• Keep test strips in their original container, ensuring it is tightly sealed.
• Do not refrigerate test strips to prevent moisture that could affect accuracy.
• Store strips in a cool, dry place, away from direct sunlight.
