How many times a day should I measure my blood sugar?

It depends on your individual condition. Measurements are often taken while fasting, two hours after a meal, and before bedtime. Consult your clinician to determine the appropriate schedule.

Can I test a site other than my fingers?

Some devices can also be used on the forearm or palm, but fingertip testing is generally the most accurate.

Do I need to wash my hands before measuring?

Yes, food or foreign substances may cause inaccurate readings. Wash your hands with soap and dry them completely before measuring.

How to Use a Blood Glucose Meter

Step-by-step guide to accurate measurements

Before reading this article

When you first get a blood glucose meter, it may seem complicated. However, it is easy to use once you learn the correct steps.

Summary of key concepts

A blood glucose meter uses a small blood sample from your fingertip to check your blood sugar level right away. It is an important self-management tool for people with diabetes.

Components of a blood glucose meter

**Meter**: The device and screen that display the reading
**Lancet**: A small needle used to prick the side of a fingertip
**Lancing device**: The device that holds and releases the lancet
**Test strips**: Disposable strips that collect the blood sample for the meter

Tips that actually help

Step 1: Get ready

Wash your hands thoroughly with soap and dry them completely.
Prepare the meter, lancing device, lancet, and test strip.
When you insert the test strip into the meter, it automatically turns on.

Step 2: Draw blood

Insert the lancet into the lancing device and adjust the depth. (Start at a medium setting.)
Place the lancing device against the side of your fingertip and press the button.
Gently squeeze from the base of the finger toward the tip until a sufficient drop of blood forms.

Step 3: Measure

When you place the tip of the test strip on a drop of blood, it is automatically absorbed.
After 5 to 10 seconds, the reading will be displayed on the meter.
Record the values and safely dispose of used lancets and test strips.

Common mistakes beginners make

**Testing without washing your hands**: Food residue can cause a falsely high reading.
**Insufficient blood volume**: An error occurs if the test strip does not absorb enough blood.
**Not checking the test strip expiration date**: Expired test strips may be less accurate.
**Using the same finger repeatedly**: Alternate fingers to reduce pain and calluses.

Key Summary

Wash and dry your hands thoroughly before measuring.
Minimize pain by adjusting the depth of the lancing device
Secure sufficient blood volume
Record numbers and identify patterns
