Blood Sugar Checker
Check your blood glucose reading and understand how the value may be interpreted depending on when it was measured.
Understanding Blood Sugar
Blood glucose levels change throughout the day. Meals, exercise, medication, stress, illness, and other factors can affect your reading.
For this reason, the time at which your blood sugar was measured is important when interpreting the result.

About Blood Sugar Readings
Fasting
A fasting reading is generally taken after not eating for at least 8 hours.
Before a Meal
A pre-meal reading can be useful for monitoring glucose, particularly for people managing diabetes.
2 Hours After a Meal
Post-meal glucose provides information about how the body is responding to food.
Random
A random reading can be taken at any time, but its meaning depends on factors such as when you last ate.
