Home Blood Glucose Test
A home blood glucose test measures the
amount of a type of sugar, called glucose, in your blood at the time of
testing. The test can be done at home or anywhere, using a small portable
machine called a blood glucose meter.
The American Diabetes
Association (ADA) recommends that you stay within the following blood sugar
level ranges. But, depending on your health, you and your doctor may set a
different range for you.
Recommended blood sugar level ranges
| For nonpregnant people with diabetes:
mg/dL (3.9 mmol/L) to 130 mg/dL (7.2 mmol/L) before
- Less than 180
mg/dL (10 mmol/L) 1–2 hours after the start of a meal
| For women who have diabetes related to pregnancy
- 95 mg/dL (5.3 mmol/L) or less, before breakfast
- 140 mg/dL (7.8 mmol/L) or less, 1 hour
after the start of a meal, or 120 mg/dL (6.7 mmol/L) or less 2 hours after the start of a meal
Many conditions can change blood
glucose levels. Your doctor will discuss any significant abnormal results with
you in relation to your symptoms and past health.
