Answer From M. Regina Castro, M.D. When used correctly, blood glucose monitors — small devices that measure and display your blood sugar level — are usually accurate. But occasionally they may be incorrect.
Is testing blood sugar at home accurate?
While a lot of research and technology has gone into the making of home diabetes test devices, there are still high chances of them not giving results as precise as those by professional centers that conduct blood test for diabetes. Many factors can affect the results of a sugar test conducted by you at home.
Can you get a false high blood sugar reading?
This interaction has resulted in false readings of hyperglycemia and unnecessary insulin administration, sometimes leading to injury and death. Additionally, falsely elevated glucose readings could mask true hypoglycemia, which also could result in fatal consequences if left untreated.
What is the most accurate blood sugar test?
Best Budget: Accu-Chek Aviva Plus Blood Glucose Monitoring System. This glucometer model from AccuChek is well-known as one of the most accurate blood sugar-monitoring devices on the market.
Can a glucose test be wrong?
When used correctly, blood glucose monitors — small devices that measure and display your blood sugar level — are usually accurate. But occasionally they may be incorrect.
What is normal blood sugar by age?

…
Normal blood sugar levels for adolescents.
| Normal blood sugar levels for adolescents | |
|---|---|
| Age 6-12 | mg/dL |
| Fasting | 80-180 |
| Before meal | 90-180 |
| 1-2 hours after eating | Up to 140 |
Does drinking water affect blood sugar?
Drinking water before a fasting blood sugar test can actually decrease blood sugar levels, or at least prevent levels from getting too high. Water allows more glucose to be flushed out of the blood. When you’re dehydrated, it means your overall blood volume is lower than normal, but your sugars will be the same.
What causes false high blood sugar?
However, various factors such as application errors, extreme environmental conditions, extreme hematocrit values, or medication interferences may potentially falsify blood glucose readings. Incorrect blood glucose readings may lead to treatment errors, for example, incorrect insulin dosing.
What causes false low blood sugar readings?
Accuracy may be limited due to strip manufacturing variances, strip storage, and aging. They may also be due to limitations on the environment such as temperature or altitude or to patient factors such as improper coding, incorrect hand washing, altered hematocrit, or naturally occurring interfering substances.
Is Accu-Chek accurate?

What is the normal blood sugar level?
Fasting Blood Sugar Test
A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes.
How do you feel when blood sugar is high?
If your blood sugar level is too high, you may experience: Increased thirst. Frequent urination. Fatigue.
Is 5.7 blood sugar normal?
In general: A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L ) is considered prediabetes. This result is sometimes called impaired fasting glucose.
Does blood sugar rise with age?
This sugar is either used immediately for energy or stored for later use by exercising muscles. But as we age, the pancreas produces less insulin — which means blood sugar remains elevated for longer.
Does coffee raise blood sugar?
For most young, healthy adults, caffeine doesn’t appear to noticeably affect blood sugar (glucose) levels, and having up to 400 milligrams a day appears to be safe.
What food washes out sugar from blood?

Does urinating lower blood sugar?

Why is my blood sugar high in the morning but normal all day?
High blood sugar in the morning may be caused by the Somogyi effect, a condition also called “rebound hyperglycemia.” It also may be caused by dawn phenomenon, which is the end result of a combination of natural body changes.
Why do I feel worse when my blood sugar is normal?

Is Accu Chek a good meter?
Roche Diabetes Care states that the Accu-Chek Guide meter and strips are more accurate than any of their previous Accu-Chek products. According to the FDA, clinical results submitted to regulators show that with the lowest glucose readings below 75 mg/dL, Accu-Chek Guide hits an accuracy of 100 percent.
Is fasting blood sugar of 135 high?
Less than 100 mg/dL = normal. Between 110–125 mg/dL = impaired fasting glucose (i.e., prediabetes) Greater than 126 mg/dL on two or more samples = diabetes.
Is fasting sugar 110 normal?
A fasting blood sugar between 110 and 125 would be considered in the “prediabetes” range. Less than 110 is normal and greater than 126 is diabetes. These abnormal blood sugar levels usually happen when a person’s tissues don’t respond well to a hormone [insulin] signal to take up sugar from the blood.
Is fasting blood sugar 119 high?
Low blood sugar or hypoglycemia is when blood levels drop below 70 mg/dL in diabetics or around 55 mg/dL (3 mmol/L) in healthy people. High blood sugar or hyperglycemia is when your blood glucose levels are too high, above 126 mg/dL or 7 mmol/L. The normal fasting blood sugar range in healthy people is 70 – 125 mg/dL.
