Make A Note Of Your Readings

Blood Sugar Test – When, How & What

It may sound obvious, but you must record your readings. Note them down in a diary, a notebook or in your phone calendar. Some meters have software that lets you do this. You could try a diabetes app too.

You and your healthcare team can then look back over your results to see if you need to adjust your treatment.

How Do I Pick A Glucose Meter

Your doctor will make a recommendation. Check with your health insurance plan to see if it will pay for your BGM, its supplies, or a CGM. If so, your plan may only pay for a certain meter.

Shop around and compare costs. Consider what features are important to you. For example, some meters are made for people who have poor eyesight. If you want to pay a little more money, you can get a BGM that stores the results in its memory. This allows you to compare results from several days at one time.

Should I Test My Blood Glucose Levels

Attitudes to blood glucose testing can vary quite considerably. Some people with diabetes, particularly those that have not received any education on managing their diabetes, find that blood glucose testing is not helpful and only contributes to anxiety.

However, other people, particularly those that are aware of how to interpret results and take appropriate action, find blood glucose testing to be vital to their diabetes management

Some people with type 2 diabetes on non-insulin medication regimes may find it difficult to be prescribed blood glucose testing equipment.

What Is Diabetesand Types Of Blood Sugar Tests

The main source of blood sugar is the food that we eat. The glucose collected from our food is released into the bloodstream and used for energy. When there is a high blood sugar our body asks the pancreas to produce insulin which helps in using the blood sugar for energy production.

Diabetes disturbs the process. As a result of diabetes, disorder body will stop producing enough insulin or resist using insulin. The shortage of insulin or the bodys resistance in using causes too much blood sugar to remain in the bloodstream. This may lead to serious health problems such as kidney disorders, heart diseases, and even vision loss.

Besides Glucose What Other Tests Might Be Done

Normal Fasting Blood Sugar: Do You Have Diabetes?

Hemoglobin A1c is an indicator of long-term glucose control that is commonly ordered in patients with prediabetes and diabetes and can also be used as a screening test. Other less common tests, such as islet autoantibodies, insulin, and C-peptide, may sometimes be performed along with these tests to help determine the cause of abnormal glucose levels, to distinguish between type 1 and type 2 diabetes, and to evaluate insulin production.

Screening and Diagnosis

High levels of glucose most frequently indicate diabetes, but many other diseases and conditions can also cause elevated blood glucose.

A random glucose level in a person with signs and symptoms of diabetes and hyperglycemia that is equal to or greater than 200 mg/dL indicates diabetes.

The following table summarizes the meaning of fasting glucose results.

Is The A1c Test Used During Pregnancy

Health care professionals may use the A1C test early in pregnancy to see if a woman with risk factors had undiagnosed diabetes before becoming pregnant. Since the A1C test reflects your average blood glucose levels over the past 3 months, testing early in pregnancy may include values reflecting time before you were pregnant. The glucose challenge test or the oral glucose tolerance test are used to check for gestational diabetes, usually between 24 and 28 weeks of pregnancy. If you had gestational diabetes, you should be tested for diabetes no later than 12 weeks after your baby is born. If your blood glucose is still high, you may have type 2 diabetes. Even if your blood glucose is normal, you still have a greater chance of developing type 2 diabetes in the future and should get tested every 3 years.

Why Is High Blood Sugar So Bad

Think of the glucose in your body as sugar in a gas tank of a car. Over time, this glucose can clog and slow down other systems like the engine, making them work less efficiently.

One example is the kidneys. Your kidneys are made up of a web of delicate filters, and too much glucose can clog these filters, making them less effective. Over time, high blood sugar can lead to kidney disease or even kidney failure.

Other complications of long-term uncontrolled high blood sugar can include:

  • Damage to blood vessels

It’s possible to lose consciousness or even become comatose if your blood glucose levels become dangerously low. For people with diabetes, finding the right balance between high and low blood sugar is crucial.

Blood Glucose Levels Move Up And Down

What Is the Connection between Prednisone and Diabetes?

Your results can vary because of natural changes in your blood glucose level. For example, your blood glucose level moves up and down when you eat or exercise. Sickness and stress also can affect your blood glucose test results. A1C tests are less likely to be affected by short-term changes than FPG or OGTT tests.

The following chart shows how multiple blood glucose measurements over 4 days compare with an A1C measurement.

Blood Glucose Measurements Compared with A1C Measurements over 4 Days

The straight black line shows an A1C measurement of 7.0 percent. The blue line shows an example of how blood glucose test results might look from self-monitoring four times a day over a 4-day period.

Prevent Type 2 Diabetes

If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the CDC-led National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Having prediabetes puts you at greater risk for developing type 2 diabetes, but participating in the program can lower your risk by as much as 58% .

Types Of Blood Sugar Tests

You can take a blood sugar test two ways. People who are monitoring or managing their diabetes prick their finger using a glucometer for daily testing. The other method is drawing blood.

Blood samples are generally used to screen for diabetes. Your doctor will order a fasting blood sugar test. This test measures your blood sugar levels, or a glycosylated hemoglobin, also called a hemoglobin A1C test. The results of this test reflect your blood sugar levels over the previous 90 days. The results will show if you have prediabetes or diabetes and can monitor how your diabetes is controlled.

When and how often you should test your blood sugar depends on the type of diabetes you have and your treatment.

Who Is Most At Risk For Developing Diabetes

The following categories of people are considered “high-risk” candidates for developing diabetes:

  • Individuals who have overweight or obesity.

Diabetes Testing In Children

Many children have no symptoms before they are diagnosed with type 2 diabetes. Most of the time, diabetes is discovered when a blood or urine test taken for other health problems shows diabetes.

Talk to your doctor about your child’s risk for diabetes. If your child’s blood sugar tests are higher than normal, but not yet at the level of diabetes , your doctor may instruct you in specific diet and exercise changes to help your child avoid getting diabetes altogether. Children with type 2 diabetes or prediabetes are almost always overweight or obese.

Testing For Type 1 And Type 2 Diabetes

If diabetes is confirmed by the results of a blood test the type of diabetes you have is usually determined by factors like weight , age at diagnosis, family history and how quickly any symptoms came on.

The test results can also indicate if you are at risk of developing type 2 diabetes even if you dont have it now.

If youre being tested for type 1 diabetes then further blood tests can check your blood ketone levels. Following this you may be sent to hospital for further assessment.

Fasting Blood Glucose Level

A glucose level below 11.1 mmol/L on a random blood sample does not rule out diabetes. A blood test taken in the morning before you eat anything is a more accurate test. Do not eat or drink anything except water for 8-10 hours before a fasting blood glucose test. A level of 7.0 mmol/L or more indicates that you have diabetes.

If you have no symptoms of diabetes but the blood test shows a glucose level of 7.0 mmol/L or more, the blood test must be repeated to confirm you have diabetes. If you do have symptoms and the blood test shows a glucose level of 7.0 mmol/L or more, the test does not need to be repeated. See the separate leaflets called Type 1 Diabetes and Type 2 Diabetes for more details.

What Does It Mean To Have High Blood Sugar

Diagnosis of Diabetes Mellitus

Glucose levels in your bloodstream are normally regulated by your body and the insulin it makes. Insulin moves glucose into cells as they need it and stores the rest to use later.

When you have diabetes, either your body isn’t making any or enough insulin to move sugar into your cells, or there is more sugar in your blood than your body can process. This leads to a state called hyperglycemia, or high blood sugar.

When glucose is trapped in your blood and can’t enter your cells, several things can happen. If the problem is a lack of insulin or decreased sensitivity to insulin, the glucose stays in your blood and is unable to enter the cell and, therefore, starving your cells.

Symptoms of high blood sugar can include:

  • Excessive thirst or hunger
  • Increased urination

If you address your blood sugar level right away, these symptoms should subside. But blood sugar levels that remain high for most of the time, or become excessively high sometimes, can cause more serious complications.

A1c Blood Sugar Tests

The A1C test measures the percentage of glucose bound hemoglobin in a persons blood.

According to The National Institutes of Health , this gives a general picture of a persons blood glucose levels over the past 23 months .

Abnormal A1C test results do not necessarily mean a person has diabetes. A doctor will confirm these findings with another blood glucose test.

The doctor may recommend running more tests, such as blood work, to rule out other conditions that can affect blood sugar levels.

Why Would I Need This Test

You might need this test if you are at risk of developing diabetes, or if you have had any symptoms or test results suggesting diabetes.

The standard blood glucose tests measure your blood sugar level at a particular time. The OGTT measures how you respond to glucose.

Pregnant women can develop a particular type of diabetes called gestational diabetes, and will be asked to have an OGTT around 24 to 28 weeks of pregnancy. Gestational diabetes usually goes away after the baby is born.

The results of the fasting blood sugar test will come back as a number:

  • 99 mg/dL or lower: This is a normal fasting blood sugar level.
  • 100125 mg/dL: Fasting blood sugar in this range typically indicates prediabetes. This means your blood sugar levels are higher than normal but not high enough to be classified as diabetes.
  • 126 mg/dL or above: This indicates high blood sugar, the main sign of diabetes.

If you have a high fasting blood sugar level, your healthcare provider may repeat the test to make sure. If the test reveals that you have prediabetes, your healthcare provider will recommend you repeat the fasting blood sugar test every year or two. The results will help you know whether you are progressing to Type 2 diabetes.

What Is Blood Glucose Testing

Checking Blood Sugar (Glucose) Level | How to Use a Glucometer (Glucose Meter)

The term blood glucose generally refers to the amount of glucose in your blood. Blood glucose testing is done when a healthcare provider needs to see if a person has diabetes, or how well they are managing their diabetes. People who are diagnosed with diabetes need to check their blood glucose often to make sure their diabetes is in control.

To diagnose and monitor diabetes, healthcare providers test plasma glucose levels or the percentage of glycosylated hemoglobin in your bloodstream with a laboratory test. People who have diabetes test their plasma glucose with a portable meter at home.

Both the fasting plasma glucose and HbA1c tests are used to diagnose diabetes in nonpregnant adults. For an accurate diagnosis, all results must be confirmed by a second test on a different day.
