What Is The Fasting Blood Sugar Test Used For

What is A Normal Blood Glucose?

The fasting blood sugar test is also used to test the effectiveness of different medication or dietary changes on people already diagnosed as diabetic

Fasting blood sugar levels are measured by taking a blood test after a period of fasting, usually of 8 hours without food. Typically, fasting blood glucose levels are taken in the morning before any breakfast is eaten. When having your fasting blood glucose levels take, you should not have any drinks apart from water during the period of fasting.

A fasting blood glucose test can be useful to see how well the body is able to manage blood sugar levels in the absence of food. When we do not eat for several hours, the body will release glucose into the blood via the liver and, following this, the bodys insulin should help to stabilise blood glucose levels.

A fasting blood glucose test therefore shows:

  • Whether the body is able to bring down the raise in blood glucose levels from the previous meal
  • How effectively the body copes with its own release of glucose

The target for fasting blood glucose levels are the same as the targets for before meal readings.

  • For adults with diabetes, the target level is between 4 and 7 mmol/l
  • For children with diabetes, the target level is between 4 and 8 mmol/l

However, ;some people may be set individual targets, by their doctor, that differ to the above levels.

Who Is Most At Risk For Developing Diabetes

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

  • Individuals who are overweight or obese
  • Individuals who are 45 years of age or older
  • Individuals with first-degree relatives with diabetes
  • Individuals who are African-American, Alaska Native, American Indian, Asia American, Hispanic/Latino, Native Hawaiian, Pacific Islanders,
  • Women who developed diabetes while they were pregnant or gave birth to large babies
  • Individuals with high blood pressure
  • Individuals with high-density lipoprotein below 25 mg/dl or triglyceride levels at or above 250 mg/dl
  • Individuals who have impaired fasting glucose or impaired glucose tolerance
  • Individuals who are physically inactive; engaging in exercise less than three times a week
  • Individuals who have polycystic ovary syndrome, also called PCOS
  • Individuals who have acanthosis nigricans — dark, thick and velvety skin around your neck or armpits

In addition to testing the above individuals at high risk, the American Diabetes Association also recommends screening all individuals age 45 and older.

Diagnosing Prediabetes Type 2 And Type 1 Diabetes

Depending on which country or medical organization you ask, the qualifying numbers for normal versus prediabetes versus diagnosed type 1 or type 2 diabetes can vary slightly. The following blood sugar and A1c the general results are used to diagnosed prediabetes and diabetes according to sources including the American Diabetes Association and Diabetes UK:;;

Prediabetes

  • HbA1c: 5.7 to 6.4 percent
  • Fasting: 100 to 125 mg/dL
  • 2 hours after a meal: 140 mg/dL to 199 mg/dL

Type 1 or 2 diabetes

  • HbA1c: 6.5 percent or higher
  • Fasting: 126 mg/dL or higher
  • 2 hours after a meal: 200 mg/dL or higher

Please note: Type 1 diabetes tends to develop very quickly which means that by the time symptoms are felt, blood sugar levels are generally well above 200 mg/dL all the time. For many, symptoms come on so quickly they are dismissed as the lingering flu or another seemingly ordinary virus.

By the time blood sugar levels are tested, many newly diagnosed type 1 patients will see levels above 400 mg/dL or higher. If you do suspect that you or a loved-one has type 1 diabetes, visit your primary care or urgent care immediately and ask for a urine test to measure ketones in addition to testing blood sugar levels and A1c.

Factors That Can Affect Blood Sugar Levels

If you have prediabetes or diabetes, you may have insulin resistance or an inability to produce insulin. This means your body has difficulty regulating blood sugar levels on its own.

Its a delicate balance to maintain, so the following list can help you familiarize yourself with factors that can cause your blood glucose levels to go up or down.

Chart For Normal Fasting Blood Sugar Levels

TAKE-HOME TIPS

Normal;fasting blood sugar levels;are considered fasting blood sugar levels;between 80 mg/dl and 100 mg/dl.;However, nowadays, this normal range is changed due to different reference ranges of laboratories use.;

These figures come out when you measure your blood sugar level in the morning after have been fasting for at least 8 hours.

Normal Hba1c For Person Without Diabetes

For someone who does not have diabetes, a normal HbA1C level is below 5.7%. An A1C between 5.7% to 6.4% is indicative of prediabetes.

Its recommended that adults over the age of 45 or adults under 45 who are overweight and have one or more risk factors for diabetes have a baseline A1C checked. If the result is normal, the A1C should be checked every 3 years. If the result indicates prediabetes, the A1C should be checked every 1 to 2 years.

Fasting Blood Glucose Level Test Preparation

What should you do if your doctor orders a fasting blood sugar test? The preparation is the same as when you take a fasting test for cholesterol. First, be sure to find out if you need to schedule an appointment for your test . Ask your doctor what time is best to take it.

Then:

  • Schedule your test if necessary
  • Ask your doctor if you need to change any of the medications you take on the morning of the test
  • If you normally drink coffee or have caffeine, ask your doctor if that is okay. It may not be, since it affects blood sugar levels
  • Fast for at least 8 hours before your test. Usually, an overnight fast is most convenient
  • You can drink water

Nonfasting Glucose And Ihd And Mi Observational Estimates

Risk of IHD and MI increased stepwise with increasing nonfasting glucose levels .2). Subjects with a level >11 mmol/l had their event on average 20 years before subjects with levels <5 mmol/l . Age- and sex-adjusted hazard ratio for IHD was 6.9 in subjects with nonfasting plasma glucose levels 11 mmol/l versus <5 mmol/l . Corresponding estimates were 6.2 when adjusting multifactorially; 4.7 multifactorially including BMI; 3.8 multifactorially including total and HDL cholesterol; 5.8 multifactorially including hypertension; and 2.3 multifactorially including all the above. Corresponding values for MI were 9.2 , 8.3 , 6.8 , 6.0 , 7.5 , and 4.8 .

A normal fasting blood glucose for someone who does not have diabetes ranges from 70 to 99 mg/dl. The American Diabetes Association recommends a routine screening for type 2 diabetes starting at age 45. If the results are normal, the screening should be repeated every 3 years.

If have diabetes risk factors, which include being overweight or obese, having a family history of type 2 diabetes, having a history of gestational diabetes, or being of a certain race/ethnicity , you should be screened for diabetes sooner than age 45.

Children and adolescents who have diabetes symptoms or who are overweight and have a family history of type 2 diabetes, are of African American, Latino, Asian American, Native American or Pacific Islander descent, who have signs of prediabetes or a mother who had gestational diabetes should be tested beginning at age 10 and then every 3 years thereafter.

A fasting blood sugar of 100 to 125 mg/dl is indicative of prediabetes, which is a condition where blood sugar levels are above normal but not high enough to be considered diabetes. Prediabetes is a risk factor for type 2 diabetes, heart disease and stroke. Its managed by lifestyle changes and, in some cases, medication.

Whats Considered A Normal Glucose Level

Your doctor will likely test your blood glucose levels as a screening test for diabetes during a standard yearly check-up. Additionally, many people track their glucose at home with an over-the-counter finger-prick test. When you check blood glucose , either at a doctors office or with a home finger stick glucose monitor, the results are in milligrams of glucose per deciliter of blood.

One of the most common glucose measurements is fasting plasma glucose or fasting blood glucose , and its found by checking blood glucose levels after not having any calories at least eight hours before the test. According to the American Diabetes Association , people can be classified into three categories depending on their fasting plasma glucose levels: normal, prediabetes, and diabetes. To be considered normal, fasting glucose must be under 100 mg/dl.

Of note, CGM devices measure interstitial glucose levels compared to blood/plasma glucose levels measured in the FPG tests. While interstitial glucose and blood/plasma glucose levels correlate highly, they are not precisely the same, and diagnoses are not made from interstitial measurements.

Below is a summary overview of data about 24-hour glucose trends in nondiabetic individuals wearing CGM to gain a better understanding of whats normal.

Symptoms Signs Causes Of Levels Of High Blood Sugar In The Blood

High blood sugar or hyperglycemia is an abnormally high blood sugar level in the blood. Hyperglycemia is a hallmark sign of diabetes and prediabetes.

Signs and symptoms of hyperglycemia include blurred vision, headaches, hunger, and …

    The normal ranges for blood sugar levels in adults who do not have diabetes before eating or fasting the range begins at 72-99mg/dL while fasting ranges for those being treated for type 1 or type 2 diabetes range from 80 -130 mg/dL. According to the American Diabetes Association normal blood sugar levels before and after eating should be 80-130 mg/dL before eating a meal , and less than 180 mg/dL about 1-2 hours after eating a meal

    High blood sugar ranges for people who dont have diabetes begins at 140 mg/dL or greater while for those being treated for diabetes, the high range begins at 180 mg/dL , called hypoglycemia.

      Difference Between Fasting And Nonfasting Blood Sugar

      Fasting vs Nonfasting Blood Sugar ;

      The main energy source consumed by humans in everyday life is carbohydrates, and they are then converted into simple sugars like glucose. The production of energy is thus, dependent on the level of glucose in the blood, and different types of hormones are also facilitating the blood levels of glucose. Hormones like insulin are present when there are adequate levels of blood glucose and help to store it as glycogen and fat, in the muscle tissues, and liver. However, at times of poor food intake, hormones like glucagon and cortisol help produce new glucose from non carbohydrate materials and through the breakdown of glycogen . Levels of blood sugar are thus variant upon different factors of food intake, the time from the last meal, and concurrent diseases and medications. Here, we will elaborate on two main glucose levels, which is the fasting glucose level and the non-fasting glucose level.

      Low Blood Sugar Chart And Action Plan

      What is a desirable non

      Low blood sugar is also called hypoglycemia. The numbers below represent values in the hypoglycemic range and require action to bring blood sugar levels up into a normal range.

      Alert Level and Treatment Plan
      50 mg/dL or underRed Flag: Blood sugar is critically low and requires immediate treatment.

      If a person is unable to speak and/or is not alert, treat with glucagon via injection or nasal spray. Call emergency medical response if necessary. Do not place food or drink into the mouth.

      If a person is alert and able to speak clearly, treat with 15 grams of rapid-acting carbohydrate such as glucose gel, 4 oz regular soda, or fruit juice. Re-test blood sugar in 15 minutes and repeat as needed to bring blood sugar within range.

      51-70 mg/dLRed Flag: Blood sugar is below normal levels and requires immediate treatment.

      Treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes. Repeat treatment as needed to bring blood sugar within range.

      71-90 mg/dLYellow Flag: Blood sugar levels should be watched and treated as needed.

      If youre having symptoms of low blood sugar, treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes.

      Repeat treatment or follow with a meal. If it is meal time, move forward with eating the meal. People often fall into this range when they are late for a meal or have been especially active.

      What Is Blood Glucose Anyway

      Blood glucose, or sugar, is sugar that is in your blood . It comes from the food that you eat foods that contain carbohydrate, such as bread, pasta and fruit are the main contributors to blood glucose. The cells in our bodies need glucose for energy and we all need energy to move, think, learn and breathe. The brain, which is the command center, uses about half of all the energy from glucose in the body.

      Hba1c Test For Diabetes Diagnosis

      An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.

      Indications of diabetes or prediabetes are given under the following conditions:

      • Normal: Below 42 mmol/mol
      • Prediabetes: 42 to 47 mmol/mol
      • Diabetes: 48 mmol/mol

      There are two types of blood sugar levels that may be measured. The first is the blood glucose level we get from doing finger prick blood glucose tests. These give us a reading of how high our levels are at that very point in time.

      The second is the HbA1c reading, which gives a good idea of our average control over a period of 2 to 3 months. The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children.

      Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol .

      Research has shown that high blood glucose levels over time can lead to organ and circulation damage.

      Keeping blood glucose above 4 mmol/l for people on insulin or certain medications for type 2 diabetes is important to prevent hypos occurring, which can be dangerous.

      Your doctor may give you different targets. Children, older people and those at particular risk of hypoglycemia may be given wider targets.

      Low Blood Sugar Levels

      Blood sugar that is too low can cause symptoms such as:

      • shaking and sweating
      • headache
      • tiredness

      As with low blood sugar, high blood sugar may cause loss of consciousness or seizures if people leave them untreated. Persistent high levels can increase the risk of serious complications that doctors relate to diabetes, such as cardiovascular disease.

      What Is Prediabetes

      What is normal blood sugar level for non-diabetics?

      Before people develop type 2 diabetes, they almost always have “prediabetes”blood sugar;levels that are higher than normal but not yet high enough to be diagnosed as diabetes.

      Doctors sometimes refer to prediabetes as impaired glucose tolerance or impaired fasting glucose , depending on what test was used when it was detected. This condition puts you at a higher risk for developing type 2 diabetes and cardiovascular disease.

      When Things Go Awry

      When we eat food, the pancreas goes to work, releasing enzymes that help to break down food and hormones that help the body handle the influx of glucose. One of these hormones is insulin, and it plays a key role in managing glucose levels in the blood.

      And here is where things can go wrong. If the pancreas doesnt make enough insulin or stops making it altogether, in the case of type 1 diabetes glucose levels in the blood can rise too high. Another scenario is that the pancreas makes enough insulin but the cells have trouble using it properly, causing blood glucose levels to rise. This is called insulin resistance and is the hallmark of type 2 diabetes.

      In the short term, high blood glucose levels can make you feel downright bad. Thirst, frequent trips to the bathroom, fatigue and weight loss are all symptoms of high blood glucose . If not treated, more serious issues can occur, such as diabetic ketoacidosis. Chronic high blood glucose levels can lead to complications such as heart, kidney and eye disease, as well as nerve damage. So, its all about the blood glucose.

      Blood Sugar Before And After Meals

      There are many different times of day when you can check your blood sugar, but the most important times are typically before and after a meal. Checking your blood sugar before a meal can help you decide which foods to eat and how much insulin to take. According to the ADA’s Standards of Medical Care in Diabetes 2019, a healthy blood sugar level before a meal should fall somewhere between 80 and 130 mg/dL.

      Checking your blood sugar after you eat tells you how your body is processing your meal and whether or not you currently have enough insulin in your system. But don’t check your blood sugar immediately after you finish your food. “If a patient wants to see their body’s response to a meal, they need to wait two hours before checking blood glucose,” says Samar Hafida, MD, an endocrinologist at Boston’s Joslin Diabetes Center. “That’s how long it takes for the body to fully digest carbs.”

      To see the effect of a meal on your blood glucose, measure your blood sugar two hours after starting your meal; that’s when your blood sugar will peak. According to the ADA, the goal is that this peak, non-fasting glucose level will be less than 180 mg/dL.
