HbAc significance in prediabetes -

A normal A1C level is below 5. Within the 5. Get your A1C tested in addition to—not instead of—regular blood sugar self-testing if you have diabetes. Let your doctor know if any of these factors apply to you, and ask if you need additional tests to find out. However, your personal goal will depend on many things such as your age and any other medical conditions.

Work with your doctor to set your own individual A1C goal. People who are older, have severe lows, or have other serious health problems may have a higher goal. Two people can have the same A1C, one with steady blood sugar levels and the other with high and low swings.

Keep track and share the results with your doctor so you can make changes to your treatment plan if needed. Skip directly to site content Skip directly to search. Español Other Languages. All About Your A1C. Español Spanish. Minus Related Pages.

What Does the A1C Test Measure? In addition to macrovascular disease, are there other risks associated with low HbA1c levels? A study of insurance applicants which evaluated mortality results associated with various levels of HbA1C obtained between and found that relative mortality was increased for HbA1C levels below 5.

Conversely, hematologic problems may also result in falsely elevated HbA1C levels. For example, when red blood cell production is depressed in some anemic states e. Values may also be falsely high in the presence of abnormal hemoglobin e.

Fetal hemoglobin HbF or isckle hemoglobin HbS. Whereas chronic kidney disease may result in either falsely depressed or falsely elevated values. Underwriting and the future. Looking further ahead as an industry, evidence would suggest a closer study of the risks associated with elevated HbA1C levels in nondiabetics and how HbA1C might be used to help determine the risk of developing atherosclerosis.

As with any prudent underwriting assessment, it is important to consider all risk factors presented before determining a final decision. References 1.

Healthy habits has your blood sugar been up Sports nutrition tips for travel and competition lately? The Structured meal timetable test—also known HbAc significance in prediabetes the predlabetes A1C predibaetes HbA1c test—is a simple blood test that measures your average blood sugar levels over Structured meal timetable past predabetes months. Higher A1C levels are linked to diabetes complications, so reaching and maintaining your individual A1C goal is really important if you have diabetes. When sugar enters your bloodstream, it attaches to hemoglobin, a protein in your red blood cells. Everybody has some sugar attached to their hemoglobin, but people with higher blood sugar levels have more. The A1C test measures the percentage of your red blood cells that have sugar-coated hemoglobin.

In a Canadian context, A1C may identify more people as signifciance diabetes than FPG However, prediabetex studies suggest A1C may not identify as HbAc significance in prediabetes people as having diabetes compared to FPG or 2hPG In order to use A1C as a diagnostic criterion, A1C must be measured using a validated assay standardized to the National Glycohemoglobin Standardization Program—Diabetes Control and Complications Trial reference.

It is important to note that A1C may be misleading in individuals with various hemoglobinopathies, hemolytic or iron deficiency anemias, iron deficiency without anemia, Graves' disease and severe hepatic and renal disease 29—32although some evidence suggests that A1C may not be affected by these conditions in people without diabetes 33 see Monitoring Glycemic Control chapter, p.

Studies also show the relationship between glucose levels and A1C varies between people living at extremes of altitude In addition, studies of various ethnicities indicate that African Americans, American Indians, Hispanics and Asians have A1C values that are up to 0.

Research is required to determine if A1C levels differ in Canadians of African descent or Indigenous peoples. The frequency of retinopathy begins to increase at lower A1C levels in African-Americans than in Caucasians, which suggests a lower threshold for diagnosing diabetes in persons of African descent may be needed 39whereas a threshold of 6.

A1C values also are affected by age, rising by up to 0. More studies may help to determine if age- or ethnic-specific adjusted A1C thresholds are required for diabetes diagnosis.

In addition, A1C is not recommended for diagnostic purposes in children and adolescents as the sole diagnostic testpregnant women as part of routine screening for gestational diabetes, those with cystic fibrosis 42 or those with suspected type 1 diabetes see Diabetes and Pregnancy chapter, p.

S; Type 2 Diabetes in Children and Adolescents chapter, p. Other measures of glycemia, such as fructosamine, glycated albumin and 1,5-anhydroglucitol have not been validated for the diagnosis of diabetes. The decision of which test to use for diabetes diagnosis is left to clinical judgement Table 3.

Each diagnostic test has advantages and disadvantages 43 Table 4. It is preferable that the same test be repeated in a timely fashion for confirmation, but a random PG in the diabetes range in an asymptomatic individual should be confirmed with an alternate test.

In the case of symptomatic hyperglycemia, the diagnosis has been made and a confirmatory test is not required before treatment is initiated. In individuals in whom type 1 diabetes is likely younger or lean or symptomatic hyperglycemia, especially with ketonuria or ketonemiaconfirmatory testing should not delay initiation of treatment to avoid rapid deterioration.

If results of 2 different tests are available and both are above the diagnostic cut points, the diagnosis of diabetes is confirmed. Not all individuals with prediabetes will necessarily progress along the continuum of dysglycemia to develop diabetes.

Indeed, a significant proportion of people who are diagnosed with IFG or IGT will revert to normoglycemia. While people with prediabetes do not have increased risk for microvascular disease as seen in diabetes, they are at risk for the development of diabetes and CVD 45— Due to variability in the literature, it seems that IGT may or may not be more strongly associated with CVD outcomes than IFG, and A1C may or may not be more strongly associated with CVD outcomes than either IFG or IGT.

Individuals identified as having both IFG and IGT are at higher risk for diabetes as well as CVD than people with either IFG or IGT alone. People with prediabetes, particularly in the context of the metabolic syndrome, would benefit from CV risk factor modification.

While there is no worldwide consensus on the definition of IFG 48,49Diabetes Canada defines IFG as an FPG value of 6.

While there is a continuum of risk for diabetes in individuals with A1C levels between 5. While the American Diabetes Association defines prediabetes as an A1C between 5. The combination of an FPG of 6. Prediabetes and type 2 diabetes are often manifestations of a much broader underlying disorder 52including the metabolic syndrome, a highly prevalent, multifaceted condition characterized by a constellation of abnormalities that include abdominal obesity, hypertension, dyslipidemia and elevated BG.

Individuals with the metabolic syndrome are at significant risk of developing CVD. While metabolic syndrome and type 2 diabetes often coexist, those with metabolic syndrome without diabetes are at significant risk of developing diabetes.

Evidence exists to support an aggressive approach to identifying and treating people, not only those with hyperglycemia, but also those with the associated CV risk factors that make up the metabolic syndrome, such as hypertension, dyslipidemia and abdominal obesity, in the hope of significantly reducing CV morbidity and mortality.

Various diagnostic criteria for the metabolic syndrome have been proposed. Ina harmonized definition of the metabolic syndrome was established, with at least 3 or more criteria required for diagnosis 53 Table 6.

Key Messages The chronic hyperglycemia of diabetes is associated with significant long-term microvascular and cardiovascular complications. This permits the diagnosis of diabetes to be made on the basis of each of these parameters.

Key Messages for People with Diabetes There are 2 main types of diabetes. Type 1 diabetes occurs when the pancreas is unable to produce insulin. Type 2 diabetes occurs when the pancreas does not produce enough insulin or when the body does not effectively use the insulin that is produced.

Gestational diabetes is a type of diabetes that is first recognized or begins during pregnancy. Monogenic diabetes is a rare disorder caused by genetic defects of beta cell function. Prediabetes refers to blood glucose levels that are higher than normal, but not yet high enough to be diagnosed as type 2 diabetes.

Although not everyone with prediabetes will develop type 2 diabetes, many people will. You should discuss the type of diabetes you have with your diabetes health-care team.

There are several types of blood tests that can be done to determine if a person has diabetes and, in most cases, a confirmatory blood test is required to be sure. Definition of Diabetes and Prediabetes Diabetes mellitus is a heterogeneous metabolic disorder characterized by the presence of hyperglycemia due to impairment of insulin secretion, defective insulin action or both.

Classification of Diabetes The majority of cases of diabetes can be broadly classified into 2 categories: type 1 diabetes and type 2 diabetes, although some cases are difficult to classify.

This form includes cases due to an autoimmune process and those for which the etiology of beta cell destruction is unknown. Type 2 diabetes may range from predominant insulin resistance with relative insulin deficiency to a predominant secretory defect with insulin resistance. Ketosis is not as common.

Gestational diabetes mellitus refers to glucose intolerance with onset or first recognition during pregnancy. Other specific types include a wide variety of relatively uncommon conditions, primarily specific genetically defined forms of diabetes or diabetes associated with other diseases or drug use see Appendix 2.

Etiologic Classification of Diabetes Mellitus. Diagnostic Criteria Diabetes The diagnostic criteria for diabetes are summarized in Table 3 1.

If results of 2 different tests are available and both are above the diagnostic thresholds, the diagnosis of diabetes is confirmed. To avoid rapid metabolic deterioration in individuals in whom type 1 diabetes is likely younger or lean or symptomatic hyperglycemia, especially with ketonuria or ketonemia , the initiation of treatment should not be delayed in order to complete confirmatory testing. Metabolic Syndrome Prediabetes and type 2 diabetes are often manifestations of a much broader underlying disorder 52 , including the metabolic syndrome, a highly prevalent, multifaceted condition characterized by a constellation of abnormalities that include abdominal obesity, hypertension, dyslipidemia and elevated BG. In the presence of symptoms of hyperglycemia, a single test result in the diabetes range is sufficient to make the diagnosis of diabetes. If results of 2 different tests are available and both are above the diagnostic cut points the diagnosis of diabetes is confirmed [Grade D, Consensus]. To avoid rapid metabolic deterioration in individuals in whom type 1 diabetes is likely younger or lean or symptomatic hyperglycemia, especially with ketonuria or ketonemia , the initiation of treatment should not be delayed in order to complete confirmatory testing [Grade D, Consensus].

Changing from glucose to HbA1c for diabetes diagnosis: Predictive values of one test and importance of analytical bias and imprecision. Clin Chem Lab Med ; The FDA has approved or cleared a number of over-the-counter hemoglobin A1c test kits that you can use at home. At-home versions of the hemoglobin A1c test may not be as accurate as tests that are performed in a lab. But they offer a convenient alternative to testing in a medical office, which may be useful for some patients. Your doctor can advise you whether taking the test at home would be right for you and may be able to recommend a specific brand. The full cost of a hemoglobin A1c test depends on many variables, such as what type of hemoglobin A1c test your doctor orders for you, where the test is performed, whether you have medical insurance, and how much of the cost your insurance provider will cover. Hemoglobin A1c testing can involve several different charges. If your doctor has ordered a hemoglobin A1c test for you, many of these charges will be paid in part or in full by your insurance company. But you may still be responsible for out-of-pocket expenses such as deductibles or copayments. Your doctor or insurance provider can give you more information about the costs that you can expect to pay. The price of an at-home hemoglobin A1c test device can vary greatly depending on the test kit and manufacturer, the number of tests that come with the kit, and whether the device is covered by your insurance. You may also need to pay for replacement cartridges or other components if you use the device regularly. The hemoglobin A1c test requires a sample of blood. If the test is performed at a lab, the sample is taken through a needle from a vein. You do not need to make any specific preparations before getting your hemoglobin A1c test. But be sure to talk to your doctor about any additional tests that may be conducted during the same visit, since some of those tests may require you to fast or change your diet beforehand or to prepare in other ways. For a hemoglobin A1c test that uses a blood sample from a vein, the phlebotomist may start by tying a band at the top of your arm under your shoulder to put pressure on your vein, increasing blood flow. They will clean the skin around your vein using a sterile wipe, then insert a small needle into the vein in the pit of your elbow. Your blood sample will be collected in a tube attached to the needle. You may notice mild discomfort or stinging when the phlebotomist inserts or removes the needle. Most of the time, your blood draw will take five minutes or less to complete. If your hemoglobin A1c test uses a fingerstick blood sample, your doctor, nurse, or medical assistant will use a lancet to prick the tip of your finger until a drop of blood appears. You may feel a small amount of pain when your finger is pricked. The blood sample will be mixed with a special substance and then put into a cartridge that is inserted into the testing machine. For at-home testing, you will collect a blood sample from your finger and process the sample yourself. You can generally return to normal activities after the hemoglobin A1c test. If you receive a blood draw, the phlebotomist will put a small bandage over the injection site to make sure any bleeding stops. You may want to leave the bandage on for an hour or more. You may notice some bruising where the needle was inserted. Fingersticks do not typically cause lasting pain or discomfort. If needed, you can apply a bandage to your fingertip to stop the bleeding. If your hemoglobin A1c test was performed in a lab, you will generally receive test results in a few business days. Your results may be available to access online, or they may be sent to you through postal mail or email. Your doctor may call you or reach you by email to talk over your results. If you have a fingerstick hemoglobin A1c test, your test results will be available in a few minutes. Your doctor may discuss the results right away or may schedule an appointment to go over the results at a later date. Hemoglobin A1c test results are given as percentages. Your test report will also have information on the reference ranges used to interpret your results. Reference ranges are the test result ranges considered normal and the test result ranges that may indicate prediabetes or diabetes. Doctors use the reference ranges along with your overall health context to interpret the results of your hemoglobin A1c test. Your results will be interpreted differently depending on whether the test is used to diagnose or monitor diabetes that has already been diagnosed. For diagnostic hemoglobin A1c testing, many expert organizations cite these reference ranges:. While the hemoglobin A1c test can be used to diagnose diabetes, doctors do not often rely on the results of just one test to make this diagnosis.
