Ac vs blood glucose -

A1C target levels can vary by each person's age and other factors, and your target may be different from someone else's.

A1C test results are reported as a percentage. The higher the percentage, the higher your blood glucose levels over the past two to three months. The A1C test can also be used for diagnosis, based on the following guidelines:. Another term you may come across when finding out your A1C is eAG.

Your doctor might report your A1C results as eAG. eAG is similar to what you see when monitoring your blood glucose at home on your meter.

However, because you are more likely to check your blood glucose in the morning and before meals, your meter readings will likely be lower than your eAG. Importantly, measurement of fructosamine, which is glycated albumin and protein, suffers from several limitations In addition, some authors have questioned the statistical analysis which is not standard used in determining the glycation gap and noted the statistical tautology that the outcome is correlated with the residual from a regression Importantly, the postulate of a glycation gap remains unsubstantiated by data because glycation rates cannot be measured accurately in vivo.

In addition, the hemoglobin glycation index difference between observed A1C and that predicted from blood glucose is not an independent predictor of the risk of microvascular complications 43 , and the possible clinical significance of the glycation gap is unclear. Accumulating evidence supports the hypothesis that race influences A1C.

Initial studies in patients with diabetes reported statistically significant differences in A1C concentrations among races While adjusted for factors that may influence glycemia, it remains possible that these differences may be due to variations in glycemic control.

More compelling support was provided in NHANES III where Mexican Americans and blacks had higher average A1C values than whites 45 , Similar findings were observed in adults with impaired glucose tolerance in the Diabetes Prevention Program 47 and validated in a cross-sectional analysis of two studies Collectively these data suggest that there are differences in A1C concentrations among racial groups.

However, it is not clear that these changes have clinical significance. A1C was measured in the Atherosclerosis Risk in Communities ARIC study in 11, adults who did not have a history of diabetes or cardiovascular disease Consistent with prior publications, blacks had mean A1C values 0.

Nevertheless, race did not modify the association between the A1C value and adverse cardiovascular outcomes and death Because follow-up revealed that blacks with biochemically defined incident diabetes were significantly less likely than whites to report having received a diagnosis of diabetes by a physician, the authors speculate that delays in diagnosis may explain the higher A1C values in blacks.

The molecular mechanism underlying the racial and ethnic differences remains to be established. Possibilities include differences in rates of glucose uptake into erythrocytes, rates of intraerythrocytic glucose metabolism, rates of glucose attachment to or release from hemoglobin or erythrocyte life span 50 , Most factors that alter FPG do not significantly affect A1C concentrations.

Acute illness, short-term lifestyle changes e. The interpretation of A1C depends on the erythrocytes having a normal life span. Patients with hemolytic disease or other conditions with shortened erythrocyte survival have a substantial reduction in A1C Similarly, individuals with acute blood loss have spuriously low A1C values because of an increased fraction of young erythrocytes.

False increases in A1C have been reported with some methods in patients with hypertriglyceridemia, hyperbilirubinemia, uremia, chronic alcoholism, or chronic ingestion of salicylates Because most interferences are method specific, in many cases they can be overcome by selecting an appropriate method that is not subject to the interference.

Individuals with iron deficiency anemia have increased A1C and fructosamine concentrations 54 , both of which are reduced by therapy with iron 54 , A mechanism for the higher A1C was recently identified by the demonstration that malondialdehyde, which is increased in subjects with iron deficiency anemia 54 , augments glycation of hemoglobin However, the magnitude of the increase in A1C is probably small.

Examination of 10, adults without self-reported diabetes in NHANES III revealed that while Iron deficiency in women was associated with a small odds ratio 1. Nevertheless, it would seem prudent to correct the iron deficiency before measuring A1C in individuals with severe iron deficiency anemia.

The most widely used commercial methods use either antibodies immunoassays or cation-exchange chromatography most commonly high-performance liquid chromatography to separate the glycated A1C from the nonglycated hemoglobin The National Glycohemoglobin Standardization Program NGSP has been instrumental in standardizing A1C testing among laboratories 58 , 59 , particularly but not exclusively in the U.

The NGSP has markedly improved the performance of A1C testing In addition, the International Federation for Clinical Chemistry IFCC developed a reference method using mass spectrometry or capillary electrophoresis for A1C measurement, which should result in international harmonization as it facilitates traceability to a metrologically sound accuracy base.

It is important to emphasize that the IFCC method is technically complex, time consuming, and expensive and is not designed for routine analysis of patient samples. Hemoglobin variants affect some A1C measurements. The most common variants are HbS, HbE, HbC, and HbD.

A1C measurement is not appropriate in subjects homozygous for HbS or HbC, with HbSC or with any other variant that alters erythrocyte survival.

However, A1C can be measured accurately in individuals heterozygous for HbS, HbE, HbC, or HbD and in those with increased HbF, provided an appropriate assay is used 53 , In addition, if the sample is analyzed by high-performance liquid chromatography method, careful inspection of the chromatogram usually reveals the aberrant peaks produced by the variant hemoglobin.

In these situations, hemoglobin electrophoresis should be performed. It is important to emphasize that, like any other test, A1C results that are inconsistent with the clinical presentation should be investigated.

The requirement that the subject be fasting at the time the blood is drawn is a considerable inconvenience. While our ability to measure glucose has improved, inherent biological variability can produce very large differences within and among individuals.

In conjunction with lack of sample stability, which is difficult to overcome in clinical practice, these factors results in lack of reproducibility of glucose testing. A1C, which reflects chronic blood glucose values, is routinely used in monitoring glycemic control and guiding therapy.

The significant reduction in microvascular complications with lower A1C and the absence of sample lability, combined with several other advantages Table 3 , have led to the recommendation by some organizations that A1C be used for screening and diagnosis of diabetes 1.

Accumulating evidence suggests that racial differences in A1C values may be present, and the possible clinical significance of this needs to be determined. Importantly, A1C cannot be measured in certain conditions.

Despite these caveats, A1C can be measured accurately in the vast majority of people. A comprehension of the factors that influence A1C values and the conditions where it should not be used will produce accurate and clinically meaningful results.

The convenience of sampling at any time without regard to food ingestion makes it likely that measurement of A1C will result in the detection of many of the millions of people with diabetes who are currently undiagnosed.

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.

Find out how both blood tests give important insights into your health.	Keeping blood sugar levels on target is extremely important to prevent blood sugar drops and spikes that can lead to a variety of complications. For example, when your blood sugar drops too low, this can lead to hypoglycemia and when it gets too high it can lead to hyperglycemia and other complications. Experts recommend checking your A1C every three months when your blood sugar levels are not on target or when you are incorporating any new changes to diabetes management i. Once you are on target, A1C testing can happen every six months. Checking your blood sugar at home using a blood glucose monitor is a good way to ensure you are on track. The frequency of how often you should test depends on many factors such as:. If you have type 1 diabetes , your diabetes healthcare team may recommend testing as often as 4 to 10 times a day. For those living with type 2 diabetes the frequency will depend on your treatment plan but can range from testing a few times a week to several times a day. Your healthcare team will advise you on the most suitable testing frequency based on your individual situation. Checking A1C through your routine medical appointments and monitoring blood sugar levels in between these appointments are both important ways to assess how your diabetes management plan is working for you.
