If you have diabetes, you might have heard your doctor or healthcare professional mention estimated average glucose (eAG).

But, what exactly is eAG, what does it tell you about your blood sugar levels, and why’s it important?

This article will help answer these questions and explain why it’s helpful to know what your eAG is if you have diabetes.

估计的平均葡萄糖（EAG）是指过去60至90天的平均血糖（葡萄糖）水平。可以在每分毫克（mg/dl）或毫米（mmol/l）中以毫克报告。

要测量您的EAG，您需要服用A1C blood test。

Unlike your dailyblood glucose readingsthat measure your blood sugar level at that moment, eAG looks at the bigger picture. Your eAG measures your typical blood sugar level over the past few months.

了解您的EAG可以帮助糖尿病管理的以下方面：

  • diagnosing both糖尿病and diabetes
  • 佐证每日血糖监测结果
  • determining whether your diabetes treatment plan is helping
  • 改变糖尿病治疗计划
  • 加强healthy lifestyle and diet选择

一旦知道了A1C百分比，就可以使用以下图表查找您的EAG：

A1C（％） EAG（mg/dl） EAG（mmol/l）
4 68 3.8
5 97 5.4
6 126 7.0
7 154 8.6
8 183 10.1
9 212 11。8
10 240 13.4
11 269 14.9
12 298 16.5

Alternatively, you can use this在线计算器from the American Diabetes Association (ADA) to determine your eAG using your A1C and vice versa.

这re’s a direct relationship between A1C and eAG values, as represented by the following formula:

EAG（mg/dl）= 28.7 x A1C - 46.7

通常，A1C和EAG读数都提供有关您最近血糖水平的相同信息，例如，您是否是您的治疗计划is helping.

但是EAG使用了您在每日血糖读数上经常看到的相同单元（mg/dl或mmol/l），从而更容易解释。

这re’s no single eAG target for everyone. Your doctor will help you determine an appropriate target according to your age and circumstances. In addition, your target eAG may change over time.

通常，鼓励大多数非怀孕的糖尿病成年人保持低于154 mg/dl（8.6 mmol/l）的EAG。这对应于不到7％的A1C测试结果。

这艾达定义以下EAG范围：

  • Normal range:小于114 mg/dl
  • 糖尿病范围：greater than 114 mg/dL and less than 140 mg/dL
  • 糖尿病范围：大于140 mg/dl

如上所示,更高的坚毅不屈值指示进行her average blood glucose levels over the past few months. If you’re in the prediabetes or diabetes range, you may be at an increased risk of developing diabetes并发症。

如果您的EAG价值高于目标，则可能是改善您的个性化治疗计划的机会。

重要的是要与您的医生或医疗保健专业人员谈谈您认为正在工作的事情，而无效的事很重要。然后，您的医生可以根据需要对您的计划进行更改。

According to the2021糖尿病护理指南provided by the ADA, people with well-controlled diabetes should undergo an A1C blood test to determine their eAG at least twice per year.

相同的指南建议对最近发生的治疗计划发生变化的个人至少进行4次测试，以及那些难以实现血糖靶标的人。

每日葡萄糖监测是另一个关键工具糖尿病管理。但是，每日监测并不能长期看到血糖水平。

这readings on your monitor provide a snapshot of your blood sugar at a particular point in time. Your monitor might automatically calculate an average of all of these readings. But this number isn’t the same as your eAG.

Your eAG accounts for your blood glucose levels 24 hours per day, including the times when you’re not likely to test. As the name suggests, it’s an estimate based on yourA1C test results。

如果您患有糖尿病，通常会指示您在低血糖时（例如，醒来，饭前或饭后几个小时）测试。您的EAG可能高于显示器上的平均水平，从而更广泛地了解您的血糖水平。

Your eAG can help both you and your healthcare team understand your blood glucose levels over a 60- or 90-day period.

要了解您的EAG，您必须接受A1C血液检查。您的EAG以与您通常在血糖计上相同的单位报告，从而简单地解释。

你的医生会帮助你确定一个合适的eAG target based on your age and additional factors. Depending on your eAG reading, your doctor may make changes to your diabetes treatment plan.
