Diabetes Classification for PreViser™

To calculate risk scores, PreViser™ uses the following standards to classify the patient’s diabetic condition. This applies to both type 1 and type 2 diabetes, and is based on the level of glycemic control. You are asked to indicate the level of diabetic control as Good, Fair, or Poor.
 

Questions to Ask the Patient

You can respond to this question properly by asking your patient the following questions:

1. What is your blood glucose (blood sugar) level? (measured with a A1C test within the last six months)
  • "Good" control is less than 6.5
  • "Fair" control is 6.5 to 7.5
  • "Poor" control is greater than 7.5

2. What is your average fasting blood sugar? (measured during the last month)
  • "Good" control is between 90 and 104
  • "Fair" control is between 105 and 130
  • "Poor" control is greater than 130
 

PreViser™ values for the diabetic status are:

Measurement Good control Fair control Poor control
HbA1c (%) <6.5 6.5-7.5 >7.5
AM Fasting plasma glucose (mg/dl) 90-104 105-130 >130
 

“GHb” (also called glycated haemoglobin, glycohaemoglobin, glycosylated haemoglobin, HbA1c, or HbA1) most accurately indicates the previous two to three months of glycemic control. Two glycated haemoglobin tests are available: the haemoglobin A1 (HbA1) test and the haemoglobin A1c (HbA1c) test. The A1c test is quite common, so your patient may be familiar with that term.

Good control means getting as close to a normal (nondiabetic) blood glucose level as the individual safely can. Ideally, this means levels between 90 and 130 mg/dl before meals, and less than 180 two hours after starting a meal, with a glycated haemoglobin level less than 7 percent.

In discussing these levels with your patients, it is critical to know whether their home monitor and test strips measure results in terms of whole blood or plasma values, because the plasma glucose values are 10-15% higher than whole blood glucose values.
