Normal blood glucose level chart handy a guide to monitor glucose levels

Diabetes management involves regular monitoring of blood glucose levels. If you are suffering from hyperglycemia or diabetes you should check if your glucose levels are in the normal acceptable or safe range. Prepare a normal blood glucose level chart which can prove to be really handy to compare the levels every time you test the glucose levels. By maintaining a chart on paper or in a worksheet will enable you to analyze the effect of medication, diet and exercises and the effectiveness of your control plan.

Normal blood glucose level chart

The American Diabetes Association has provided some guidelines for normal and abnormal glucose levels. Your doctor may set slightly different target ranges considering your overall health. Children may have a slightly higher target ranges. Similarly adults starting on insulin may also be given a different range.

* Morning fasting glucose levels advisable for non-diabetics are between 70 to 99mg/dL. However, for diabetics the range of 90-130 for adults and 90-140 for children.
* 2 to 4 hours after meals the glucose levels for non diabetics should be in the range of 70-139mg/dL. Among diabetics it should be less than 180mg/dL.
* Before bedtime glucose level should be 140-160mg/dL among adults and higher but not more than 180mg/dL in children.
* Blood glucose level less than 70mg/dL are indicative of hypoglycemia.
* Readings of 200mg/dL or higher are pointers to diabetes.

The American Diabetes Association provides guidelines to interpret the reading of the different tests like fasting blood glucose (FBG), Oral Glucose Tolerance Test (OGT) etc.

The fasting glucose test:
* A normal range of 70 to 99mg/dL or 3.9 to 5.5mmol/L is necessary for non diabetics.
* Readings between 100 to 125mg/dL or 5.6 to 6.9mmol/L indicate pre-diabetes or impaired fasting glucose (IGF)
* Levels of 126mg/dL i.e. 7.0mmol/L or higher may be diagnosed as Diabetes after confirmation using some more tests.

Oral glucose tolerance test
Sometimes glucose levels are higher than normal but lower than the diabetic range. An oral glucose tolerance test can be done to check levels 2 hours after consuming 75grams of glucose from a sugary drink.
* If the level is less than 140mg/dL or 7.8mmol/L after 2 hours after drinking then it indicates normal glucose tolerance.
* When readings are 140 to 200mg/dL or 7.8 to 11.1mmol/L it indicates impaired glucose tolerance or pre-diabetes. There is a higher risk of diabetes in such cases.
* Levels over 200mg/dL or 11.1mmol/L on one or more occasion would mostly be diagnosed as diabetes.

Gestational diabetes screening:

Glucose Challenge Test
The glucose challenge test helps find if you are suffering from gestational diabetes.1 hour after drinking 50grams of glucose if the level is less than 140mg/dl it indicates normal glucose tolerance and more than 140mg/dL means levels are abnormally elevated and the woman needs to take an Oral glucose tolerance test (OGTT).

Oral glucose tolerance test during pregnancy
Levels below 95mg/dL or 5.3mmol/L or lower after fasting i.e. before glucose load are normal levels. One hour after glucose load normal level means less than 180mg/dL or 10mmol/L. The normal level after two hours should be 155mg/dL or lower and after 3 hours it should be 140mg/dL or 7.8mmol/L or lower.

The ranges mentioned here are according to the guidelines provided by ADA as preferable normal levels and are intended for general purpose. The levels advised by the doctor may vary to a certain extent depending on your medical needs.
