The concentration of glucose in blood is the blood glucose level; you can measure it and there is need for maintaining the normal range. The blood glucose normal levels should be in a range of 4 to 6mmol/L. It is important to maintain this level as very high or very low levels may cause some other health problems and diseases and in extreme cases may even lead to severe complications. Typically doctors may advice you to maintain certain blood glucose levels considered normal if you are diabetic or a non-diabetic which would be safe for you.
The glucose levels are lower in the morning before your first meals. They maintain a range of 80mg/dL to 150mg/dLi.e. 3.9 to 8.3mmol/L. Temporarily the level may rise to 150mg/dL after your meals. You may have low blood sugar or hypoglycemia if you have chronic blood glucose levels below 70mg/dL. It is indicative of hyperglycemia or high blood sugar if the levels go beyond 150. You must consult the doctors to confirm the results though it need not necessarily be diabetes every time. Very high or very low levels of blood glucose is harmful for your body. While high level can cause damage to nerves, kidneys, low blood glucose levels may cause interfere with brains funtioning. Thus the importance of keeping your blood glucose within normal levels has to be well understood.
Blood glucose test and their normal ranges
There are different types of tests that can be conducted to find out if the blood glucose normal levels have been maintained. Generally each test shows a normal range. It may differ a bit from one lab test to another test.
Fasting blood glucose test: Blood Samples are take after eight hours of fasting. You fast for this time without having any food or liquids and can take only water. The blood glucose normal level for this test is less than 110mg/dL. It may be an indicator of diabetes if the reading is more than 126mg/dL after two consecutive blood tests.
Postprandial test: The postprandial test is conducted 2 hours after meal. For this normal level is under 120mg/dL. Many often this level goes below 100mg/dL or 5.5 among non diabetics after two hours.
* Random blood glucose test: The random test as the name suggest is taken at any time and not necessarily after a meal or snack. The normal range for this must not be higher than 200mg/dL or 11.1mmol/L.
* Oral glucose tolerance test: The oral test is conducted to measure your body’s response to sugar. The two steps are measuring your fasting blood sugar first and then drinking a sugary solution. Again the glucose level is measured after two hours. For this test the level should be also below than 140mg/dL or 7.This is 8mmol/L.
To control on diabetes over a period of time glycated hemoglobin test is useful for your measurement. It is a mirror of your average blood sugar for the last three to five weeks. It shows that how much percentage of your hemoglobin is effected with sugar. The normal levels are 4 to 6 percent in non diabetes and lower than 7 percent amongst diabetics. During pregnancy it should be lower than 6 percent.
Parents should check for normal blood glucose levels of their children to prevent them to suffer from the bad effects of high or low blood glucose levels. For do not have to face the complications as a result of the high or low levels diabetics as well as normal people should ensure that they maintain their blood glucose levels in the normal range.
