Understanding The Numbers

Fasting blood sugar or FBS is a test for the levels of glucose in blood. Glucose is the major monosaccharide in blood. Its measurement is important to the diagnosis of diabetes mellitus. Fasting, because the patient has to fast for 8-12 hours prior to testing.  Fasting is essential to come up with reliable laboratory resultsand consequently — diagnosis.

A fasting blood sugar (FBS) level is one test  among the tests used to diagnose diabetes mellitus (an additional becoming the oral glucose tolerance test ). In an individual with symptoms of osmotic diuresis and an elevated fasting blood sugar level, the diagnosis of diabetes mellitus is usually created.

The fasting blood sugar is determined by taking a sample of venous blood following an overnight fasting.

How will be the fasting blood sugar test performed? The American Diabetes Association recommends that the fasting blood sugar test be administered in the morning because afternoon tests tend to give lower readings. It is also generally more convenient to take the test within the morning because you must fast for a minimum of 8 hours beforehand.

The fasting blood sugar test consists of a simple blood draw, which is sent to your doctor’s lab for analysis. Though most doctors will tell you any fasting blood sugar under 100 mg/dl (five.6 mmol/L) is “normal”, there are a number of studies that suggest that testing having a fasting blood sugar within the mid 90 mg/dl (5 mmol/L) range frequently predicts diabetes that is diagnosed a decade later.

The value most of us would find a lot more helpful in assessing our health is not fasting blood sugar but some thing else: the number of hours each day our blood sugar spends elevated over the level known to cause complications, which is roughly 140 mg/dl (7.7 mmol/L).

Doctors have for decades relied on the FPG (fasting plasma glucose) test which measures fasting blood sugar to diagnose diabetes. The reason for this isn’t that FPG test results predict diabetic complications. They don’t. Post-meal blood sugar tests are a much better indicator of whether or not a person will get the classic diabetic complications, and also the A1c test is really a much better indicator of potential heart illness.
