A1c is of particular interest because it is easy to detect. The process by which sugars attach to hemoglobin is called glycation and the reference system is based on HbA1c, defined as beta-N-1-deoxy fructosyl hemoglobin as component. [4] There are several ways to measure glycated hemoglobin, of which HbA1c (or simply A1c) is a standard single ...

Historically, blood glucose values were given in terms of whole blood, but most laboratories now measure and report plasma or serum glucose levels. Because red blood cells (erythrocytes) have a higher concentration of protein (e.g., hemoglobin) than serum, serum has a higher water content and consequently more dissolved glucose than does whole ...
In the blood, there is a molecule called hemoglobin which carries oxygen to the cells. Glucose can attach itself to this molecule and if the BG is consistently high, the value of the A1c will go up. This test, unlike the other tests, is measured as a percentage because the test measure the proportion of all the hemoglobin that has glucose attached.
The American Diabetes Association additionally recommends a diagnosis of diabetes for anyone with symptoms of hyperglycemia and blood sugar at any time at or above 11.1 mmol/L, or glycated hemoglobin (hemoglobin A1C) levels at or above 48 mmol/mol (6.5%). [46]
Prediabetes is a component of metabolic syndrome and is characterized by elevated blood sugar levels that fall below the threshold to diagnose diabetes mellitus.It usually does not cause symptoms but people with prediabetes often have obesity (especially abdominal or visceral obesity), dyslipidemia with high triglycerides and/or low HDL cholesterol, and hypertension.

Guinness Draught (4.2% ABV) Guinness, an Irish Dry Stout, is a fantastic example to disprove a common misconception, that dark beers are higher in alcohol.
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
