In 1990, its primary mission over, Voyager 1 was instructed to point its camera at Earth, or the Pale Blue Dot, 6 billion kilometers away. VOYAGER 1 has been beaming data to Earth since 1977. But members of mission control at NASA's Jet Propulsion Laboratory (JPL), in Pasadena, California, are as excited as ever.
Cause of Elevated A1c Levels. The higher your blood sugar levels and the longer your blood sugar remains high, the more excess sugar is present in the blood and the more opportunities this excess sugar has to bond to hemoglobin.
The hemoglobin A1c test may be used to screen for and diagnose diabetes and prediabetes in adults. Hemoglobin A1c, also glycated hemoglobin or A1c, is formed in the blood when glucose attaches to hemoglobin. The higher the level of glucose in the blood, the more glycated hemoglobin is formed. Once the glucose binds to the hemoglobin, it remains there for the life of the red blood cell - normally about 120 days. The predominant form of glycated hemoglobin is referred to as A1c.
