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.
When blood sugar levels are high, the hemoglobin absorbs additional glucose, causing it to become glycosylated. A simple, non-fasting blood test, the hemoglobin A1c (glycosylated hemoglobin) level, can determine if glucose levels are consistently high over a period of weeks.reviously, fasting blood glucose levels or a glucose tolerance test were necessary for the diagnosis of diabetes, and some doctors still prefer to make the diagnosis based on a fasting blood glucose log over time. Glycosylated hemoglobin levels are predictive of complications of high blood glucose levels over time.
