Syncope
Syncope is a synonym for fainting or passing out. Someone is considered to have syncope if they become unconscious and go limp, then soon recover.
A1C
a1c
A1C, also known as hemoglobin A1C or HbA1c, is a blood test that measures the average level of blood glucose (sugar) over the past two to three months. The test determines what percentage of hemoglobin, the protein in red blood cells that carries oxygen, is coated with sugar, reflecting how well blood sugar has been controlled over this period.
Purpose and Use
-
The A1C test is widely used to diagnose prediabetes and diabetes, as well as to monitor how well someone with diabetes is managing their condition.
-
It is especially valuable because it gives a long-term picture of blood sugar levels, unlike daily blood glucose checks, which offer only a snapshot.
How It Works
-
When glucose enters the bloodstream, it attaches to hemoglobin in red blood cells; since these cells live about three months, the A1C result shows the average blood sugar level during that timeframe.
-
Higher A1C levels indicate higher average blood sugar and thus a greater risk for complications of diabetes.
Test Numbers
-
A normal A1C level is below 5.7 percent.
-
Levels between 5.7 and 6.4 percent indicate prediabetes.
-
An A1C level of 6.5 percent or higher on two separate tests suggests diabetes.
This test is a crucial tool for both diagnosis and ongoing management of diabetes and prediabetes
