What is the A1C hemoglobin test?
The
Hemoglobin A1C (A1C) test is the level of blood sugar, which is more reliable than a standard finger test performed at home, using a blood sugar meter. Hemoglobin is the main protein in red blood cells and carries oxygen throughout the body. If the sugar level is high in the blood, it will bind to hemoglobin. This forms glycated hemoglobin , which is detected by the laboratory test of hemoglobin A1C. This reading provides blood sugar measurements that help diagnose diabetes mellitus or help patients determine how well they keep blood sugar levels under control.
Although diabetic patients permanently monitor blood glucose levels at home by means of a level meter level level level level level level level levels in the blood. These levels often fluctuate throughout the day. It is difficult to obtain an accurate estimate of the total blood sugar levels using this technique. The Hemoglobin A1C test provides a reliable level of blood sugar levels above the last three months,Which is an approximate life of the red blood cell.
As soon as sugar binds to hemoglobin, it remains tied. Because it measures the amount of glycated hemoglobin in red blood cells, the Hemoglobin A1C test provides an estimate of blood sugar levels in the previous months. Reading between 4 to 6% is considered normal. The levels of 6.5 to 7% indicate diagnosis of diabetes.
It could be expected that low levels from the hemoglobin A1C test would be considered healthy for diabetics, but it may not be the case. Diabetics fight high blood sugar, but there may also be a problem with low blood sugar - hypoglycemia. This is especially true for type 1 diabetics who have to insert insulin or type II diabetics on certain medicines. The extreme level of hypoglycaemia can cause loss of consciousness and death. It is possible that low hemoglobin reflects 1C tests indicate a combination of high glucose and hypoglycaemia incidents.
It is considered desirable for diabetics to have hemoglobin levels under 6.5%. This correlates with a reduced degree of complications from diabetes such as blindness, kidney problems, cardiovascular problems, gangrene and loss of feeling in the legs. The patient should consult with his doctor to determine the ideal target range that minimizes high blood sugar without causing hypoglycaemia.
There are certain individuals for whom the A1C hemoglobin test is not recommended. People with certain types of anemia, such as hemolytic and sickle cell, degrade their blood cells. In other words, red blood cells do not live for three months. Also, people with vitamin 12 or folic acid deficiency have blood cells that live much longer than usual. Individuals with these conditions are recommended not to use this method of measuring their long -term blood sugar levels.
there is an alternative test for measuring fructosamine levels that is sometimes used instead of a hemoglobin test A1C in patients who inThey are like a patient with hemolytic anemia. Unfortunately, it measures blood sugar from the last two to three weeks. This test measures the reaction of blood glucose with blood proteins such as albumin. One such test is known as the glycated albumin test .
