Final answer:
Hemoglobin A1c (HbA1c) is a key test for monitoring long-term blood sugar levels in individuals with diabetes.
Step-by-step explanation:
The test for Hemoglobin A1c (HbA1c), also known as glycosylated or glucosylated hemoglobin, is used to monitor the long-term control of diabetes mellitus. This specific type of hemoglobin has glucose bound to it, which reflects the average blood glucose levels over the past two to three months.
The HbA1c level is essential for diabetes management because it provides an indication of how well blood sugar is being controlled over time without being affected by short-term fluctuations due to meals.
The method used to measure HbA1c is called high pressure (or performance) liquid chromatography (HPLC), which separates the glycohemoglobin based on size and electrical charge from other components in the blood.
Since HbA1c is not influenced by daily glucose concentration changes, it's an effective way to monitor diabetes management but cannot be used for adjusting insulin doses on a day-to-day basis or detecting daily episodes of hyperglycemia or hypoglycemia.
It is measured using high pressure liquid chromatography (HPLC) and is unaffected by daily fluctuations in blood glucose, making it a reliable indicator of average blood sugar over several months.
