HbA1c Measurement

A haemoglobin A1C (HbA1C) test is a blood test that shows what your average blood sugar (glucose) level was over the past two to three months.The term HbA1c refers to glycated haemoglobin. It develops when haemoglobin joins with glucose in the blood, becoming ‘glycated’. The amount of glucose that combines with haemoglobin is directly proportional to the total amount of sugar that is in your system at that time. Therefore, by measuring glycated haemoglobin (HbA1c), we can get an overall picture of what a person’s average blood sugar levels have been over a period of approx. 2-3 months.

Limitations of HbA1c testing

For the vast majority of patients with diabetes, HbA1c provides an excellent measure of glycemic control. However, there are situations where HbA1c may be unreliable. These include any condition that alters the erythrocyte life span (e.g., hemolytic anemia), severe iron-deficiency anemia, and certain hemoglobin variants or adducts, or recent red blood cell transfusions. Factors such as race or age are also reported to influence HbA1c.

 What is it used for?

An A1C test may be used to screen for or diagnose:

  • Type 2 diabetes. With type 2 diabetes your blood glucose gets too high because your body doesn’t make enough insulin to move blood sugar from your bloodstream into your cells, or because your cells stop responding to insulin.
  • Prediabetes. Prediabetes means that your blood glucose levels are higher than normal, but not high enough to be diagnosed as diabetes. Lifestyle changes, such as healthy eating and exercise, may help delay or prevent prediabetes from becoming type 2 diabetes.

If you have diabetes or prediabetes, an A1C test can help monitor your condition and check how well you’ve been able to control your blood sugar levels.

 

What is a normal pulse rate?

Your pulse rate, also known as your heart rate, is the number of times your heart beats per minute. A normal resting heart rate should be between 60 to 100 beats per minute, but it can vary from minute to minute.

Your age and general health can also affect your pulse rate, so it’s important to remember that a ‘normal’ pulse can vary from person to person.

Your heart rhythm: as regular as possible

Your heart rhythm is the rhythm at which your heart beats. It will learn whether those beats come regularly (or not). Suppose you have a heart rate of 80, then your heart should beat every 0,75 seconds.

Your heart rate varies constantly. But your heart rhythm should remain regular throughout the day.

An irregular heart rhythm is what we call a heart rhythm disorder. Occasionally your heart can skip a beat, this is called an ectopic beat. Or your heartbeats follow each other rapidly during a short period of time and then slow down again.

An example to make it clear. This graph shows the same heart rate twice.

  • The rhythm in the top line is regular. Each heartbeat is equally far apart, all peaks are equally high and wide (this is the so-called sinus rhythm).
  • The second rhythm is irregular. In the beginning 3 heartbeats follow each other very quickly, between the last 2 heartbeats more time passes.

In both cases, the heart beats 60 times per minute. Although the heart rate is the same, that cannot be said about the heart rhythm.
