Glycosylated hemoglobin in children | Revista Women's Health

If you have a young son with juvenile diabetes may be of the variety called type 1 diabetes or insulin-dependent diabetes as it is more common in young children, the second number of chronic disease affected after asthma.

While appearing recently are also many cases of type 2 diabetes in children and adolescents due to obesity, poor diet and lack of exercise.

So if you have a child with juvenile diabetes, you should be doing at least 7 daily checks of blood glucose to keep good control of their glucose values and establish patterns of insulin and / or power required to maintain the values blood glucose within normal ranges (normoglycemia).

But these controls you do every day can give you an idea of how blood glucose levels are at that time and whether or not to correct them so they can not offer is an overview to show you how the disease evolves and how it is being controlled, since these are point values and can fluctuate widely and quickly.

To check the status of glucose control (and thus, diabetes) in the long term, we need a test done with blood collected into a vein, no hair, and gives us the overall result of several weeks or months ( between 70 and 90 days).

That is the glycosylated hemoglobin test, also called glycosylated hemoglobin A1c.

What is glycosylated hemoglobin?

Hemoglobin is a protein found in red blood cells and is responsible for transporting oxygen throughout the body. Glucose, which as you know, it circulates in the blood, is capable of binding to this hemoglobin forming the so-called glycosylated hemoglobin.

Most of this is in a glycosylated form called A1c, which is easily measured, there are two types of hemoglobin are a1a and a1b, but which are present in a smaller amount. The more glucose in the blood, more glycosylated hemoglobin?is formed.

The life of hemoglobin is about 2 or 3 months, which is how long it stays in the blood. Therefore, if we measure the value of this glycohemoglobin have average glucose value during that period of 2 to 3 months. The values of glycated hemoglobin or glycosylated hemoglobin delivers you the laboratory, equal to the average blood glucose values for the last 3 months or so.

?I can I calculate it, too?

As I said at the beginning and you can infer from what you just said, you yourself can obtain the approximate value of glycosylated hemoglobin?(of course you will not get the same result as the analysis laboratory but you can serve to make an idea of how you keeping track of blood glucose).

To do this, as you have to go scoring daily blood glucose values that you make to your child, you can make a spreadsheet with these values and get the average value of the last 3 months (would be about 630 controls, 7 per day, say 210 per month).

Relationship between average glucose and glycosylated hemoglobin:

  1. Average glucose: 120 -> glycosylated hemoglobin: 6
  2. Average glucose: 150 -> glycosylated hemoglobin: 7
  3. Average glucose: 180 -> glycosylated hemoglobin: 8

Glycosylated hemoglobin values lying between 6 and 7 are pretty good for a diabetic child (in a healthy person would be between 4 and 5). Values up to 8 are acceptable, but from there, as they are dangerous and indicate poor control of diabetes, which can cause the onset of chronic complications and damage to other organs such as eyes and kidneys.

However, in pediatric patients (up to 6 years old or so), allowed values up to 8.5, but that is still very permissive. Have to ensure that the blood glucose levels are as long as possible within the acceptable range (ie greater than 60 and less than 180) and thus the glycosylated hemoglobin is not very high.

The control of glycosylated hemoglobin?is usually every 3 months, because as we have seen, each control gives the average blood glucose precisely this time, about 3 months ago.
