• Hemoglobin A1,
• Glycosylated hemoglobin
• Index of diabetes control,
An analysis of glycated hemoglobin shows the average level of sugar (glucose) in your blood in the last six to eight weeks.
Hemoglobin is a protein carried by red blood cells or red blood cells. The sugar from the blood binds to hemoglobin to form hemoglobin A1 (glycosylated).
If the blood contains more sugar and glycated hemoglobin increases on all that remains increased during 120 days. Therefore the measurement of glycated hemoglobin reflects the ups and downs of blood sugar in the last eight weeks or more.
Hemoglobin A1 is an average level of sugar in recent months, while a test for blood sugar (glucose) only tells you the status of their diabetes control at some point.
What is analysis?
It has many functions, including:
• Rate a treatment for diabetes, in terms of dosage or compliance.
• Compare treatments and patterns used
• Measuring increases in blood glucose in diabetic patients newly diagnosed
• Assess changes in blood glucose in mild diabetics
• Individualize treatment in diabetics
• Assessment of labile diabetes or large changes in blood glucose
• To differentiate hyperglycemia of diabetics from other acute causes (stress, heart attack).
Procedure For Obtaining
• To perform this analysis is not necessary to be fasting.
• It should be remembered that certain hemoglobinopathies can modify the results.
• Impossible to take an appropriate place (see, clinic, hospital) but sometimes is done in the patient's home.
• To make the taking is necessary to locate a suitable vein and the veins are generally used in the flexure of the elbow. The person taking the sample used medical gloves, a needle (with a syringe or tube removal).
• You will have a tortor (tape-rubber latex) in the arm to retain more blood veins and appear more visible and accessible.
• Clean the area with an antiseptic and puncture through a vein located palpation and appropriate access to it with the needle. We drop the tortor.
• When blood flows through the needle aspiration done on health (by syringe or by applying a vacuum tube).
• At the end of the shot, the needle is removed and the area is pressed with a cotton swab or something similar to promote clotting and you will be
asked to bend your arm and hold down the area with a plaster for a few hours.
• The blood is transferred to the laboratory for analysis on a special tube for biochemistry, a product containing anticoagulant. In general are not usually required more than 10 milliliters of blood for a battery of standard biochemical parameters.
Problems And Potential Risks
1. The acquisition by a puncture of the vein can cause some pain.
2. The potential difficulty in finding suitable vein can lead to multiple punctures.
3. Appearance of a hematoma (bruising or Cardinal) in the quarry area, usually due to the vein has not been closed or after the back pressure and has continued to produce blood coming out this problem. You can apply an ointment or type Hirudo ® ® Trombocid in the area.
4. Inflammation of the vein (phlebitis), sometimes the vein is altered, either by a purely physical cause or has been infected. The area should be kept relaxed few days and you can apply an ointment or type Hirudo ® ® Trombocid in the area. If the problem persists or fever should consult your doctor.
Normal value of glycated hemoglobin (HbA1)
Normal adults - 2.2 to 4.8%
Normal children - 1.8 to 4%
Well-controlled diabetic - 2.5 to 5.9%
Diabetics with adequate control - 6 to 8%
Poorly controlled diabetes - greater than 8%
These values may have some differences in technique or criteria of normality own laboratory, sometimes in the range of values, and sometimes units to which it refers.
Valuation Results Of Abnormal
Shown increased levels of glycated hemoglobin in:
• Diabetes mellitus
• Poorly controlled diabetes mellitus
• People without spleens
Shown decreased levels of glycosylated hemoglobin in:
• Hemolytic anemia
• Kidney disease
• Chronic blood loss
