Speciality
Endocrinology, Internal Medicine
Intended Use
This test measures the levels of glycosylated hemoglobin and is essentially a measure of blood glucose levels over a long period of time. The test is ordered in diabetic patients or patients suspected of diabetes.
Clinical Significance
Hemoglobin A1c (HbA1c) is a result of the nonenzymatic attachment of a hexose molecule to the N-terminal amino acid of the hemoglobin molecule. The attachment of the hexose molecule occurs continually over the entire life span of the erythrocyte and is de

Collection Instruction
Observe universal precautions when collecting a blood specimen.
Record the time of day when the blood test is drawn.
Follow the recommended order of draw when collecting blood in tubes.
To obtain valid results, do not fasten the tourniquet for longer than 1 minute. Release and remove the tourniquet as soon as possible after the blood begins to flow. Prolonged tourniquet application can cause stasis and hemoconcentration.
Wrap the tourniquet around the arm 3 to 4 inches (7.5 to 10.0 cm) above the venepuncture site. If a blood pressure cuff is used in place of a tourniquet, inflate it to no more than 40mm Hg.
The veins become more prominent and easier to enter when the patient forms fist. However, there must not be vigorous hand exercise (pumping) - vigorous hand pumping can cause changes in the concentration of certain analytes in the
blood.
The preferred venepuncture site is the antecubital fossa.
Mix additive tubes by inversion. Do not shake the blood specimen. Hemolysis may result from vigorous shaking and can invalidate test results. Use gentle inversions.
Collect the blood specimen from the arm without an intravenous (IV) device, if possible. IV infusion can influence test results.
Do not use the arm bearing a dialysis arteriovenous fistula for venepuncture unless the physician specifically authorizes it.
Because of the risk of cellulitis, do not take specimens from the side on which a mastectomy or axillary lymph node dissection was performed.
Rejection Criteria
Grossly hemolyzed samples, Quantity not sufficient, Mislabelled or Unlabelled specimens
