Appropriate Sample Collection Tube for Hemoglobin A1C Test
Hemoglobin A1C test measures the amount of blood glucose attached to hemoglobin. As hemoglobin is part of our red cells, hemoglobin A1C test can only be determined from a whole blood specimen that contains red blood cells. Specimen for Hemoglobin A1C is collected with the #Levander top #EDTA test tube. It produces abnormally low result if specimen is collected with SST (golden-top) test tube, which causes the blood to clot quickly and allows only the serum for testing.

We may ask your patients for another appropriately collected sample if specimen is collected with tubes other than EDTA.
