ERC stands for erythrocyte count (red blood cell count). It tells you the the number of RBCs that are present in blood. Low values are indicative of anemia. ERC is also closely related to hemoglobin (Hgb) and hematocrit (Hct) levels; if the ERC is low then Hbg and Hct will most likely be low.
Glycohemoglobin (A1c) is a blood test that checks the amount of sugar (glucose) bound to the hemoglobin in the red blood cells. When hemoglobin and glucose bond, a coat of sugar forms on the hemoglobin. That coat gets thicker when there's more sugar in the blood.
