WebGlycated hemoglobin, also called hemoglobin A1c, HbA1c, A1c, or Hb1c, is a form of hemoglobin that is measured primarily to know the average plasma glucose concentration over a three-month period. It is limited to a three-month average because the lifespan of a red blood cell is four months. WebHemoglobin is a conjugated chromo-protein having heme as its prosthetic group. Heme is the prosthetic group, not only of hemoglobin but also of myoglobin, cytochromes etc. Hemoglobin is formed by the combination of heme with globin (protein).
