A1c test

The A1c test (or hemoglobin A1c or glycohemoglobin test) is a blood test that shows the average level of blood sugar (glucose) over the past 2 to 3 months. Most doctors think that this is the best way to check how well a person is managing their diabetes. The test may also be used to diagnose diabetes or prediabetes. This test may not be appropriate for everyone because many things can affect the life span of red blood cells, such as the second or third trimester of pregnancy, a recent blood loss or a blood transfusion, sickle cell disease, hemodialysis, or erythropoietin (ESA) medicine.

The A1c test result also can be used to find the estimated average glucose, or eAG. A1c and eAG show the same thing in two different ways. A1c is shown as a percentage, while eAG uses the same units (mg/dl) as a glucose meter.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
