HbA1c was measured using high-performance liquid chromatography based on the National Glycohemoglobin Standardization Program-certified PDQ Primus guidelines.
Women with gestational diabetes mellitus, pregestational diabetes, anemia, a pregestational BMI < 18.5 or ≥ 25 kg/m 2, and any hematologic, hepatic, immunological, renal, or cardiac disease were excluded. This cross-sectional study included healthy Mexican pregnant women in trimester 1 (T1), 6–13.6 weeks of gestation (WG), trimester 2 (T2), 14–27 WG, and trimester 3 (T3), ≥27–36 WG, with a maternal age > 18 years, and pregestational body mass index (BMI) ranging between 18.5–24.9 kg/m 2. The study aims to determine the reference intervals for HbA1c at each trimester in healthy Mexican pregnant women. Keeping your A1c level in your target range can lower your chance for problems.The reference intervals for hemoglobin A1c (HbA1c) in pregnant Mexican women without diabetes are not well defined. The A1c test can also help your doctor see how big your risk is of developing problems from diabetes, such as kidney failure, vision problems, and leg or foot numbness. This test may not be accurate 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. This test shows how well your diabetes has been controlled in the last 2 to 3 months and whether your diabetes treatment plan needs to be changed. Since red blood cells last 3 to 4 months, the A1c test shows how much glucose is in the plasma part of blood. Glucose binds to hemoglobin in red blood cells at a steady rate. The A1c test result does not change with any recent changes in diet, exercise, or medicines. It is useful for a person who has diabetes to have information about the long-term control of blood sugar levels. Blood glucose levels change during the day for many reasons, including medicine, diet, exercise, and the level of insulin in the blood. Sometimes an A1c test can be done with blood from a finger stick.Ī home blood glucose test measures the level of blood glucose only at that moment. This test can be done with a blood draw from a vein.
Most doctors think checking an A1c level is the best way to check how well a treatment plan is working. The A1c test checks the long-term control of blood glucose levels in people with diabetes.
People who have diabetes or other conditions that increase their blood glucose levels have more glycohemoglobin (sugar bound to hemoglobin) than normal.Īn A1c test can be used to diagnose prediabetes or diabetes. A glycohemoglobin test, or hemoglobin A1c, is a blood test that checks the amount of sugar (glucose) bound to the hemoglobin in the red blood cells.
