Glycated hemoglobin (HbA1C) is a strong marker for diabetic control measurements, reflecting average blood glucose levels over the past 3-4 months. This test is affected by many factors and diseases. The objective of this study is to assess the value of glycated hemoglobin in type 2 diabetic mellitus for metabolic syndrome. Most diabetic patients have raised hemoglobin A1c, that is considered to be an important factor in the control of blood sugar levels and the pharmacological efficacy of medicinal products which will never be affected by latest diets as well as treatments. The findings showed that the majority (%) of patients avoided a diabetic control HbA1c level test. High blood pressure (systolic or diastolic) was identified as a significant risk to patients. The mean value of glycated hemoglobin was 8.76%. Hemoglobin A1c > 7% Patients with had markedly increased fasting glucose levels compared to those with HbA1c < 7%. Identifying the level of HbA1c is easier.
