Diabetes Screening (HbA1C & Fasting Sugar)

A Diabetes Screening (HbA1C & Fasting Sugar) test includes two blood tests, namely fasting blood sugar level and glycosylated hemoglobin (HbA1c), that help estimate your blood sugar levels, assess your risk of developing diabetes, and monitor its treatment progress. This test is often done as part of a routine health checkup.

Diabetes is a chronic condition that affects the body’s ability to process blood sugar. If left untreated, it can lead to a range of health conditions. The signs and symptoms of diabetes include increased thirst, frequent urination, blurred vision, fatigue, and slow healing of wounds. However, some individuals with diabetes may not experience any symptoms at all.

A Diabetes Screening (HbA1C & Fasting Sugar) test combines fasting blood glucose and glycosylated hemoglobin tests. A fasting blood sugar test helps measure the blood sugar levels after an overnight fasting state, while glycosylated hemoglobin measures the average blood sugar levels over a period of 2 to 3 months. 

Your doctor may suggest a Diabetes Screening (HbA1C & Fasting Sugar) test if you show symptoms suggestive of diabetes, such as nerve damage, vision problems, heart disease, chronic kidney disease, etc. Furthermore, this test is also used to monitor the progress of individuals undergoing diabetes treatment.

Usually, overnight fasting (8 to 12 hours) is preferred before a diabetes screening test. Do not eat or drink anything except water before the test. It is also essential to inform the doctor about any medicines you are taking, as some may affect blood glucose levels and need to be adjusted or temporarily discontinued before the test. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them evaluate your medical condition and formulate an overall treatment plan.
