Is the a1c test best for diagnosing diabetes? by vincent savarese, md, what is the a1c test? in the past, the standard diagnostic test for diabetes has been the fasting glucose test. however, the drawback of this test is that it requires the patient to fast for 12 hours. is this a new test? the a1c test has been around for a long time… The a1c test can be used to diagnose type 2 diabetes and prediabetes. 1 the a1c test is also the primary test used for diabetes management. an a1c test is a blood test that reflects your average blood glucose levels over the past 3 months.. One of the more controversial issues in diabetes today is the use of the a1c test to diagnose diabetes instead of the current standards of fasting plasma glucose (fpg – measures blood glucose after a 12-14 hour fast) or oral glucose tolerance tests (ogtt – blood glucose is measured after the patient consumes a standardized amount of glucose)..
The hemoglobin a1c test has long been considered the "gold standard" when it comes to diagnosing diabetes. specifically, an a1c level of 5.7% and higher indicates abnormally high blood glucose levels and corresponds to average blood glucose of 117 mg/dl. an a1c between 5.7% and 6.4% is dia. The glycated hemoglobin test (hba1c) or the a1c test has been around for more than 30 years. it provides average blood glucose over the previous 90 days. it has become the gold standard test in diabetes care. but, it has not been used as a way to diagnose a person with diabetes because it was not a standardized test.. The current gold standard for diabetes screening is the glycohemoglobin test (hba1c). it is a general gauge of diabetes control that specifies an average blood glucose level over a few months..
Long used in the management of diabetes, the a1c blood test measures average blood sugar levels for the previous two to three months. the new guidelines call for the diagnosis of type 2 diabetes at a1c levels above 6.5 percent, and prediabetes if the a1c levels are between 5.7 and 6.4 percent.. What is the a1c test? in the past, the standard diagnostic test for diabetes has been the fasting glucose test. however, the drawback of this test is that it requires the patient to fast for 12 hours. it also only reflects the patient’s blood glucose level at the time of testing—possibly missing some individuals who may have abnormal glucose levels. the a1c test stands for hemoglobin a1c..
