Anyone showing the symptoms such as frequent urination, extreme thirst, and numbness or tingling in the hands or feet or who fall into one of the risk factors such as family history, overweight, or a specific ethnicity (African-American, Hispanic, Asian, Native American) should consider getting tested for diabetes. There are three tests a doctor will perform to test for diabetes. The first test is the A1C test. This test was recommended in 2009 by an international expert committee to be one of the tests to diagnose type 2 diabetes and prediabetes. The A1C test works by testing the way glucose attaches to hemoglobin. Hemoglobin is what carries oxygen in red blood cells. The typical life span of a red blood cell is three months. The A1C test will reveal the average glucose level over the past three months. The results of the tests are measured in percentages. The higher the percentage, the higher the glucose level. The normal percentage for the A1C test is 5.7%. Percentages from 5.7% to 6.4% indicate prediabetes and anything 6.5% and above indicates diabetes. The advantage this test has over other tests is that it does not require the patient to fast making it more convenient to come in to get tested for diabetes (Department of Health and Human Services, 2014).
The next two tests used for diagnosing diabetes are more traditional tests. The first is the fasting plasma glucose test (FPG). This test also determines the amount of glucose in the blood; however, it must be taken after a fasting period. Fasting means a person does not eat or drink anything for at least eight hours; to make this easier on the patient fasting is typically done overnight. The normal range for the fasting glucose test is below 100 mg/dl. A result measuring between 100 and 125 mg/dl is considered prediabetic and anything over 126 mg/dl is means the...
