A1c 6.4 Questions

If you have prediabetes (i.e. an A1C score between 5.7 and 6.5 percent) you should check your A1C score once a year.

For people who have type 2 diabetes, check your A1C score twice a year if you don’t take insulin and your blood sugar level is consistently in target range, or check your A1C score four times a year if you use insulin to manage your diabetes and your blood sugar level is not consistently within the target range.

A1C scores are accurate up to .5%, so if you’ve scored a 6.89 percent, your actual score can be anywhere between 6.39 percent and a 7.39 percent. This is why doctors will test your A1C score twice before diagnosing you with diabetes – they want to make sure the reading is accurate.

There are a few common reasons why your A1C score will have errors or misreadings.

  • A1C tests for patients who experience chronic bleeding may yield a false low.
  • A1C tests for patients who have iron deficiency anemia may yield a false high.
  • If your body produces a form of hemoglobin variant different than the normal hemoglobin A, your test can be inaccurate. This is more likely for people of African, Southeast Asian or Mediterranean descent. An example of hemoglobin variant is present in people with sickle cell disease, which changes the lifespan of red blood cells.
  • Patients who are going through hemodialysis might have false lows because the processes may be filtering the glucose out of the patient’s bloodstream.
  • Patients who have had a recent blood loss due to surgery or a heavy menstrual cycle may experience a false low.
  • Liver disease, sickle cell anemia and kidney failure can cause your reading to be inaccurate.

Additionally, your A1C percentage can be off by as much as half a percent based on the margin of error. While that might mean the difference between being diabetic and prediabetic, if you’re a half a percentage away from developing diabetes or prediabetes, you should make changes to your lifestyle to reduce your score.

A chronic disease is one that lasts for more than three months, and according to the National Institute for Health and Care Excellence, people with chronic physical health problems are three times more likely to have depression. Unfortunately, diabetes is a chronic disease. The complications associated with diabetes serve as triggers for depression. For that reason, people who have diabetes are more likely to have depression.

The Department of Transportation doesn’t have diabetes regulations for personal drivers licenses; however, the department does regulate commercial driver’s licenses. Part of the DoT’s Physical Qualifications and Examinations, people who have diabetes are not physically qualified to have a commercial driver’s license. Therefore, drivers must submit an exemption form through the Federal Diabetes Exemption Program in order to obtain a commercial driver’s license if they have diabetes.

Other commercial drivers with diabetes who take insulin must apply for an exemption from the Federal Motor Carrier Safety Administration. These exemptions are good for a maximum of two years. The administration requires that people with exemptions go through quarterly and annual medical monitoring and reporting in order to maintain the exemption from the Federal diabetes standard.

Insulin users must also participate in diabetes education programs every year to continue to participate in the exemption program. They must also be evaluated by a board-certified or board-eligible Endocrinologist to confirm that no medical problems related to diabetes will impair safe driving. These examinations are valid for 6 months and must be renewed if expired during the application process, which is relevant because the application can take up to 180 days to process.

People with A1C scores that are greater than 10 are not eligible for the exemption and cannot get a commercial driver’s license.

There are home tests that you can purchase at your local pharmacy. They typically cost about half of what a hospital test costs and use a smaller amount of blood. Many at home kits have been cleared by the FDA and meet the standards of the National Glycohemoglobin Standardization Program for measuring A1C. There are multiple brands available like CVS, Walgreens and others.
