THURSDAY, Aug. 21, 2014 (HealthDay News) -- The U.S. Food and Drug Administration has approved a new test that may help doctors diagnose type 1 diabetes, the most common form diagnosed in children and adolescents.

The Kronus ZnT8Ab Elisa Assay may help some people with type 1 diabetes receive faster diagnosis and treatment, the FDA said in a news release. People with type 1 diabetes produce little or no insulin because cells in the pancreas that produce the hormone are mistakenly attacked by the body's immune system.

Insulin is a hormone that converts sugars (glucose) in food to fuel for the body. People who lack the hormone must inject insulin to regulate blood glucose and lower their risk of potential complications, including blindness, kidney failure and heart disease.

The test was able to diagnose a key marker in 65 percent of samples from people diagnosed with type 1 diabetes, and incorrectly gave a positive result in less than 2 percent of samples, the FDA said.

On the other hand, the agency stressed that negative test result should not rule out a diagnosis of type 1 diabetes. The test also shouldn't be used to monitor the body's response to treatment, the FDA added.

The new test is produced by Kronus Market Development Associates, based in Star, Idaho.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
