Blood glucose levels indicate the glucose amount that a person has in their blood. Having low or high blood sugar levels may be an indication of underlying health conditions that might necessitate medical attention.
Blood sugar levels are often low, high, or normal, which will depend on the amount of glucose the person has in their blood at any given time. Glucose is one of the simple sugars and is always present in your bloodstream. Normal blood glucose levels are typically measured when a person eats, fasts, or directly after they have eaten.
A normal level in adults that do not suffer from diabetes, and have not eaten for the last 8 hours (fasting), is under 100mg/dL. Normal blood glucose levels in adults that do not suffer from diabetes, 2 hours after they have eaten should be 90 to 110mg/dL.
What Is A Blood Glucose Test?
There are currently two methods used to measure a person’s blood glucose levels:
Blood Sugar Test
This test is used to measure current levels of glucose present in the bloodstream. It is possible to test your blood sugar levels using either a continuous glucose monitor or a blood-sugar meter.
The continuous glucose monitors involve a sensor that measures blood sugar levels. A health practitioner inserts this sensor directly under your skin, typically in your arm or abdomen. The sensor then transmits information onto a monitor which displays your glucose levels.
The blood sugar meters measure the glucose levels in your blood through a small amount of blood (usually one drop) from your finger.
This test is used to measure the approximate glucose levels in the blood over the last 2 to 3 months. These tests are conducted in a lab. The A1C test is used to measure a percentage of the glucose-bound hemoglobin in your blood. The NIH (National Institutes of Health) states that this test provides an overview of the patient’s glucose levels for the last 2 to 3 months.
An abnormal AC1 test result is not always an indication that the patient has diabetes. If your test does come back abnormal your doctor will conduct more tests with other blood glucose tests. Your doctor will probably recommend running additional tests which usually include blood work in order to rule out any other conditions which may be affecting your blood sugar levels.
When Should You Get An A1C Blood Sugar Test?
The CDC has recommended that people that already have diabetes should be going for an A1C test every 6 months. Doctors use the A1C results to determine and monitor whether the person is responding to a glucose-management regime. Doctors also often use the A1C test in order to diagnose both diabetes and prediabetes.
Obtaining medical advice and recommendations from healthcare providers such as endocrinologists is one of the best methods to establish if you have normal blood glucose levels or not. Failing to get the correct treatment for either high or low blood sugar levels could lead to serious health complications, particularly for anyone with diabetes.
If you book an appointment with a doctor to have your blood sugar levels tested, you will be asked questions about your level of exercise, your diet, and your medical and family history. Some doctors may request blood samples to analyze your sugar levels. They may also request an A1C test, that measures your average blood sugar levels over 2 to 3 months. You may be asked to fast for at least 8 hours before your test to obtain an accurate test result.
