About the Test

This is a single-marker test measuring hemoglobin A1c.

Ordering The Hemoglobin A1c (HbA1c) with ZRT

The hemoglobin A1C (HbA1C) test is a blood test that shows what the average glucose level was over the past two to three months.

Glucose is a type of sugar in the blood that comes from what we eat. Our cells use glucose for energy. A hormone called insulin helps glucose get into the cells. If a patient has diabetes, their body doesn't produce enough insulin, or the cells don't use it well.

As a result, glucose blood' levels increase due to not being pushed into the cells. Increased blood glucose levels stick to hemoglobin, a protein in the red blood cells. As the blood glucose levels increase, more hemoglobin will be coated with glucose.

The test can show the average glucose level for the past three months because glucose sticks to hemoglobin for as long as the red blood cells are alive(approximately three months). This makes the hemoglobin A1C test an important indicator of long-term glycemic control.

Which Patients is the Hemoglobin A1c (HbA1c)Test with ZRT Best Used For?

A practitioner may request a hemoglobin A1C test to screen for or diagnose type 2 diabetes or if they suspect pre-diabetes.

In prediabetes screening, the blood glucose levels are higher than average but not high enough to confirm a diagnosis of diabetes. In this situation, lifestyle changes, such as exercise and healthy eating, may help delay or prevent pre-diabetes from becoming type 2 diabetes.

In patients diagnosed with either diabetes or pre-diabetes, the test can help monitor the condition so practitioners can modify the treatment as necessary.

About the Test

This is a single-marker test measuring hemoglobin A1c (HbA1c). HbA1c is used to monitor long-term glucose control in individuals with diabetes mellitus.
