Community Screenings Overview
Hemoglobin A1c (also known as HbA1c)
What is the HbA1c screening for?
This test is used to diagnose prediabetes or diabetes. This is best combined with a fasting plasma glucose test, which is performed in physician’s office or clinic. HbA1c measures a person’s average blood sugar concentrations in the preceding two to three months.
Diabetic patients with very high blood concentrations of glucose have from 2 to 3 times more HbA1c than normal individuals.
Hemoglobin A1c measurement recommendations:
The American Diabetes Association recommends measurement of HbA1c on a average bases as follows:
- 3-4 times per year for type 1 and poorly controlled type 2 diabetic patients
- 2 times per year for well-controlled type 2 diabetic patients
Results indicating prediabetes are:
- An A1C of 5.7% – 6.4% • Fasting blood glucose of 100 – 125 mg/dl
- An OGTT 2 hour blood glucose of 140 mg/dl – 199 mg/dl

Urine Micro albumin Test
What is the Urine Microalbumin Test?
A urine micro albumin test is a test to detect very small levels of a blood protein (albumin) in your urine. A micro albumin test is used to detect early signs of kidney damage in people who are at risk of developing kidney disease.
If you have been diagnosed with Type II Diabetes, your physician will likely recommend this test being performed once a year.

Dilated Retinal Exam (DRE)
What is the Dilated Retinal Exam (DRE)?
A comprehensive eye examination will include a Dilated Retinal Exam to show signs of diabetic retinopathy. Dilation allows the eye care professional to view the inside of the eye.
In a person with diabetic retinopathy, the most common diabetic eye disease and a leading cause of blindness in the United States, the exam may show swelling or leaking of blood vessels in the retina, the light-sensitive layers of tissue at the back of the eye. The eye care professional may also see abnormal growth of blood vessels in the retina associated with diabetic retinopathy.
If you have diabetic retinopathy, at first you may notice no changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes.
The National Eye Institute recommends all people with diabetes, both type 1 and type 2, should get a comprehensive dilated eye exam at least once a year. Between 40 to 45 percent of Americans diagnosed with diabetes have some stage of diabetic retinopathy. If you have diabetic retinopathy, your eye care professional can recommend treatment to help prevent its progression.
