Diagnostic services also play a vital role in screening — identifying conditions before they cause symptoms.
The offices of Dawei Zheng, MD, ABFM, offer many on-site diagnostic services, including:
An EKG records the heart’s electrical activity to evaluate its function.
Spirometry tests your lung function by measuring how much air you can exhale.
When you have hearing tests, the results produce an image called an audiogram.
People with diabetes often develop conditions like glaucoma, cataracts, and diabetic retinopathy that can cause sight loss. Diabetic retinal exams identify these problems early on.
Glaucoma is a serious eye condition where fluid buildup in the eyeball leads to increased pressure that damages the optic nerve. Diaton tonometry measures intraocular pressure (IOP), a key indicator for glaucoma.
Testing urine can identify problems ranging from urinary tract infections (UTIs) and kidney disorders to raised blood sugar and hormonal issues. It’s also the easiest way to determine if you’re pregnant.
HbA1c is a test for diabetes that measures your average blood glucose levels over the previous three months.
Blood and other lab tests can also identify problems like sexually transmitted diseases (STDs), nutrient deficiencies, allergies, skin conditions, and bacterial, viral, or fungal infections.
Most diagnostic services are straightforward and noninvasive. An EKG involves having sticky pads on your chest and large arteries that transmit information to the machine. The EKG translates the electrical signals and produces a graph for your provider to examine.
Lab tests require samples, most commonly blood or urine, but sometimes skin or other cells, throat or nasal swabs, discharge fluids, stool, or sputum. Most people experience minimal discomfort during a blood draw, but if you don’t like needles, you can apply a numbing cream to your skin beforehand.
