Bone Density Screening

A bone density test uses X-rays to determine whether you have osteoporosis or are at risk of developing osteoporosis. It measures how much calcium is in your bones; the more calcium you have, the denser and stronger your bones are.

Continuous Glucose Monitoring

Continuous glucose monitoring is a device that records blood sugar levels 24 hours a day for three consecutive days. It can help identify fluctuations and trends that would otherwise go undetected with standard HbA1c tests and intermittent finger stick measurements. Your doctor will review the data gathered by the device and make any necessary adjustments in your diabetes management plan.

Peripheral Artery Ultrasound

A peripheral arterial ultrasound test can screen for stroke, peripheral artery disease of the legs, and aortic aneurysm, a common and potentially fatal disease.

Peripheral Arterial Disease (PAD).

Peripheral Venous Ultrasound

A peripheral venous ultrasound is a simple imaging assessment that creates images of veins to identify the direction of blood flow and blockages. Venous ultrasound is useful for identifying clots (deep vein thrombosis), varicose veins and chronic venous insufficiency.

Peripheral Arterial Disease (PAD).

Abdominal Ultrasound

An abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys, as well as the blood vessels that lead to some of these organs. It is used to diagnose the cause of abdominal pain or kidney infections, or to diagnose a hernia, kidney stones or gallstones.

Renal Ultrasound

A renal ultrasound is an imaging procedure used to study the renal system, which includes the kidneys, bladder, and ureters (the tubes that connect the kidneys to the bladder). It is used to look for changes in the bladder wall, kidneys, or ureters; kidney stones or stones in the urinary tract; and blood flow to the kidneys.
