I've had different tests done by Lifeline Screening. None were invasive at all. Many of the tests, including the carotid artery test, are ultrasounds.
In an ultrasound a technician applies a small amount of gel to the body part in question, after which he rubs that body part with a small hand-held device that emits sound waves and records the echo as the waves bounce off tissues, organs and blood cells.
A computer translates the echoed sound waves into a live-action image on a monitor. The carotid artery test uses an ultrasound which shows blood flowing through the arteries. The rate of blood flow is translated into a graph. A photo of the carotid artery test is attached below.
It's all very organized and the testing, even when I've had 7-8 tests scheduled, has never taken longer than 30 minutes. The tests I've had recently are:
Carotid Artery Disease
Atrial Fibrillation
Abdominal Aortic Aneurysm
Peripheral Arterial Disease
Osteoporosis
High Cholesterol Screening/Complete Lipid Panel
Body Mass Index
For the atrial fibrillation test, a technician attaches EKG electrodes to your arms and wrists and takes readings.
The peripheral arterial disease test compares the blood pressure in your legs to that in your arms. I removed my socks and shoes and pressure cuffs were placed around my upper arms and ankles. A small ultrasound device then measured the systolic blood pressure in my limbs.
I received a detailed 20-page test results within 2-3 weeks of taking the last set of tests.
