Looking over shoulder of lab technician for carotid ultrasound, unofficially read as normal. Precautionary diagnostic in assessing risk associated with high blood pressure, since my family practice doctor wants to prescribe medication, and my Traditional Chinese Medicine doctor assesses me as normal. Ultrasound is non-invasive, seemly more common in Asia, as the technician says that those patients arrive with previous histories in hand.
