I attended a mobile Life-Line screening yesterday near Charlotte and was quite satisfied with the staff and the procedures. The negative comment from Deb G. gave me pause, so I looked up information concerning medical equipement used to determine aterial flow. Here is what I found." There are several blood flow tests exist, and most use ultrasound technology. A probe is placed over the suspect artery -- especially arteries in the neck (carotid) or at the base of the skull (vertebral) -- and the amount of blood flow through a blood vessel is determined. " That procedure was used by the Life-Line staff--- if a problem was detected, a more extensive exam by your physician would be suggested by the staff-but for screening purposes, I think it more than adequately delivered as promised. I hate to think someone would defer getting tested by the negative comment. On-line sign-up and payment method was easy. The price was reasonable, and I was eligible for my free medicare annual wellness checkup, too. read more
