ultrasound is another way of doing it. I have no idea about the path through your finger. They know better than you and I.
The test they use on me requires a tiny, tiny, tiny pin insertion at various parts of my leg that barely pierces the epidermis. It's funny. . . the this site won't let me use the more descriptive word, because it represents something else. . . so I'll try this. . . a pin p*ick. Just insert an r where the asterisk is.
I'll call my vascular surgeon's office Tuesday and find out the term for the procedure they use on me.
