They also did a test to see how fast my blood clotted, by slicing my forearm with a thing kind of like a spring loaded lancet, but with 2 little blades that made shallow cuts (still have the 2 little scars from it) & then, timed it until my blood stopped coming out.
It's called a "bleeding time" test. That was a test I use to perform on some of my patients. Very useful test for pre-op.
