Thank you guys for your input. Just one more question. If arterial duplex is
more precise and an ABI is included, why do labs do LPVR? This seems like an
extra step and another extra cost to patient. Our lab is set up to do LPVR.
When a Dr. orders an arterial we do ABI's. If it is normal, we don't do anything
else. But if it is abnormal, we do a full PVR. We do ABI's whether the order
saids duplex or LPVR because our protocol is to do LPVR. We have one
vascular surgeon who demands we do both even thought our arterial protocol
is for LPVR. What is the protocol for most vascular labs?
