I am doing some benchmarking.

What are your refence ranges for the PFA?

We are a three hospital system and our aggregate reference ranges are:

EPI: 74-178 sec

ADP: 55-103 sec

Thanks in advance for your reply.

Ours are very similar to yours.

EPI: 80-184

ADP 56-102

Ours also simular: EPI 77-170, ADP 57-109

Just found this thread, maybe you've moved on, but for what it's worth our ranges are

EPI 81-181, ADP 58-107. These ranges are for 2.7ml plastic tubes, with tests run on the second tube drawn, not a single tube draw.

we use

Collagen/Epinephrine 95-185

Collagen/ADP 65-120
