Sending a Coag-Sense across country probably isn't the most practical suggestion. A few thoughts -- although my experience with the InRatio monitor got results that were HIGHER than the labs and usually higher than the CoaguChek XS (and almost always higher than the Coag-Sense), you may be able to find someone in the Virginia area who has an InRatio and may let you try a test or two using the inRatio. Whatever it is that is causing the CoaguChek XS to give erroneous results may not cause the InRatio to do the same.
I have a few (don't ask) ProTime and ProTime 3 meters. As I've said before, these seem to be quite accurate but are a bit of a pain to use because they require more blood than the other meters require. They seem to need their rechargeable batteries replaced, but will work fine when plugged in to AC. I'm not sure when my strips expire, but if they're still current, I may be able to send you meter and a few strips as a loan. PM me and we can discuss this further.
The ProTime meters use a mechanical method to determine clotting, so they're probably insensitive to the hematocrit issues that may cause other POCs (except for the Coag-Sense) to report incorrect values.
