Coumadin (warfarin)
Subjects are required to be currently receiving coumadin (warfarin) treatment.

Primary Outcome Measures :
  1. PT/INR values from the experimental device will be statistically correlated to results obtained from a commercially available device [ Time Frame: Fives days to collect data and up to two weeks to generate correlation graph ]
    To determine the correlation of PT/INR values between an experimental and commercial device.
