Study type
Interventional
Description of intervention(s) / exposure
The aim of this study is to measure prothrombin time (PT) expressed in International Normalised Ratio (INR) units in persons receiving warfarin treatment on an experimental device, commercially available point of care device and a standard laboratory method.
This will involve taking a venous sample from both persons receiving warfarin treatment (experimental group) and persons not receiving warfarin treatment (control group). All persons are currently undergoing testing at a clinic. Samples collected are tested by laboratory staff on the experimental point of care device, commercially available device and standard laboratory reference instrument.
It is expected that the persons participation does not exceed the time it takes to complete informed consent form and have a venous sample collected.
