iLine - Model microINR Chip -Disposable Plastic Test Strip
The microINR Chip is a disposable plastic test strip, that encloses two microcapillary channels, of extremely simple construction and fully passive (i.e. no built-in sensors, nor electrodes, nor external pumping).

The INR determination is achieved through sample flow monitoring along the microcapillary channels of the Chip, following the activation of the coagulation cascade. The current IVD test mimics the conditions of “in vivo” hemostasis, also referred as “ex vivo”
The blood sample introduction is performed through the entry channel, where the sample flows by capillary action.
The measured prothrombin time is converted into INR using lot-specific calibration parameters microprinted on the Chip surface (Datamatrix)
