NICE has assessed 2 point-of care coagulometers to help the NHS decide whether to use these products. They are called CoaguChek XS and InRatio2 PT/INR.
Coagulometers monitor blood clotting in people taking long-term anti-blood clotting drugs (such as warfarin) to reduce their risk of blood clots. These tests allow people taking anti-blood clotting drugs to monitor blood clotting themselves. They can then change their dose in agreement with their health professional.
Both coagulometers are recommended for use by people taking long-term anti-blood clotting therapy who have atrial fibrillation or heart valve disease, if they prefer and are able to effectively use this type of monitoring.
People (and their carers) who will be using 1 of these devices should be given training, and their doctor should regularly assess self-monitoring.
October 2016: NICE is aware that the INRatio2 PT/INR monitor (Alere Ltd) has been withdrawn from the market and is not currently available to the NHS.
