What is the advantage of using the INR value?
INR is the international unit, recommended worldwide, for thromboplastin time (PT) determination. The WHO recommended the use of the INR instead of the Quick value as the unit for the measurement of coagulation right back in the early 1980s. Reasons for using INR: • INR is comparable, i.e. coagulation measuring values can be compared despite different thromboplastins. • INR allows a standardisation of coagulation intensity for certain indication groups, independent of the thromboplastin and instrument used. • INR allows better patient therapy monitoring. The INR value is in inverse proportion to the Quick value.
