Thromboplastin reagent and method for manufacturing the same

摘要

This invention provides a novel thromboplastin reagent having high measurement sensitivity. Thus, an effective amount of amino acid or derivative thereof having such a function that an ISI (international sensitivity index) of a composition of thromboplastin showing an ISI of more than 1.0 is made nearer 1.0 is added whereby a thromboplastin having a high measurement sensitivity is provided. To be more specific, sodium glutamate is added in an effective amount.
