Abstract
Test articles comprise a solid phase membrane having dry thromboplastin immobilized thereon or within. The thromboplastin is substantially free from substances which might cause aberrant functioning intermediate transition states as the thromboplastin is rehydrated with liquid sample. Coagulation neutral agents which facilitate rehydration of the dry thromboplastin are also provided on the solid phase membrane.
