PLASMASCANN®, 10 x 2 mL

PRINCIPLE

Prothrombin time or Quick time is the time, in seconds, necessary for plasma to clot at 37ºC, once an external coagulation factor (thromboplastin) and Ca2+ has been added. Long coagulation times with regard to those obtained for healthy people indicate a defi ciency in some of the components of the coagulation system.

DIAGNOSTIC USE

Plasmascann® is a calcium thromboplastin, freeze-dried, that allows the determination of variations in those coagulation factors (especially factors VII and X) that have been depressed during the treatment with coumarinic derivatives, in vitamin K defi ciency, hepatopathy or due to a hereditary abnormally in the coagulation system. The reagent has been obtained from a rabbit brain extract, and it is standardized from lot to lot according to the technique of Hills-Ingram. Single test result could not be used to make a clinical diagnosis. It should integrate clinical and laboratory data.
