METHOD FOR THROMBIN AND FIBRINOGEN ACTIVITY AND FUNCTIONALITY TEST Russian patent published in 2012 - IPC G01N33/86 C12Q1/56 

FIELD: medicine.

SUBSTANCE: method for thrombin activity test in an initially non-reacted mixture of thrombin and fibrinogen (versions) involving the stages: (a) reversible thrombin inhibition by adding an inhibitory solution having pH varying within the range of 8.5 to 11.5; (b) addition of the known amount of fibrinogen to the mixture (or the known amount of a chromogenic or fluorogenic thrombin substrate), (c) reversible thrombin activation by pH reduction to approximately 6.0 to less than 8.5, (d) enabling thrombin reacting with fibrinogen, (e) thrombin activity test initially found in the dry mixture. The method for fibrinogen functionality test in an initially non-reacted mixture of thrombin and fibrinogen (versions) involving the stages: (a) reversible thrombin inhibition by adding an inhibitory solution having pH varying within the range of 8.5 to 11.5; (b) addition of the known amount of thrombin to the mixture (or a thrombin-like enzyme), (c) reversible thrombin activation by pH reduction to approximately 6.0 to less than 8.5, (d) enabling thrombin reacting with fibrinogen, (e) fibrinogen functionality test initially found in the dry mixture.

EFFECT: group of inventions enables higher accuracy of thrombin and fibrinogen activity test.
