HEMA 2 RATIO

It measures the time required to generate thrombin and fibrin polymers via intrinsic pathway:

• APTT

• PT

• TT

• NOTA

The following are negatively charged particulate activator used in APTT except

• Thrombin

• -

An increased in APTT will affect the following coagulation factor, Except

• Factor V

• Factor II

• Factor VII

• Factor VIII

Determines the rate of thrombin-induced cleavage of fibrinogen to fibrin monomers and subsequent polymerization of hydrogen bonded polymers:

• APTT

• PT

• TT

• NOTA

It is also known as the plasma thromboplastin antecedent

• Factor IX

• Factor XI

• Factor XII

• Factor X

It is also known as the plasma thromboplastin component

• FIX

• FX

• FXI

• FXII

The following coagulation factor are consumed during the process of coagulation, except

• FXII

• FVII

• FII

• FXIII

Which of the following coagulation factor is inhibited by warfarin?

• FII

• FX

• FIX

• FVII

The specimen if a patient with prolong APTT was subjected to a mixing study shows correction of APTT after immediate mixing but no correction after a 2-hour incubation was possibly indicated by:

• Factor Deficiency

• Factor VIII Inhibitor

• Leiden Inhibitor

• Factor V Inhibitor

This procedure is used to monitor oral anticoagulant therapy, a screening test in diagnosis of coagulation deficiencies and a component of liver profile assessment

• APTT

• PT

• TT
