used to monitor the heparin therapy, but now it is replaced by the APTT.

Answer 19

Test tube/Lee-white method

Question 20

Devices that measure the clotting
mechanisms of hemostasis

Answer 20

Coagulation Analyzer

Question 21

Principle that uses blood
viscosity changes to determine clotting
time.

Answer 21

Mechanical impedance

Question 22

Principle that monitor changes
in the specimen’s optical density to detect the beginning of clot formation.

Principle When a clot
forms, it entangles the magnet, breaking the electromagnetic coupling and allowing the magnet to rotate with the tube,

Answer 23

Electromagnetic principle
