TEST FOR FIBRINOLYSIS Flashcards
What are the 2 types of fibrinolysis?
Primary fibrinolysis
Secondary fibrinolysis
This type of fibrinolysis occurs naturally
Primary fibrinolysis
In the primary fibrinolysis, after coagulation cascade, it will naturally _________?
Breakdown clot
This type of fibrinolysis is due to an external cause.
Secondary fibrinolysis
Give an example of secondary fibrinolysis
Medication, Trauma
What will secondary fibrinolysis cause?
Excessive bleeding
Enumerate the test for fibrinolysis
Euglobulin clot lysis time
Ethanol gelation time
Protamin sulfate test
D-dimer test
What do the plasma euglobulin fraction contain?
Plasminogen
Activators of plasminogen and fibrinogen
What is the principle of ECLT?
The plasma euglobulin is precipitated using 1% acetic acid
Under ECLT, the precipitates are redissolved and clotted with _______?
Thrombin
At what temperature is complete lysis measured in ECLT?
37°C
What is the normal clot lysis time under ECLT?
2 - 4 hours
What value under ECLT, is indicative of abnormal fibrinolytic activity?
<2 hours
What does <2 hours indicate in ECLT?
Abnormal fibrinolytic activity
Enumerate the causes of INCREASE FIBRINOLYSIS
Circulatory collapse
Adrenaline injection
Sudden death
Pulmonary surgery
Pyrogen reaction
Obstetric complication
What value indicates “increase fibrinolysis”?
> 4 hours
Who made the ethanol gelation test?
Breen and Tullis
Ethanol gelation test and Protamine sulfate test are both used to detect what?
Presence of fibrin monomer in the plasma
EGT and PST, are utilized as an aid in the diagnosis of?
Disseminated Intravascular Coagulation
What reagent is added to the blood sample for a gel formation to be made under EGT and PST?
50% ethanol
What is the positive result of the Ethanol Gelation Test and Protamine Sulfate Test?
Clotting or clot formation
What is the negative result of EGT & PST?
No gel formation
This is the most specific test for fibrin degradation products (FDP)
D-Dimer test
