What coag Factors are contact factors? - CORRECT ANSWERS✅✅XII, XI, Fletcher and
Fitzgerald
What Coag Factors are Labile? - CORRECT ANSWERS✅✅V, VIII
What Coag Factor is a comon path factor, Normal PT, Increase PTT and is Hemophilia B
(Christmas Dz)? - CORRECT ANSWERS✅✅Factoer IX deficiency
What coag factor has a normal PT, Normal PTT, Measure with urea solubility, Treat with
cryoprecipitate? - CORRECT ANSWERS✅✅Factor XIII Deficiency
What coag factor has a Normal PT, Increase PTT, Causes thrombosis not bleeding? -
CORRECT ANSWERS✅✅Factor XII deficiency
What coag factor has increase PT and PTT, Measured by Thrombin Time, Treat with
cryoprecipitate? - CORRECT ANSWERS✅✅Factor I deficiency
What coag Factor has increase PT and normal PTT? - CORRECT ANSWERS✅✅Factor VII
deficiency
What coag factor has increase PT and PTT? - CORRECT ANSWERS✅✅Factor X
deficiency
, Why does liver dz cause bleeding? - CORRECT ANSWERS✅✅Most plasma coag factors
are produced in the liver so if the liver is dzed, production is reduced. If the concentration of
factors is reduced, the coag test will be prolonged.
What factor is normal or elevated in liver dz? - CORRECT ANSWERS✅✅Factor VIII is
partly produced by vessel endothelial cells so it is normal or increased in liver dz.
What is the purpose of the trypsin inhibitor in FSP or FDP slide agglutination test? -
CORRECT ANSWERS✅✅Trypsin is an antifibrinolytic agent so it prevents invitro
fibrinolysis, allowing the test to detect only the fibrinolysis that occurred in the pt prior to the
blood collection.
What is the diagnosis if a patient has a + FSP and negative D-Dimer? - CORRECT
ANSWERS✅✅Primary or pathologic fibrinogenolysis
What is the diagnosis if a patient has a + FSP and + D-Dimer? - CORRECT
ANSWERS✅✅DIC or thrombosis
List the factors in the extrinsic system? - CORRECT ANSWERS✅✅III and VII
List the factors in the intrinsic system? - CORRECT ANSWERS✅✅XII, XI, IX, VIII
What is the therapeutic range for INR? - CORRECT ANSWERS✅✅2.0-3.0 for most
patients on coumadin
What are the reagents used in the PT? - CORRECT ANSWERS✅✅Rabbit thromboplastin
Calcium in the thromboplastin
What are the reagents used in the PTT - CORRECT ANSWERS✅✅Activated partial
thromboplastin (Actin)
Calcium Chloride
