23
Q

VWF disease which one prolonged ?

A

BT CT APTT

24
Q

VWd confirmatory test ?

A

factor VIII ASSAY = normal/dec
VWF assat = dec/nai

25
PC normal but BT prolonged why ?
platelet adhesion defect resulting from VWF deficiency
26
WHich parhway defect in H >
intricnsic
26
why factor-VIII is dec in VWF ?
VWF prevents the lysis of factor-VIII
27
WHY APTT is prolonged in Haemophilia >
APTT is prolobged due to inc in 1 2 5 8 9 10 factor factor 8 specific for APTT
