It measures the duration of bleeding after a measured skin incision.
Bleeding time
The most accurate bleeding time method is:
Modified template/simplate method
Bleeding time is NOT recommended when platelet count is less than:
75,000/µL
[3] Common puncture sites for bleeding time:
- Finger
- Earlobe
- Forearm
During bleeding time determination, filter paper is blotted every:
30 seconds
If bleeding continues beyond 15 minutes, the test should be:
Discontinued and reported as >15 minutes
Reference range for Duke bleeding time.
2 - 8 minutes
Patient preparation includes checking history for use of:
Drugs that prolong bleeding time
What drug may prolong bleeding time for up to two weeks?
Aspirin
In Ivy’s method, cuff pressure is maintained at?
40 mmHg
The time between CUFF INFLATION and INCISION in Ivy’s method should be?
30 - 60 seconds
In Ivy’s method, how many punctures are made?
3
The puncture depth in Ivy’s method is?
3 mm
Touching the filter paper directly to the incision should be avoided to prevent:
Disturbance of platelet plug formation.
Normal Ivy bleeding time reference range.
3 - 6 minutes
Borderline bleeding time is
6 - 11 minutes
LOW SKIN temperature affects bleeding time by causing.
Capillaryn constriction
Bleeding time is prolonged in:
Thrombocytopenia
Bleeding time is normal in:
Hemophilia
Bleeding time should NOT be performed in known HEMOPHILIACS because of:
Delayed oozing risk
Thrombocytopenic purpura prolongs bleeding time due to:
Defective platelet plug
Which disease is associated with abnormal platelet function?
Bernard - Soulier disease
Test for in vivo platelet adhesion.
Bleeding time
Used to assess platelet function and number.
