What is the indication of a positive result in this test?
A blood spot is visible on the filter paper
Why is it important to express the result in minutes and seconds?
To make the result more precise
Study Notes
Duke Bleeding Time Test
- The Duke bleeding time test is a simple and reliable test despite the fact that the depth of the wound cannot be controlled.
Materials and Instruments
- Materials needed: alcohol, lancets, stopwatch, and filter paper.
Procedure
- Start the stopwatch and note the time.
- Absorb/remove blood drops every 30 seconds by touching the puncture site with the filter paper along its edges without pressing or squeezing the wound.
- In the first two minutes, absorption should be repeated every 30 seconds.
- After two minutes, absorb every 15 seconds.
- Note the time when bleeding stops, i.e., when there is no trace of blood spot on the filter paper.
- Express the result in minutes and seconds.
Clinical Significance
- The test can detect shorter bleeding times in certain conditions, such as hemophilia (inherited blood clotting disorder) and thrombocytosis (excessive production of platelets in the bone marrow).
This quiz is a simple and reliable test on wound care, despite the fact that wound depth cannot be controlled. It requires knowledge of materials and instruments such as alcohol, lancets, and filter paper.
