What is this test?
Bleeding time records how long a standardized small skin puncture takes to stop bleeding. It is an older, method-dependent assessment of primary haemostasis and platelet-related bleeding, not a complete evaluation of clotting.
Why might it be ordered?
- When a clinician specifically requests this method to investigate bleeding.
- As one part of a wider assessment that may include blood counts and other coagulation tests.
What sample is needed?
This is usually a procedure on the skin rather than a blood-tube measurement. Ask the laboratory how it performs the test.
How should you prepare?
Tell the clinician about aspirin, anti-inflammatory medicines, anticoagulants and supplements that affect bleeding. Do not stop any of them without instructions.
How should you understand the result?
A prolonged time is nonspecific, and a normal time does not exclude a bleeding disorder. Technique, skin and medicines can influence the measurement.
