Laboratory Test for Bleeding Time
The laboratory test that measures bleeding time is:
- Bleeding time (BT) test, also known as the Simplate test 1
- This test is used to assess platelet function and diagnose bleeding disorders 2, 3
Description of the Test
- The bleeding time test involves making a standardized incision on the volar surface of the forearm and measuring the duration of blood flow 4
- The test can be performed using a disposable device, such as the Simplate-I 4
- The bleeding time is affected by various factors, including platelet count, diseases, drugs, and physiologic factors 2
Clinical Utility
- The bleeding time test is useful for assessing platelet function in patients with hemorrhagic disorders 3
- However, its utility in providing helpful clinical information in patients without a known bleeding diathesis is minimal 3
- The test has been proposed for use as a diagnostic test for platelet-related bleeding disorders, a measure of efficacy in various forms of therapy, and as a prognosticator of abnormal bleeding 2, 5
