8 sie 2023 · The measurement of bleeding time is mostly of historical value in the screening of qualitative platelet abnormalities. It was used to screen for bleeding disorders and quantify platelet function in patients taking aspirin or non-steroidal anti-inflammatory medications.
25 wrz 2020 · Interpretation. General interpretations of bleeding time are as follows: 1-9 minutes: Normal. 9-15 minutes: Platelet dysfunction. More than 15 minutes: Critical; test must be discontinued...

Useful in detecting disorders of platelet function. Prolonged bleeding time or increased levels may indicate: Bone marrow failure; Bernard-Soulier syndrome; Capillary ...

The normal time is usually reported as less than 30 to 35 seconds depending on the technique used. In fact, there is a normal range of about 10 seconds (e.g., 25 to 35), and decreased values ("short") may also be abnormal.
8 cze 2024 · Normal PT values range from 9 to 13 seconds. Higher PT values indicate a prolonged clotting time, suggesting potential issues with clotting factors such as fibrinogen, factor V, VII, X, and prothrombin. Abnormal PT values may indicate liver disease, vitamin K deficiency, or the presence of anticoagulants. Partial Thromboplastin Time
Interpretation of the results according to a well-established reference range is important. At the moment, indications of bleeding time are very limited due to its poor sensitivity and reproducibility. More sensitive and specific assays have been developed for the diagnosis of specific conditions.
