Episode notes
Prolonged Clotting Time Significance
- Prolonged clotting times in a lab test indicate a potential bleeding issue.
- This can be caused by factor deficiencies, inhibition, or technical issues.
Platelets and Clotting Times
- Platelet deficiencies do not prolong clotting times in standard lab tests like PT or APTT.
- These tests remove platelets, so platelet function isn't assessed.
Anticoagulant vs. Antiplatelet
- Anticoagulants and antiplatelet agents are distinct drug categories.
- Differentiate between them when consulting hematology to avoid confusion.
