What is Partial Thromboplastin Time (PTT)?
Partial Thromboplastin Time (PTT), also known as Activated Partial Thromboplastin Time (aPTT), is a blood test that measures how long it takes for your blood to form a clot. This test specifically evaluates the intrinsic and common pathways of blood coagulation, assessing clotting factors VIII, IX, XI, and XII[5][6].
The test is essential for diagnosing bleeding disorders like hemophilia, monitoring heparin therapy, and assessing overall coagulation function. Our AI-powered report interpreter online analyzes your PTT results alongside other clinical factors to provide comprehensive insights into your clotting health[2][7].
Why PTT Testing Is Essential
PTT testing evaluates multiple clotting factors simultaneously, making it invaluable for detecting various bleeding disorders and monitoring anticoagulant therapy effectiveness[3][4].
- Bleeding disorder detection: Identifies conditions like hemophilia A and B, von Willebrand disease
- Heparin monitoring: Ensures safe and effective anticoagulant therapy dosing
- Preoperative screening: Assesses bleeding risk before surgical procedures
- Liver function assessment: Evaluates the liver's ability to produce clotting factors[7]
How the PTT Test Process Works
The PTT test involves adding specific reagents to your blood sample to activate the clotting process, then measuring the time required for clot formation[4][6].
Sample Collection: Blood drawn into tube with anticoagulant
Plasma Separation: Blood spun down to isolate plasma
Reagent Addition: PTT reagent added to activate clotting
Time Measurement: Clot formation time recorded in seconds
