What is a Prothrombin Time (PT INR/ APTT)?
This coagulation profile measures how long your blood takes to clot through two pathways: Prothrombin Time (PT, reported with the standardised INR) and Activated Partial Thromboplastin Time (APTT). Together they screen for bleeding and clotting disorders and are essential for safely monitoring blood-thinning medicines such as warfarin (acitrom).
What it measures
PT (Prothrombin Time)
Time to clot via the extrinsic pathway; the basis of the INR.
INR
A standardised version of PT so results are comparable between labs, the number used to dose warfarin.
APTT
Time to clot via the intrinsic pathway; screens for other clotting-factor or heparin effects.
Why take this test?
It is advised to monitor blood-thinner dosing (the INR target), to investigate unexplained bruising or bleeding, before surgery, and in liver disease, since the liver makes most clotting factors. The INR keeps warfarin in a safe, effective range.
- On warfarin / acitrom, for regular INR monitoring
- Unexplained bruising, nosebleeds, or bleeding
- Before surgery or an invasive procedure
- Liver disease assessment
Normal reference ranges
| Parameter | Healthy reference range |
|---|---|
| PT | 11 - 13.5 seconds |
| INR (not on blood thinners) | 0.8 - 1.1 |
| INR (target on warfarin) | Usually 2.0 - 3.0, set by your doctor |
| APTT | 25 - 35 seconds |
Ranges are indicative for adults. Your report carries the lab-specific reference range and is reviewed by a LabONE pathologist; always interpret results with your doctor.
