Prothrombin Time (PT) with INR & PTT for Selden Residents
This page explains the prothrombin time (pt) with inr & ptt in Selden, NY, what it measures, and how to order it. This test measures how long it takes your blood to clot and helps assess your risk of bleeding or clotting.
What this test is
Prothrombin Time (PT) with International Normalized Ratio (INR) and Partial Thromboplastin Time (PTT) are blood tests that evaluate the body's ability to form clots. They assess different parts of the coagulation cascade, a series of protein interactions that lead to blood clotting.
What it measures
- Prothrombin Time (PT) — reflects the time it takes for blood to clot
- International Normalized Ratio (INR) — standardizes PT results for comparison across different labs
- Partial Thromboplastin Time (PTT) — measures how long it takes for blood to clot using a different pathway
What the test involves
A healthcare professional will collect a blood sample by inserting a needle into a vein, typically in your arm. The collected blood is then sent to a laboratory for analysis.
Why it is often ordered
Clinicians often order this test to monitor individuals taking anticoagulant medications, such as warfarin. It may also be used to investigate unexplained bleeding or clotting disorders.
Preparation
Follow any specific instructions provided by the laboratory where you will have your blood drawn. Some medications may need to be temporarily stopped before the test.
How results are reported
Results are typically reported within a few business days. Your results will include reference ranges, which are the expected values for healthy individuals, but these ranges can vary between laboratories.

FAQ
Frequently asked questions
What is the difference between PT and PTT?
PT and PTT are both clotting tests but measure different parts of the blood clotting process. PT primarily assesses the extrinsic pathway, while PTT assesses the intrinsic pathway of coagulation.
What does a high PT or PTT result mean?
Elevated PT or PTT results may indicate that your blood is taking longer than usual to clot, which could increase your risk of bleeding. This can be due to various factors, including medications or underlying medical conditions.
What does a low PT or PTT result mean?
Low PT or PTT results are less common and typically suggest that your blood clots faster than normal. This could potentially increase your risk of developing blood clots.
How long does it take to get results?
The typical turnaround time for this test is 1-3 business days after the sample is collected. However, the exact time can depend on the laboratory processing your sample.
