Understanding Coagulation Profile (PT/INR & aPTT) in Chennai
What is Coagulation Profile (PT/INR & aPTT) in Chennai?
A Coagulation Profile (PT/INR & aPTT) is a blood test that evaluates the clotting ability of the blood. It typically includes tests such as prothrombin time international normalized ratio (PT/INR) and activated Partial Thromboplastin Time (aPTT). These tests assess different aspects of the blood’s ability to clot properly through various pathways. Results from a Coagulation Profile (PT/INR & aPTT) help diagnose and monitor conditions such as bleeding disorders, clotting disorders, liver diseases, and the effectiveness of anticoagulant therapy. This test is available at an affordable price in Chennai with Tata 1mg Labs.
Your doctor may suggest Coagulation Profile (PT/INR & aPTT) if you have a history of unexplained bleeding or bruising, or before a surgical procedure to evaluate the risk of excessive bleeding. Overnight fasting (8-12 hours) is preferred for this profile. However, drinking water is acceptable. A duly filled coagulation requisition form is mandatory for sample collection. Also, inform the doctor if you are taking medications such as blood thinners, as they may interfere with test results, and your doctor may adjust your dosage or ask you to stop them temporarily before the test.
What does Coagulation Profile (PT/INR & aPTT) measure?
Contains 2 testsA Coagulation Profile (PT/INR & aPTT) includes blood tests that provide information about the blood's clotting ability. This profile measures prothrombin time international normalized ratio (PT/INR) and activated partial thromboplastin time (aPTT).
The Prothrombin Time (PT) and aPTT tests measure how long the blood takes to clot. Precisely, they assess the factors in the blood that help initiate the clotting process. The INR is a standardized interpretation of the PT results. It is calculated to ensure consistency in interpreting PT values across different laboratories and testing methods. The INR is essential when monitoring patients on anticoagulant medications like warfarin. The INR helps adjust medication dosages to maintain blood clotting within a therapeutic range. The aPTT test is significant when monitoring patients on anticoagulant medications, such as heparin.
PT INR (Prothrombin Time)
The PT INR (Prothrombin Time) test measures the Prothrombin Time (PT) and reports it as the International Normalized Ratio (INR). The PT measures how long it takes for blood to clot. Specifically, it assesses the factors in the blood that help initiate the clotting process. The INR is a standardized interpretation of the PT results. It is calculated to ensure consistency in interpreting PT values across different laboratories and testing methods. It is particularly important when monitoring patients on anticoagulant medications, such as warfarin. The INR helps adjust medication dosages to maintain blood clotting within a therapeutic range.

Activated Partial Thromboplastin Time
An Activated Partial Thromboplastin Time test measures the time taken by the blood to form a clot. In other words, it is a screening test that helps evaluate a person’s ability to form blood clots. The test analyzes the amount and the function of specific proteins in the blood called coagulation or clotting factors, which are an essential part of blood clot formation.
Blood clotting or coagulation occurs through a series of cascade reactions due to the activation of clotting factors. There are a total of thirteen clotting factors within our bodies that aid in clot formation, and for healthy clot formation, all clotting factors need to be in the right balance. Any imbalance of these factors can lead to a blood clotting disorder.
