PTT vs PT. PTT is ‘partial thromboplastin time’, and PT is ‘prothrombin time.’ Both PTT and PT are tests used for measuring the time taken for the blood to clot. These two tests are mainly conducted for checking for bleeding problems or the chances of excessive bleeding during surgery.

PT and APTT: The PT, INR, and Activated Partial. Thromboplastin Time (APTT) tests are common coagula-. tion laboratory tests used to assess the clotting ability of. blood. The PT/INR test evaluates the extrinsic and com-. mon pathways of the coagulation cascade, while the APTT. test evaluates the intrinsic and common pathways. Using. both tests examines the integrated function of the coagula-. tion factors. INR: Differences in thromboplastin reagents have caused.

1. PTT is ‘partial thromboplastin time’ and PT is ‘prothrombin time.’. 2. The PT measures the extrinsic coagulation pathway by calculating the prothrombin ratio along with the international normalized ratio. 3. The PTT is a measurement of the intrinsic coagulation pathway and the common coagulation pathway.

In brief: Uniform standered. Pt is prothrombin time, inr is international normalized ratio, both measure cloting tendency in disease and in health. In pt each time you need contol which varies place to place and some what unpredictble. So inr solves the problem by uniform standred all over the world.

Prothrombin time test results can be presented in two ways. The average time range for blood to clot is about 10 to 14 seconds. A number higher than that range means it takes blood longer than usual to clot. A number lower than that range means blood clots more quickly than normal.

of seconds compared to the INR. A patient with an INR of 2.0 (remember the INRs will be equivalent) will. show a PT of 26.1 seconds using a sensitive ISI reagent (1.0) versus 16.0 seconds an insensitive ISI reagent.

In healthy people an INR of 1.1 or below is considered normal. An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking warfarin for disorders such as atrial fibrillation or a blood clot in the leg or lung. In certain situations, such as having a mechanical heart valve, you might need a slightly higher INR.

INR and APTT are two types of test conducted to measure the coagulation of blood in the patient. INR stands for “International Normalized Ratio”. It is also called “ProTime INR” and “INR PT”. APTT, on the other hand, stands for “Activated Partial Thromboplastin Time”. The international normalized ratio is derived form the prothrombin time (PT) and the prothrombin ratio (PR). These are used to measure the extrinsic pathway of coagulation.

The Relationship of the International Normalized Ratio (INR) to the Prothrombin Time (PT) By: William DePond MD, President and Chief Medical Officer MEDLAB. In 1983, it was determined that patients receiving long-term anticoagulant therapy may be subject to.

difference between protime and inr
PT is ProthrombinTime, INR is International Normalized Ratio.
