Overview

The PT INR APTT test is a blood test used to measure how long it takes for the blood to clot. The test is performed by collecting a blood sample from a vein in the arm and then placing it in a tube with a substance that triggers clotting. The time it takes for the blood to clot is measured and compared to a standard range to determine if there is a bleeding or clotting disorder. This test is commonly used to monitor patients taking blood thinning medications.

Who should do this test?

Patients who are on anticoagulant therapy, such as warfarin, heparin, or dabigatran, to monitor their blood clotting levels and adjust their medication dosages accordingly.

Individuals with bleeding disorders, such as hemophilia, who require regular monitoring of their clotting factors to prevent excessive bleeding or to assess the effectiveness of their treatment.

Patients who are undergoing surgery or other invasive procedures, where the risk of bleeding is increased, to assess their clotting ability and ensure safe surgical outcomes.

What to do if the test is abnormal?

Consult with a healthcare provider: If the results of PT, INR, or APTT tests are abnormal, the patient should consult with their healthcare provider for further evaluation and treatment. The healthcare provider can review the patients medical history, medications, and other factors that may be contributing to the abnormal results.

Follow the healthcare providers recommendations: Based on the evaluation of the patients results and medical history, the healthcare provider may recommend additional tests, medications, or other interventions to treat the underlying condition. It is important that the patient follows the providers recommendations to manage the condition and prevent complications.

Monitor regularly: Depending on the underlying condition and treatment plan, the patient may need to have their PT, INR, or APTT levels monitored regularly. This may involve regular blood tests or other types of monitoring to ensure that the treatment plan is effective and that the patients condition is well-managed.

The normal range for prothrombin time is between 12.51 - 15.07 seconds. The range may vary depending on the population and age group.

The INR is a method of standardizing the Prothrombin time across different labs. . Since different labs use different machines and reagents to calculate the Prothrombin time, the INR allows these values to be normalized so that they can be compared.. It also depends on the specific reagent of chemical used for the test. The INR is derived from the mean Prothrombin Time value of a cohort of patient samples, using a factor called the ISI (provided by the equipment manufacturer)

The normal range of INR is usually between 0.8 - 1.3. On patients who are being treated with warfarin, the target range is between 2 and 3.

The normal range for APTT Is usually between 26.22 - 38.62 seconds.. Target values for patients on heparin therapy are usually 1.5 - 2 times higher than the base normal range.
