The Prothrombin Time (PT) test or clotting test is the test related to blood clotting time. There are various types of cells in the blood like RBC’s, WBC’s and platelets. These cells perform specific functions in the blood. Platelet blood cells are used for the clotting of blood whenever any cut occurs. After bleeding for some time bleeding stops due to the presence of platelets. There is a factor secreted by platelets called prothrombin which is used in clotting the blood. The time taken by platelets to make the clot is called clotting time and the test is called prothrombin time (PT) test. The price of Prothrombin Time (PT) test in Delhi is INR 100.
The prothrombin time or PT test is the time taken by plasma to make a clot which helps to stop the bleeding. The test is done by adding reagents to the blood sample in the laboratory to calculate the time. Reagents added to blood activate different clotting factors like:
| S. No. | Prothrombin Time (Seconds) | Interpretation |
| 1. | 11 – 14 seconds | Normal |
| 2. | 15 – 20 seconds | Mild prolongation |
| 3. | 21 – 30 seconds | Moderate prolongation |
| 4. | Above 30 seconds | Severe clotting abnormality |

| 2. | Liver disease | Reduced clotting factor production |
| 3. | Vitamin K deficiency | Impaired clotting factor synthesis |
