As part of an investigation into a possible bleeding disorder or blood clot (thrombotic episode), to help investigate recurrent miscarriages or diagnose antiphospholipid syndrome (APS), it is needed to monitor unfractionated (standard) heparin anticoagulant therapy, as indicated as a part of an evaluation before surgery or other invasive procedure.
It is recommended: If a person experiences symptoms like frequent bleeding episodes, such as nose bleeding, easy bruising, bleeding from gums, blood in stools, abnormal periods in women, painful and swollen joints, etc. If a person is suffering from diseases or disorders associated with the blood, like vitamin K deficiency, leukaemia (cancer affecting the blood and bone marrow), haemophilia, clotting factor deficiency, etc., then it is important to consider the following: This test may also be advised by the doctor if the person is undergoing anticoagulant therapy.
The Activated Partial Thromboplastin Time (aPTT) test is used to measure: The Activated Partial Thromboplastin Time (aPTT) test measures the time taken by the blood to form a clot after the addition of substances (reagents) that activate the clot formation. The Activated Partial Thromboplastin Time (aPTT) test measures the time taken by the blood to form a clot after the addition of substances (calcium and phospholipid emulsion) that activate clotting. The aPTT test results are compared to an impact sample of normal blood. The aPTT test is usually performed along with the prothrombin time (PT) test to evaluate the cause of a coagulation defect if any.
You will get the reports after 6 hours, after the collection of the blood sample.
The cost of the Activated Partial Thromboplastin Time (aPTT) test is Rs. 550.
The Activated Partial Thromboplastin Time (aPTT) test is prescribed by your doctor after a complete assessment of your symptoms and conditions.
