Original price was: ₹550.00.Current price is: ₹400.00.

the Activated Partial Thromboplastin Time (aPTT) test, also known as Partial Thromboplastin Time (PTT), is a blood test that measures how long it takes for blood to clot, assessing the function of certain blood clotting factors in the intrinsic and common pathways of the coagulation cascade. 

Here’s a more detailed explanation:
  • What it measures:
    The aPTT/PTT test measures the time (in seconds) it takes for a clot to form in a blood sample after specific reagents are added. 

  • Why it’s used:
    It helps evaluate a person’s ability to form blood clots appropriately and can be used to:

    • Monitor the effectiveness of heparin, a blood-thinning medication. 
    • Detect bleeding or clotting disorders. 
    • Identify deficiencies in certain blood clotting factors. 
  • How it’s performed:
    A blood sample is drawn, and the time it takes for the blood to clot is measured in seconds. 

  • What the results mean:
    • A prolonged aPTT/PTT result (longer clotting time) may indicate a deficiency in one or more clotting factors, or the presence of a bleeding disorder, or the effect of heparin. 
    • A shorter-than-normal aPTT/PTT result (faster clotting time) can also occur and may indicate a higher risk of blood clots. 
  • Other names:
    Activated partial thromboplastin time (aPTT), partial thromboplastin time (PTT), Kaolin-cephalin clotting time (KCCT).
