What is a normal PTT value?
Normal PTT values can vary between laboratories but 25 to 35 seconds is considered normal.
What is considered a high PTT level?
A typical aPTT value is 30 to 40 seconds. If you get the test because you’re taking heparin, you’d want your PTT results to be more like 120 to 140 seconds, and your aPTT to be 60 to 80 seconds. If your number is higher than normal, it could mean several things, from a bleeding disorder to liver disease.
What is abnormal PTT?
Abnormal values A longer-than-normal PTT or APTT can mean a lack of or low level of one of the blood clotting factors or another substance needed to clot blood. This can be caused by bleeding disorders, such as hemophilia or von Willebrand’s disease.
What is therapeutic PTT?
PTT detects nearly all abnormalities in clotting, due to deficiencies in clotting factors or circulating anticoagulants. It is frequently used to monitor heparin therapy. A modification of the test, “Activated PTT,” or APTT, is basically the same as PTT, but is slightly more sensitive.
Why is PTT high?
An abnormal (too long) PTT result may also be due to: Bleeding disorders , a group of conditions in which there is a problem with the body’s blood clotting process. Disorder in which the proteins that control blood clotting become over active ( disseminated intravascular coagulation ) Liver disease.
What is the normal value for aPTT?
A normal range is around 21 to 35 seconds. But test results will vary depending on equipment and methods used. So standard normal results will differ in each lab. If your aPTT takes longer than normal, it may mean several things.
What is PTT test used for?
The PTT is used primarily to investigate unexplained bleeding or clotting. It may be ordered along with a prothrombin time (PT/INR) to evaluate the process that the body uses to form blood clots to help stop bleeding.
What is the normal range of coagulation?
The normal range for clotting is: 11 to 13.5 seconds. INR of 0.8 to 1.1.
