Measured in seconds to clot formation, normal PTT can vary based on laboratory or institution; however, normal PTT is between 25 to 35. PTT ranges are used to classify heparin dosing schemes as low or high intensity and to ensure effective dosing.
What is the PTT normal range?
The reference range of the PTT is 60-70 seconds. In patients receiving anticoagulant therapy, the reference range is 1.5-2.5 times the control value in seconds. Critical values that should prompt a clinical alert are as follows: aPTT: More than 70 seconds (signifies spontaneous bleeding)
Why is high PTT bad?
This could cause heart attacks, strokes, or other problems. Too much can cause heavy bleeding. Have unexplained blood clots: Your doctor may order the PTT test to help diagnose a specific immune system disorder that can cause clots. In pregnant women, the disorder can lead to miscarriages and other problems.
