The Partial Thromboplastin Time (PTT) Test checks how well your blood forms clots. You may also hear it called aPTT or activated partial thromboplastin time. If your doctor ordered this, you can book at participating labs on LabFinder.
This test, also called partial thromboplastin time or PTT, measures the time it takes your blood to clot. It helps your doctor see if certain clotting proteins are low, missing, or slowed down by medicine.
Common reasons: easy bruising or frequent nosebleeds, bleeding longer than expected after a cut, checking clotting before surgery, monitoring heparin treatment, or looking into possible clotting factor problems or autoimmune clotting issues.
You will check in, show your ID and order, and sit in a draw chair. A phlebotomist cleans your skin, places a small needle, and fills one or more tubes with blood. Pressure and a bandage are placed on the spot. Most visits take about 15 to 30 minutes, and the actual draw is only a few minutes.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. If you are on heparin, the timing of the draw matters, so follow the timing your doctor gives.
Medications: bring a list of all medicines and supplements, and ask your doctor about the timing if you take heparin or other blood thinners. Food and drink: you can usually eat and drink as normal unless your doctor says otherwise. Activity: avoid hard exercise right before the draw. Hydration and clothing: drink water and wear a short sleeve top if you can. Always follow any extra instructions from your doctor or the center and bring past results if available.
Bleeding disorders such as hemophilia, conditions that cause easy bruising, effects of heparin treatment, autoimmune clotting problems like antiphospholipid syndrome, liver problems that affect clotting, and unexplained long bleeding after injuries. Results are read in context. Your doctor will review your numbers with your history and symptoms before planning next steps.
