What does PTT mean in HOSPITALS

Partial Thromboplastin Time (PTT) is a test that measures the clotting ability of blood. It involves using chemicals or pure tissue factor from human sources to initiate a coagulation reaction in a sample of blood and measuring how long it takes for the sample to form clots.

When PTT tests are done, certain chemicals or pure tissue factor from human sources are added to the patient's blood sample. This initiates a coagulation reaction and the time it takes for clots to form is measured. If it takes longer than usual then there may be an abnormality with the patient's clotting system.

PTTS can be used to diagnose various bleeding and clotting disorders, as well as monitor how effective anticoagulants like heparin are working. It can also provide information on platelet function and platelet count which helps guide treatment decisions if further tests are needed.

PTTS tend to be very accurate when done correctly but some factors such as recent surgeries or certain medical conditions may affect results. For best accuracy, it's important to follow all instructions given by your doctor when preparing for this test, including fasting for 12 hours prior if instructed.

Anyone diagnosed with abnormal bleeding or clotting issues could benefit from having a partial thromboplastin time test done. Additionally, people who take anticoagulant medications such as heparin should have their PTT monitored regularly because these drugs can affect their coagulation status over time.
