What does a PTT blood test show?
A partial thromboplastin time (PTT) test measures the time it takes for a blood clot to form. Normally, when you get a cut or injury that causes bleeding, proteins in your blood called coagulation factors work together to form a blood clot.
Is INR and PTT the same?
The prothrombin time (PT) test measures how quickly blood clots. The partial thromboplastin time (PTT) is mainly used to monitor a person’s response to anticoagulant therapies. The international normalized ratio (INR) calculation helps ensure that PT test results are standardized and accurate.
What does it mean when your PTT is 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 happens if PTT is low?
Low levels of clotting factors can prevent a clot from forming. A deficiency in clotting factors can lead to symptoms such as excessive bleeding, persistent nosebleeds, and easy bruising.
How much does aPTT test cost?
On MDsave, the cost of a Prothrombin Time (PT)/INR ranges from $4 to $40. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.
What blood disorders cause clots?

- Deep Vein Thrombosis (DVT)
- Pulmonary Embolism (PE)
- Arterial Thrombosis.
- Antiphospholipid Antibody Syndrome (APLS)
- Factor V Leiden.
- Prothrombin Gene Mutation.
- Protein C Deficiency, Protein S Deficiency, ATIII Deficiency.
How is PTT test done?
To perform the test, the phlebotomist or nurse takes a sample of blood from your arm. They clean the site with an alcohol swab and insert a needle into your vein. A tube attached to the needle collects the blood. After collecting enough blood, they remove the needle and cover the puncture site with a gauze pad.
How long is a PTT good for?
Specimens are stable at room temperature for 24 hours. If testing cannot be completed within 24 hours, specimens should be centrifuged for at least 10 minutes at 1500xg.
Do I need to fast for PTT test?

What medications can cause blood clots?
24, 2014 (HealthDay News) — People who use painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs) — which include aspirin, naproxen (Aleve) and ibuprofen (Advil, Motrin) — may be at increased risk for potentially deadly blood clots, a new study suggests.
What is a PTT test for coagulation?
A PTT test checks the function of specific coagulation factors. These include factors known as factor VIII, factor IX, factor X1, and factor XII. Other names: activated partial thromboplastin time, aPTT, intrinsic pathway coagulation factor profile What is it used for? A PTT test is used to: Check the function of specific coagulation factors.
What triggers a PT and PTT blood test?
The potential presence of a blood clot in a vein or an artery will also trigger this test, as well as the rapid bleeding and clotting factors that get used at unusually high rates. Some individuals who suffer from chronic liver disease may also have the PT and PTT blood test ordered to determine their hemostasis status.
What do my PT and PTT results mean?
When combined together, these PT and PTT results may indicate these common conditions. Prolonged PT, Normal PTT: Indicates a vitamin K deficiency, decreased/defective factors, or liver disease.
Can anticoagulants cause a prolonged PTT test result?
There are certain anticoagulants that will not cause a prolonged PTT blood test result. Your medical provider will let you know if these are present and if they should be monitored through other forms of testing in addition to the PT and PTT blood tests.
