Partial Thromboplastin Time (Definition)

The time required for clot formation in blood plasma after activation and addition of platelet particles such as phospholipids. The test called PTT or aptt is used to assess the coagulation pathways or clotting pathways in your blood. A prolonged aptt can indicate a deficiency of a component of the clotting pathways, such as factors xii, xi, ix, viii, x, v, ...Read more

Needs follow-up: Prolonged PTT can be a transient phenomenon after "viral" infection. Expected normalized within 6 weeks. If prolongation persists beyond that period, further work-up would be prudent. ...Read more

Will it make you tired if ptt levels are too low as in below a 1?

Will it make you tired if ptt levels are too low as in below a 1?

Other way.: Tired lowers your ptt level. Specifically, the inflammatory state that makes one tired is activating delta (deep sleep) waves in the brain in a way that is one of extremely few inflammatory pathways that aspirin DOES NOT BLOCK. Inflammation triggers liver production of clotting proteins lowering PTT. Steroids inhibit all these inflammatory pathways. ...Read more

Please tell me what does an elavated ptt mean and why do you need an hematology/oncologist for that?

Please tell me what does an elavated ptt mean and why do you need an hematology/oncologist for that?

Many causes: Ptt is a screening test that tests for the status of multiple coagulation factors in blood. There are a variety of reasons for prolonged PTT results. Typically, the possibilities are addressed by hematologists and can be due to factor deficiencies (acquired or genetic) or to inhibitors. Some factor deficiencies (xi, ix, viii) identified by PTT prolongation cause bleeding. Some (xii) do not. ...Read more

Pt/inr normal, ptt, activated is 3 seconds prolonged, and in the lupus anticoagulant panel, only abnormality is aptt at 41.4 sec. What does this mean?

Any symptoms?: Why were these tests done? Do you have any symptoms? All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. A slightly prolonged PTT in isolation is not a cause for concern, but it would be important to know why your doctor ordered the tests. Lupus is one of the causes of prolonged ptt. ...Read more
