What does aPTT stand for in medical terms?

The partial thromboplastin time ( PTT) or activated partial thromboplastin time ( aPTT or APTT) is a blood test that characterizes coagulation of the blood. A historical name for this measure is the kaolin-cephalin clotting time ( KCCT ), reflecting kaolin and cephalin as materials historically used in the test.

What does a high activated partial thromboplastin time aPTT mean?

A high activated partial thromboplastin time (aPTT) in a blood test means a bleeding disorder. It may be due to congenital deficiencies, DIC or anticoagulant therapy treatment. Blood test

What is the normal range of aPTT?

A typical value for a PTT is 60 to 70 seconds. There’s also an activated PTT (aPTT) test that measures the same thing, but they add a substance to your blood to make it clot faster. ... A typical aPTT value is 30 to 40 seconds.

How are the results of the aPTT blood test given?

Because clotting functions are being measured with the APTT blood test, the results given by a laboratory are typically given in time intervals. Normal results are based on the way each laboratory measures the clotting factors.

What does aPTT stand for?

activated partial thromboplastin time (APTT, aPTT) the period required for clot formation in recalcified blood plasma after contact activation and the addition of platelet substitutes such as brain cephalins or similar phospholipids; used to assess the coagulation pathways.

What does shortened activated partial thromboplastin time (aPTT) mean?

A shortened activated partial thromboplastin time (aPTT) has no diagnostic meaning, but it may be due to extensive cancer, when the liver is not involved or after an acute hemorrhage. Where can I find more information about activated partial thromboplastin time (aPTT) in a blood test?

What is the normal range of APTT in blood test?

Activated partial thromboplastin time (aPTT) in a blood test is age-dependent: Adults: 20 - 38 seconds Children from 11 to 16 years old: 33.9 - 46.1 seconds Children from 6 to 10 years old: 31.8 - 43.7 seconds

What does a prolonged aPTT indicate?

A prolonged aPTT can indicate a deficiency of any of various coagulation factors, including factors XII, XI, IX, VIII, X, V, and II, and fibrinogen. AEC minimal response time the shortest duration at which x-ray exposure can be terminated by automatic exposure control.

Some studies suggest that a low aPTT time increase the possibility of thrombosis or. This may be because a low aPTT time is seen in case of extensive cancer or severe bleeding. Which factors can reduce the activated partial thromboplastin time (aPTT) in a blood test?

What is the normal range of APTT in blood test?

Activated partial thromboplastin time (aPTT) in a blood test is age-dependent: Adults: 20 - 38 seconds Children from 11 to 16 years old: 33.9 - 46.1 seconds Children from 6 to 10 years old: 31.8 - 43.7 seconds

What is the normal value of activated partial thromboplastin time (aPTT)?

What is the normal value of activated partial thromboplastin time (aPTT) in a blood test? Activated partial thromboplastin time (aPTT) in a blood test is age-dependent: Adults: 20 - 38 seconds Children from 11 to 16 years old: 33.9 - 46.1 seconds

What is the normal range for a PTT?

A typical value for a PTT is 60 to 70 seconds. There’s also an activated PTT (aPTT) test that measures the same thing, but they add a substance to your blood to make it clot faster. A typical aPTT value is 30 to 40 seconds.

What does a low aPTT time indicate?

An activated partial thromboplastin time (aPTT) lower than the control sample is not diagnostically significant, but it may be a clue reflecting hypercoagulability. Some studies suggest that a low aPTT time increase the possibility of thrombosis or. This may be because a low aPTT time is seen in case of extensive cancer or severe bleeding.
