Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
The partial thromboplastin time (PTT), also known as the 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 ), [ 1 ] reflecting kaolin and cephalin as materials historically used in the test.
Pregnancy after the age of 35 augments the risk of VTE, as does multigravidity of more than four pregnancies. [2] Pregnancy in itself causes approximately a five-fold increased risk of deep venous thrombosis. [6] Several pregnancy complications, such as pre-eclampsia, cause substantial hypercoagulability. [2]
The aPTT-based APC resistance test involves a modified aPTT test performed in the presence and absence of activated protein C (APC). [1] [5] The ratio of these aPTT values is calculated and is called the APC sensitivity ratio (APCsr) or simply APC ratio (APCr). [1] [5] This ratio is inversely related to the degree of APC resistance. [7]
[4] [10] The prolongation of the activated partial thromboplastin time should completely correct with a 1:1 mixing study with normal plasma if haemophilia C is present; in contrast, if a lupus anticoagulant is present as the cause of a prolonged aPTT, the aPTT will not correct with a 1:1 mixing study.

Treatment for a lupus anticoagulant is usually undertaken in the context of documented thrombosis, such as extremity phlebitis or dural sinus vein thrombosis. Patients with a well-documented (i.e., present at least twice) lupus anticoagulant and a history of thrombosis should be considered candidates for indefinite treatment with anticoagulants.
