In 11/2014 I was hospitalized with bilateral PE. 3 lupus anticoagulant tests have come back positive, and he said it's primary. Does that mean APS?

What do these mean? lupus anticoagulant weakly present at 1.30; positive ANA Test 1:40 speckled pattern; negative anticardioliptin and beta2

Not much: A weakly present lupus anticoagulant and an ANA of 1:40 are common in the general population, and usually not an indication of an autoimmune disorder. You should visit with the physician who ordered these tests to review them with you however. A test alone does not give any answers. Doctors will need both a patient's history and tests to determine further management. ...Read more

Anticoagulants are any of a variety of drugs which decrease the body's ability to make or sustain blood clots. They fall, generally, into two categories.
