Background: Antiphospholipid antibody syndrome (APS) is characterized by laboratory
evidence of antiphospholipid antibodies (aPL)[eg lupus anticoagulant (LA), anticardiolipin …

Even though routine screening of the general hospital population is discouraged, medical
laboratories may use a “lupus sensitive” activated partial thromboplastin time test (aPTT) …

Objectives Lupus anticoagulant (LA) detection requires (1) prolongation of a phospholipid
(PL)–dependent clot-based screening assay,(2) noncorrection upon adding normal pooled …

The laboratory diagnosis of the antiphospholipid syndrome (APS) via antiphospholipid
antibody (aPL) tests, including lupus anticoagulant (LAC), anticardiolipin (aCL), or anti …

INTRODUCTION: Accurate and timely detection of lupus anticoagulants (LA) is of diagnostic
and prognostic importance due to the association of persistent LA with thrombotic disease …

Sir, Diagnosis of the antiphospholipid syndrome (APS) is based on clinical criteria in
combination with the presence of antiphospholipid (aPL) antibodies. 1 Laboratory tests …

Lupus anticoagulant (LA) is composed of heterogeneous autoantibodies, which have a
close association with thrombotic events. Due to its heterogeneity, two methods for …

The authors have evaluated two commercial assays for lupus anticoagulants (LA), the
DVVtest+ DVVconfirm (American Diagnostica, Greenwich, CT) and the PTT-LA+ Staclot LA …

Objective: To determine whether the diagnosis of lupus anticoagulant (LAC) in a large
cohort of positive patients was confirmed at a reference laboratory. Methods: Over a 1‐year …

Lupus anticoagulants (LA) rarely affect routine prothrombin time assays because the high
phospholipid (PL) content in thromboplastin reagents tends to overwhelm the antibodies …
