Test Details

Test Includes

Activated partial thromboplastin time (aPTT); anticardiolipin antibodies, IgG, IgM; β2-glycoprotein I, IgA, IgG, IgM; dilute Russell's viper venom time (dRVVT); hexagonal phospholipid neutralization; international normalized ratio (INR); lupus anticoagulant interpretation; platelet neutralization; prothrombin time; thrombin time

Immediate reflex to aPTT Mixing Studies [117199] if aPTT is five or more seconds above the upper end of the reference interval.

Methodology

Clot; enzyme-linked immunosorbent assay (ELISA)

Specimen Requirements

Specimen

Plasma and serum, frozen

Volume

Three 2-mL citrated plasma tubes and 2 mL serum

Container

Blue-top (sodium citrate) platelet-free plasma tubes and red-top tube or gel-barrier tube

Collection

Plasma/serum must be separated from cells within 45 minutes of venipuncture. Send plasma/serum in plastic transport tubes. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Storage Instructions

Freeze.
