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 more than three seconds above the upper end of the reference interval)
Expected Turnaround Time
5 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
