Lupus anticoagulant (LA)
The test detects lupus anticoagulant — an autoantibody affecting the blood coagulation system. Used for antiphospholipid syndrome diagnosis and when thromboses, miscarriages, or clotting disorders are suspected.
Biomaterial: Venous blood
Draw blood fasting 8-12 hours; exclude fatty food and alcohol 24 hours before; avoid stress and physical activity 30 minutes before. Inform physician of anticoagulant or coagulation-affecting drug intake.
- Recurrent venous or arterial thromboses;
- frequent spontaneous miscarriages;
- suspected antiphospholipid syndrome;
- blood clotting disorders;
- positive ANA or other autoimmune marker results.
Negative — lupus anticoagulant not detected.
Positive — lupus anticoagulant detected; indicates elevated thrombosis risk; physician consultation required.
Note: Positive result is not a diagnosis; final assessment conducted by physician.
