The Lupus Anticoagulant test report focuses on the Lupus Anticoagulant Ratio. Lupus Anticoagulant is an autoantibody against a variety of negatively charged phospholipid-protein complexes, a type of antiphospholipid antibody, and its testing usually consists of screening, confirmatory, and mixed tests. The lupus anticoagulant ratio is the lupus anticoagulant screening test detection value/confirmatory test detection value, and the normal reference value is usually 0.8 to 1.2. An elevated lupus anticoagulant ratio suggests the presence of lupus anticoagulant. Therefore, the lupus anticoagulant test report focuses on the ratio. Elevated lupus anticoagulant ratio can be seen in female patients with autoimmune diseases, immune thrombocytopenia, true erythrocytosis, malignant tumors, hepatitis and normal people, while the mixing test is to test the clotting time after mixing the patient’s plasma with normal people’s plasma 1:1, which can mainly exclude the effect of coagulation factor deficiency. If the lupus anticoagulant ratio is found to be too high, it is recommended to go to the rheumatology and immunology department, hematology department and other related departments of regular hospitals for detailed examination and targeted treatment after clarifying the cause of the disease.
