High lupus anticoagulant in pregnant women suggests that stillbirths, unexplained habitual abortions, and intrauterine fetal growth retardation may occur, requiring definitive diagnosis and targeted treatment. Lupus anticoagulant is closely related to antiphospholipid syndrome, systemic lupus erythematosus, arteriovenous vascular and pathological pregnancy, but lupus anticoagulant can also be found in individual healthy people, due to physiological hypercoagulable state in pregnant women, lupus anticoagulant ratio >1.1 is abnormal, suggesting that the patient may be stillborn, unexplained habitual abortion, intrauterine fetal developmental retardation and so on. Pregnant patients with high lupus anticoagulant levels need to be diagnosed and treated, such as induction of labor for stillbirths and cervical cerclage, bed rest, and injections of human chorionic gonadotropin or progesterone for unexplained miscarriages, depending on the patient’s condition. Drugs need to be used under the guidance of a physician, and it is recommended that pregnant patients with high lupus anticoagulant levels go to a regular hospital for detailed counseling to avoid delays.
