lupus anticoagulant factor

Abnormal kaolin PTT cannot be corrected with normal plasma, suggesting the presence of an inhibitor. The platelet phospholipid neutralization test for detecting lupus anticoagulant factor is positive. This anticoagulant factor can cause prolongation of kaolin PTT in vitro and is associated with thrombosis tendency in vivo. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Found in systemic lupus erythematosus. Tips: Do not wear clothes that are too small or too tight, so as to avoid the sleeves being too tight when blood is drawn or the sleeves are too tight after blood drawing, causing blood vessels in the arms. Normal value negative. Clinical significance Abnormal result Positive in systemic lupus erythematosus, rheumatoid arthritis, hairy cell leukemia, malignant lymphoma, bacterial or viral or protozoal infection, skin malignancy, thrombosis, application of chlorpromazine, quinidine and antibiotics. Need to check the population suspected of the above patients. Positive results may be diseases: anti-phospholipid syndrome in children, pharyngeal lupus precautions Inappropriate people: generally no special population. Taboo before the examination: It is necessary to cooperate with the doctor to write the correct name, neat and tidy, to avoid confusion caused by the same name or similar names. With these in mind, blood draws are more convenient and faster, and you can better save yourself time for diagnosis. Requirements for inspection: Do not wear clothes that are too small or too tight in cuffs to avoid the sleeves being too tight when blood is drawn or the sleeves are too tight after blood drawing, causing blood vessels in the arms. Different laboratory items should be asked by the doctor and treated differently. Inspection process The modified Russell venom dilution test, including two experimental contents 1 Lupo test II, when the snake venom test is prolonged, after adding normal mixed plasma, the venom test is still prolonged, suggesting that there is lupus anticoagulant in the tested plasma. 2Lucor test phospholipids can neutralize lupus anticoagulant substances, so that the clotting time is shortened or normal, more specific and simple proof of the presence of lupus anticoagulant. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally not.
