Lupus anticoagulant. Lupus anticoagulant is an immunoglobulin [1] that binds to phospholipids and proteins associated with the cell membrane. Its name is a partial misnomer, as it is actually a prothrombotic antibody in vivo. The name derives from their properties in vitro, as these antibodies increase coagulation times in laboratory tests such ...
Kaolin clotting time. Test of. Blood plasma [1] Kaolin clotting time (KCT) is a sensitive test to detect lupus anticoagulants. [2] There is evidence that suggests it is the most sensitive test for detecting lupus anticoagulants. [3] It can also detect factor VIII inhibitors but is sensitive to unfractionated heparin as well.
2–7 per 10,000 [2] Lupus, technically known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. [1] Symptoms vary among people and may be mild to severe. [1] Common symptoms include painful and swollen joints, fever, chest pain, hair ...
T-cells are white blood cells that play a key role in the body’s immune response. The study arrived at its findings by comparing blood samples from 19 people with lupus to blood samples from ...
Russell's viper, Daboia russelii Dilute Russell's viper venom time (dRVVT) is a laboratory test often used for detection of lupus anticoagulant (LA). It is an assessment of the time for blood to clot in the presence of a diluted amount of venom from Russell's viper (Daboia russelii), a highly venomous snake native to the Indian subcontinent and named after the herpetologist Patrick Russell.
Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. [1] Symptoms of these diseases can affect many different body systems, including joints, skin, kidneys, blood cells, heart, and lungs. The most common and most severe form is systemic lupus erythematosus.
Mixing studies are tests performed on blood plasma of patients or test subjects to distinguish factor deficiencies from factor inhibitors, such as lupus anticoagulant, or specific factor inhibitors, such as antibodies directed against factor VIII. [1] Mixing studies are screening tests widely performed in coagulation laboratories.

Undifferentiated connective tissue disease (UCTD) (also known as latent lupus or incomplete lupus[1]) is a disease in which the connective tissues are targeted by the immune system.
