Lupus anticoagulant (LA) – modified coagulation test. * The cardiolipin antibody is commonly found in individuals suffering from collagenoses.

Streptococcal antibody is an antibody against the bacterial species Streptococcus. These can be divided into α-, β-, and γ-streptococci. The β-streptococci can in turn be subdivided into groups A through W. The best known are: Streptococcus pyogenes (group A) – especially in scarlet fever, pharyngitis (pharyngitis) or erysipelas (erysipelas). Streptococcus agalactiae (group B) – especially … Streptococcal Antibodies
