Rapid detection of anticardiolipin antibodies [PDF]
American Journal of Hematology, 1998 A rapid screening method for the detection of antiphospholipid antibodies is described. Dense, red dyed polystyrene beads coated with cardiolipin were incubated with test sera for a short period of time, then added to a microtube containing anti-human IgG in a gel provided within a pre-cast card (DiaMed ID Microtyping System).
