title: [Improvement of the IgM-FTA-ABS Test--Short Communication (author's transl)].
abstract: With immobilized Protein A from Staph. aureus, treponema-specific IgG can be removed from patient's serum by affinity chromatography. The IgM-FTA-ABS-test can be improved decisively by eliminating competition at the antigen of treponema-specific IgM and IgG and thus false negative results.
