title: [Increased sensitivity of the parapertussis diagnostic agent].
abstract: The adsorption activity of formolated sheep red blood cells can be increased by their combined treatment with low-frequency ultrasound, tannin and Tween-40. The diagnosticums thus obtained have proved to be highly sensitive and specific and can be recommended for the detection of antibodies to Bordetella parapertussis in the sera of sick children.
