Comparison of three rapid methods for detection of antibodies to streptolysin O and DNase B.

Department of Clinical Laboratory Science, School of Allied Health Science, Temple University, Philadelphia, Pennsylvania 19140.

ABSTRACT

Three commercial systems were compared for ability to detect antibodies to streptolysin O (ASO) and DNase B (ADB). Streptozyme (Wampole Laboratories, Cranbury, N.J.) exhibited high sensitivity (100%) for detecting ASO but low sensitivity for ADB (22.2%). The LeapStrep (Organon Teknika, Malvern, Pa.) and Check-Spectra (Diagnostic Technology, Hauppauge, N.Y.) tests had low sensitivities for detecting ASO (35.3 and 21.4%, respectively) and ADB (22.2 and 33.3%, respectively).
