  • a Positive (Pos) and negative (Neg) test results are shown. The positivity rate of the MagNA Pure LC system was 27.9% (157 of 563 swabs), and the 95% confidence interval was 24.2 to 31.8%. The positivity rate of SETS was 31.8% (179 of 563 swabs), and the 95% confidence interval was 28.0 to 35.8%. The positivity rates of the two methods were significantly different (P < 0.0001) by the sign test.
