TABLE 3.

Comparison of C_T values obtained with traditional and ESwab collection devices for each of the four analytes in the SA Complete assay

Target	No. of specimens^a	Traditional swab		ESwab		t test P value^b
Target	No. of specimens^a	Avg C_T	SD of C_T	Avg C_T	SD of C_T	t test P value^b
SPC (internal control)	147	34.64	1.90	33.64	1.20	1.42 × 10⁻⁷
S. aureus protein A	60	25.43	4.91	25.40	5.10	0.98
mecA gene	140	29.93	4.20	29.73	4.55	0.71
SCC cassette	13	25.86	4.90	26.12	6.41	0.91

These values only included specimens that had an actual C_T value with both the traditional and ESwab collection devices (the SPC does not need to amplify in specimens that are positive for S. aureus, mecA, or the SCC cassette.

Significant at a value of <0.05.
