Table 2. Immunobead test % binding (categorized)^*

	Bead Test Result
Sample	Normal	Positive	P Value

Control (n = 10)	5 (50%)	5 (50%)
1 day (n = 10)	2 (20%)	8 (80%)	.35
7 days (n = 10)	5 (50%)	5 (50%)	1.00
15 days (n = 10)	4 (40%)	6 (60%)	1.00
30 days (n = 9)	0	9 (100%)	.03 ${dagger}$

^*Percentage binding was categorized into 2 groups: 1) greater than 40% binding is a positive result, and 2) 40% or less binding is negative. Proportions of specimens in each experimental group with positive and negative results were compared with the control sample. (The 2 determinations per specimen from the immunobead test were averaged for use in the analysis.)
