Determination of blood plasma leakage into feces and filter wick-sampled small intestinal secretions^a

OVA dose (mg)	% Contribution of blood plasma transudate to:
	Anti-OVA IgA titersb in:		Fluid vol sampled from jejunal surfacec
	Jejunal secretions	Feces
0.2	1.78 ± 3.55	0.84 ± 1.80	0.72 ± 0.74
2	1.35 ± 1.25	0.86 ± 0.40	0.59 ± 0.85
20	5.60 ± 9.53	0.89 ± 1.18	2.73 ± 3.10
All doses	2.91 ± 5.51	0.86 ± 1.10	1.35 ± 1.95

^aIndividual anti-OVA endpoint titers from three randomly selected animals of each OVA immunization group or all nine animals together were used to calculate the given data. No significant between-group differences could be detected for either sample or calculation mode (one-way ANOVA, P ≥ 0.364). 

^bPercentage of blood-borne specific IgA in the specific IgA content of the mucosal sample (calculated using equation 1). 

^cPercentage of the fluid volume sampled being blood plasma transudate (calculated using equation 2).
