a
Purified IgA samples were serially diluted and evaluated by ELISA for secretory component. The IgA concentration of the highest dilution for each sample giving a positive signal is listed.
b
Endotoxin levels present in unpurified representative vaginal and rectal swabs are listed for comparison.
NT = Not Tested
