Diphtheria antibody standardization

[GEORGE CARLONE]

We are interested in comparing protocols and standard reagents for 
quantifying diptheria serum antibody after vaccination.  We are
planning a multilab study to determine how well different protocols,
standard reagents, and methods of data analysis compare to one another.
Please contact me if you are currently measuring diptheria serum antibody
using a validated standardized assay (ELISA, vero cell, other) and would
like to participate.
