What about calculating a positron asymmetry?  In general, couldn't you have:

A_tot = A_e(-) + A_e(+)

where A_tot = total electron asymmetry with some contamination, A_e(-) =
electron asymmetry, A_e(+)  = positron asymmetry.

I would think that calculating A_e(+) != 0 would indicate some level of
contamination that could be subtracted off from your current electron
asymmetry.
