clubroot confirmation

I believe this may have come up once already but will risk repeating an inquiry:

Does anyone have a serological assay for Plasmodiophora brassicae?  Or some
other means of confirming infection in asymptomatic plants?  I can see the
plasmodia in roots with no symptoms and would like some other means of
confirming the diagnosis without having to wait for clubs to form.

Any help would be appreciated.
