Passing biofilms would most likely be a very good thing if it is in response to your treatments. It could mean your immune system is working and/or the treatments are working to rid your gut of various infections which often live in biofilm communities.
Perhaps one of your treatments contains a biofilm eradicator and various antimicrobials.
It would be helpful to know exactly what treatments you are using.
FYI: there is an excellent video by Dr Flechas, on UTube, in which he describes a study done by the Mayo Clinic in which they cured numerous Lupus patients using DHEA hormone. These patients were severely deficient in this hormone.
