Can Genova give false negatives for parasites?

Has anyone had false negatives with Genova Diagnostics?
I recently got back a comprehensive digestive stool analysis from Genova which says I have no yeast, and no parasites, but I do have some bad bacteria. The thing is I still see what I am virtually sure is candida and hookworms. The test also indicates I have malabsorption problems, which could be caused by the bad bacteria. And pancreatic enzyme deficiency - which I cannot figure out another reason for besides parasites. I guess my plan for now should be to fight what I know? This is my bacteriology results:
Good - lactobacillus 2+, E Coli 4+, Bifidobacterium 2+
Bad - alpha haemolytic Streptococcus 3+, Citrobacter freundii 4+, Enterobacter cloacae 2+.

Has anyone had success fighting these pathogens? Has anyone gotten false negatives from Genova? Thanks!
