When the doctor order cocci serology and species antibodies bartonella, what he expected to find?lupus?lyme diseases?

Bartonellosis: Several variants. Cat scratch fever, carrion's, some endocarditis syndromes. Hope it's not bacillary angiomatosis -- or if it is, that you get effective rx. Good luck.

Lab tests: If he ordered Bartonella antibodies he may have been thinking about Cat scratch disease, Carrion’s disease (Oroya fever & verruga peruana) or Trench Fever. Cocci may be for coccidioidomycosis (AKA valley fever/ Desert fever). Ask the doctor directely.
