How can i tell the difference between babesia and bartonella symptoms?

You cannot: This is why medical training takes so long and there are multiple specialties. Babesia infections may actually be asymptomatic in many people. Assuming your are talking about bartonella henselae, the causative agent of cat scratch disease, the characteristic presentation is localized lymphatic enlargement and discomfort proximal to the cat scratch. There are other species of bartonella.

Testing: As stated by other doctors, I don't think that you would necessarily be able to diagnose either accurately based on symptoms alone. There are tests for Babesiosis: Babesia PCR, Babesis FISH, B. Duncan IgM & IgG IFA, B. microti IgM & IgG IFA. Tests: Bartonella FISH, Bartonella IFA, Bartonella PCR, Bartonella multi- species western blot.
