You assume they just float about willy nilly, and will be in the sample
under examination. Not so.

They could be elsewhere, but causing a systemic immune activation, the
way roundworms, for example, do.
My child was cured of longstanding tick borne diseases with an empiric
trial of anti parasitic meds for presumed babesiosis. Babesia are very
hard to find in serum and tissue, especially after the acute phase,
though they can be passed along in blood donation.
