What does the Babesia microti DNA test measure?

Why is Babesia microti DNA measured?

Real-time PCR detects Babesia microti DNA directly in whole blood, offering higher sensitivity than microscopy during early infection and in patients with low or intermittent parasitaemia. A positive result confirms active or recent infection and is the test of choice when clinical suspicion is high but blood films are negative. Because PCR amplifies nucleic acid, it can remain positive for a short window after successful treatment as dead or dying organisms clear, so repeat testing to document cure should be timed appropriately and interpreted alongside clinical improvement.

Functional medicine optimal

Not detected. Any detection of B. microti DNA indicates active or recent infection requiring clinical correlation and, in most cases, antimicrobial therapy.
