# Bartonella Testing: Detection for Elusive Infections ##### Comprehensive Tools for Complex, Persistent Cases _Bartonella_ is a stealth pathogen that replicates slowly, cycles through the bloodstream every few days, and hides deep in tissues, making it one of the most difficult to detect pathogens. Its ability to evade the _immune_ response and mimic neurological, vascular, and psychiatric conditions often leads to misdiagnosis or missed diagnosis altogether. Galaxy Diagnostics combines advanced molecular and serological tools to detect _Bartonella_ where traditional tests fall short, bringing clarity to complex, chronic cases. [Order Bartonella Testing](/content/order/index.html) ## The Diagnostic Challenge of _Bartonella_ _Bartonella_ infections can affect multiple body systems and present with a wide range of symptoms. Because the organism circulates intermittently and replicates only once approximately every 24 hours, timing of collection is critical. Traditional PCR and serology weren’t built for pathogens like _Bartonella_, which cycle through the bloodstream and retreat into tissues between episodes. This intermittent behavior makes it easy to miss, even in symptomatic patients. _Bartonella’s_ low abundance and cyclical pattern make single tests unreliable. Serial and combined testing improves the odds of detection. ## Galaxy’s Direct Detection: Digital PCR Galaxy’s **Digital PCR** is a genus-level, multiplexed assay that detects _Bartonella_, _Babesia_, and _Borrelia_ DNA directly from blood with exceptional precision. Galaxy’s proprietary method leverages digital PCR with targeted culture enrichment for _Bartonella_ using BAPGM media, boosting detection sensitivity through thousands of micro reactions. This process dramatically improves the sensitivity of detection, allowing identification of pathogens even at **extremely low DNA copy numbers** that traditional PCR misses. Unlike standard qPCR, which analyzes one sample at a time, digital PCR partitions the sample into thousands of micro-reactions, enabling deeper detection of pathogens that circulate intermittently or fall below the limits of conventional assays.
