What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Bartonella sp DNA. It is commonly used with the system or sample type Tiss.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: Probe.amp.tar

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Bartonella sp DNA [Presence] in Tissue by NAA with probe detection
Bartonella sp DNA
Several species of Bartonella have been associated with culture-negative endocarditis, with B. henselae and B. quintana being most common. Because cultures are sterile, diagnosis relies on other methodologies such as molecular techniques. [PMID11897074] Such infections may involve native or prosthetic valves.
