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 Gram positive bacteria identified. It is commonly used with the system or sample type Bld.pos growth.

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: Observation
  • Method: Probe

What it does not mean

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

Key facts

  • Gram positive bacteria identified [Interpretation] by Probe in Positive blood culture
  • Gram positive bacteria identified
  • Gram-positive (GP) bacteria identified positive blood cultures. This term was created for, but not limited in use to, Nanosphere's Verigene Gram-Positive Blood Culture test (BC-GP), which uses microarray analysis with probe to identify gram-positive bacteria, including Staphylococcus spp., S. aureus, S. epidermidis, S. lugdudensis, Streptococcus spp., S. pyogenes, S. agalactiae, S. anginosus group, S. pneumoniae, E. faecalis, E. faecium, and Listeria spp. as well as the mecA, vanA, and vanB genes.
