What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

Gram negative bacteria identified [Interpretation] by Probe in Positive blood culture

Gram negative bacteria identified

Gram-negative (GN) bacteria identified in positive blood cultures. This term was created for, but not limited in use to, Nanosphere's Verigene Gram-Negative Blood Culture test (BC-GN), which uses microarray analysis with probe to identify gram-negative bacteria, including Acinetobacter sp, Citrobacter sp, Enterobacter sp, Proteus sp, Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, and Pseudomonas aeruginosa, as well as the six antibiotic resistance gene markersCTX-M, KPC, NDM, VIM, IMP, OXA.
