Overview
The are no laboratory findings characteristic of listeriosis.
Laboratory Findings
For symptomatic patients, diagnosis is confirmed only after isolation of Listeria monocytogenes from a normally sterile site, such as blood, spinal fluid, or amniotic fluid/ placenta.[1]
Listeria monocytogenes can be readily isolated on routine media, but care must be taken to distinguish this organism from other Gram-positive rods, particularly diphtheroids. Selective enrichment media improve rates of isolation from contaminated specimens.[1]
