73833-6Legionella sp Ab [Presence] in Specimen by ImmunofluorescenceActive

Term Description

Legionella bacteria in various patient specimens (lung tissues, respiratory tract fluids, and cultures) can be detected by immunofluorescent assays. This codes was created for, but not limited in use to, the submitter's test kit, Zeus Scientific's Legionella DFA Test system. Results are based on the number of typical bacilli observed along with the intensity of bacterial cell wall fluorescence observed. Cultures that are morphologically typical and brightly fluorescent (3+ to 4+) are considered positive.
