Legionella pneumophila Ag [Presence] in Tissue by Immunofluorescence
L pneumo Ag Tiss Ql IF
Definition
- Immunofluorescence testing of lung biopsy specimens for Legionella pneumophila antigen has over 99% specificity, but only 25-70% of patients with culture-positive disease test positive for the antigen. Therefore, IF cannot be used to rule out Legionella infection, but a positive result is nearly always diagnostic. [http://www.who.int/water_sanitation_health/emerging/legionella.pdf]
