Part Description

LP16720-2   Legionella pneumophila
Legionella pneumophila, a gram-negative bacillus, most commonly causes acute pneumonia (legionellosis). Transmission to humans is usually through aerosols of infected water sources such as fountains, misting systems, and drinking water. Severity of infections due to L. pneumophila range from mild (walking pneumonia) to fatal (multilobar pneumonia). Antimicrobial therapy usually includes erythromycin, with the addition of rifampin in severe cases. Initial response to therapy is usually rapid, but full recovery can take weeks to months.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
