 Thus The SSI Diagnostica ImmuView S .pneumoniae and L pneumophila urinary antigen test (UAT) was compared against two enzyme immunoassays (EIA) from Trinity Biotech and Binax for the detection of Legionella urinary antigen. Of 83 retrospective Legionella urinary antigen positives, 70 (84%) were also positive in the Immuview UAT, 8 (10%) were The use of urinary antigen tests (UATs) may provide early etiology in pneumonia, and facilitates rapid and directed antibiotic treatment. In this study, we evaluated the novel lateral flow ImmuView Streptococcus pneumoniae and Legionella pneumophila UAT, which detects pneumococcal and L. pneumophila serogroup 1 antigens in a combined test. The BinaxNOW pneumococcal urinary antigen (PNAG) test has been evaluated at laboratory level and is easy to perform and interpret, but its use as a point-of-care test has not been evaluated. A study was undertaken to assess whether PNAG testing can be reliably performed and interpreted by staff in an adult emergency department and whether rapid results influence initial treatment decisions. Only 1.1% was positive for Legionella pneumophila by urinary antigen test.
Indirect immunofluorescence is a serologic method used as a criterion for confirmation of acute legionellosis. Because of a paucity of studies using other serologic assays, the results are difficult to interpret. This test has demonstrated reasonable sensitivity and good specificity in different studies. 8-13 Nevertheless, the clinical usefulness of this pneumococcal urinary antigen test is not well defined, and, consequently, current guidelines do not clearly recommend the situations in which testing should be performed.

LD is an atypical pneumonia with symptoms ranging from mild disease to severe pneumonia The Xpect™ Legionella test is a rapid immunochromatographic test designed of Legionella pneumophila serogroup 1 and 6 antigens in human urine samples.

Urine antigen testing for pneumococcal pneumonia is recommended in current British Thoracic Society guidelines, whilst the National Institute for Health and Care Excellence and The American Thoracic Society and the Infectious Diseases Society of America guidelines consider its usage. A recent large prospective study found that patients who met IDSA/ATS guidelines for pneumococcal UAT infrequently had a positive result on testing (a positive test prevalence of 4.2%),
2016-10-01 · Urinary antigen tests (UAT) for Streptococcus pneumoniae and Legionella may be performed as part of the microbiological investigation for CAP. However, international guidelines are not unanimous regarding antibiotic reassessment in case of a positive UAT.

We performed urinary antigen tests for pneumococcus and Legionella for patients with community-acquired pneumonia (CAP), to prescribe a documented antibiotic therapy. We report the efficiency of low-spectrum antibiotic treatment, illustrating the inappropriateness of bacteriological respiratory sampling. Patients and methods: Patients with CAP were enrolled from three different units; the pneumonia severity index was used to assess the disease. Abstract.
Although pneumococcal vaccination in the United States has been recommended for adults aged >65 years since 1984 and for children since 2001, Streptococcus pneumoniae remains the most common bacterial cause of community-acquired pneumonia (CAP) and can be identified by blood cultures, sputum cultures, and urinary antigen testing (UAT). 2019-07-19 · The 2007 Infectious Diseases Society of America and American Thoracic Society (IDSA/ATS) guideline on community-acquired pneumonia (CAP) recommends urinary antigen testing (UAT) for Streptococcus pneumoniae (SP) and Legionella pneumophila (LP) in patients with certain clinical characteristics.

However, international guidelines are not unanimous regarding antibiotic reassessment in case of a positive UAT. In addition to sputum cultures, blood cultures (when indicated), and respiratory viral testing, urinary antigen testing for 2 specific etiologies – the pneumococcus ( Streptococcus pneumoniae) and Legionella pneumophilia serogroup I – are frequently performed. 2018-07-20 · BACKGROUND: The pneumococcal urinary antigen test (UAT) has been known to improve sensitivity and specificity for the diagnosis of pneumococcal pneumonia. Associations of UAT results with prognosis in community acquired pneumonia (CAP) are not known. Pneumococcal and Legionella urinary antigen tests are specific and moderately sensitive, but their utilityin low-resource settings is uncertain.
