Rapid test for the qualitative detection of Legionella pneumophila
antigen in urine samples. For professional in vitro diagnostic use only.
The Legionella pneumophila Rapid Test Cassette (Urine) is an
immunochromatographic in vitro diagnostic test. It is designed to detect
the soluble Legionella pneumophila serogroup 1 antigen in human urine
samples. Legionellosis is severe pneumonia caused by bacteria of the
genus Legionella assigned to the Legionellaceae family. This family now
includes 48 species and over 60 serogroups. About 20 species are
implicated in human diseases. The vast majority of Legionella infections
are caused by Legionella pneumophila. Legionnaires’ disease is the main
clinical manifestation of Legionella infection, although extra
pulmonary infections and non-pulmonary diseases such as Pontiac fever do
occur. The name Legionella pneumophila is derived from the dramatic
epidemiological outbreak following the 1976 American Legion Convention
in Philadelphia. Legionella pneumophila is responsible for approximately
90% of infections and of these over 80% is due to a single serogroup,
serogroup. Legionella is a Gram-negative bacterium with the shape of
small rods which has polar flagella. Legionella bacteria have a
widespread proliferation in both natural and artificial aquatic
habitats. They are readily available in fresh water, cooling towers and
drinking water systems. Organisms can survive in a wide range of
conditions and temperature is a determining factor for the proliferation
of Legionella. Nosocomial infection is particularly associated with
legionella colonization of the hospital hot water system. The incubation
period of Legionnaires’ disease after being exposed to the bacterium
ranges from two to ten days. Most hospitalized patients develop high
fever often above 39.5 ° C (103 ° F). Coughing can be the first sign of a
lung infection. Other common symptoms include headaches, body aches,
chest pain, and difficulty breathing. Gastrointestinal symptoms are
common. Legionnaires’ disease (LD) is not contagious. The disease is
airborne and there is no evidence of direct person-to-person
transmission. People at risk are those whose immune systems are
compromised, including transplant recipients, the elderly, cigarette
smokers, or those with chronic obstructive pulmonary disease or chronic
kidney disease. Diagnosis of legionellosis can be difficult because the
signs and symptoms are nonspecific and do not distinguish L. pneumophila
infections from other common causes of pneumonia. L. pneumophila
infections are considered to be quite common but are likely
underdiagnosed and underestimated. The underdiagnosis of legionellosis
can in part be attributed to the need for rapid, specific and sensitive
diagnostic tests. The Legionella pneumophila Rapid Test Cassette (Urine)
detects soluble L. pneumophila serogroup 1 antigen in the urine. This
is a ready-to-use membrane test based on colloidal gold particles. This
test allows the detection of Legionella pneumophila LPS in urine
samples. The sensitivity and specificity of the test come from
monoclonal and polyclonal antibodies to Legionella. Mouse
anti-Legionella antibodies are conjugated with colloidal gold particles
and dried on a conjugated absorbent pad. Each strip is sensitized with
goat anti-Legionella antibodies in the line region (T) and with a
control antibody in the line region (C) as the urine sample migrates,
the conjugate is rehydrated and migrates along with the sample. If L.
pneumophila urinary antigens are present in the sample, a bond is formed
between the anti-L. pneumophila conjugates and L. pneumophila antigens
that will be captured by the specific anti-L reagent. pneumophila coated
on the stick. The results appear in 15 minutes in the form of a red
line that develops on the strip.
