Respiratory viruses

Product catalog summary

Introduction
Adenoviruses are pathogens affecting humans and animals, spreading via droplets or the fecal-oral route, with an incubation period of 5-7 days. They primarily affect the respiratory and digestive tracts, causing conditions like pharyngitis and pneumonia. Influenza, a common winter epidemic, spreads through droplets and affects the respiratory system. It has three types: A, B, and C, with A and B being more clinically significant. Parainfluenza viruses, affecting mainly children and immunocompromised individuals, spread via air and droplets, causing respiratory illnesses. Respiratory syncytial virus (RSV) primarily affects children, with reinfections possible in adults.

Diagnosis of Infection
Diagnosis involves clinical evaluation, epidemiological history, and laboratory tests. Immunoenzymatic tests like ELISA are crucial for detecting antibodies, with IgM, IgA, and IgG responses varying in presence and duration.

ELISA Test Principle
The ELISA tests use a sandwich method, involving steps like sample dilution, incubation, washing, and color intensity reading at 450 nm. The tests detect antibodies against adenovirus, influenza A and B, parainfluenza, and RSV.

Clinical Application and User Comfort
The kits are used for screening viral respiratory infections, offering ready-to-use, color-coded components, and semiquantitative result evaluation. They provide high diagnostic specificity and sensitivity.

Test Characteristics
ELISA tests show varying sensitivity and specificity across different viruses and antibody classes, with adenovirus IgA showing 96.0% sensitivity and 94.9% specificity, and RSV IgG showing 97.5% sensitivity and 87.6% specificity.

Ordering Information
The document lists various ELISA and SmartEIA kits for different viruses and antibody classes, each with 96 wells, designed for automated processing using the Agility® analyser.

Company Information
TestLine Clinical Diagnostics Ltd. is certified to ISO 9001 and ISO 13485 standards for in vitro diagnostics.

INFECTIOUS SEROLOGY – VIROLOGY – VIRAL RESPIRATORY INFECTIONS Introduction Adenoviruses are human and animal pathogens Human parainfluenza viruses (HPIV) belong to a sub- characterised by significant indifference to the envi- group of paramyxoviruses (the Respirovirus and Rubu- ronment. Acute adenoviral infections have an incuba- lavirus genera) and cause infections primarily in young tion period of 5–7 days. They spread via droplets or the children, adolescents and immunodeficient individuals, faecal-oral route. Reinfections are common. The pre- but may affect everyone. The parainfluenza virus...

G and fusion glycoprotein F) lead to the production of virus-neutralizing antibodies. G glycoproteins are highly variable, in contrast to F glycoproteins. Diagnosis of Infection Diagnosis of the disease is based on the overall clinical picture, epidemiological anamnesis and laboratory tests. Acute respiratory infections can be detected by isolation of the virus or serologically. Immunoenzymatic tests are important for the serological diagnostics because they are very sensitive and allow the detection of various antibodies classes. Responses of IgM-class antibody may sometimes be missing, whereas...
