Chlamydia Pneumoniae IgM ELISA Kit
INTENDED USE
Human Chlamydia pneumoniae IgM ELISA kit is a protocol designed for in-vitro quantitative measurement of human IgM class antibodies against Chlamydia pneumoniae (Chlamydia pneumoniae-IgM) present in plasma or serum. This assay has a minimum analytical sensitivity limit to a diagn. 83.3%.
BACKGROUND
Chlamydia pneumoniae has been implicated a large number of chronic illness for example asthma, multiple sclerosis, arthritis, atherosclerosis and many others. However, it has been found to be a common cause of both lower and upper respiratory illnesses such as pneumonia, pharyngitis, sinusitis and bronchitis in both adults and children. The diagnosis of acute infections is quite well established in most laboratories, however the diagnosis of the chronic infections pose many difficulties since the infections can be caused by a multitude of factors. Typically, diagnosis is usually based on either direct microscopy or serology (such as ELISA) methods. Atypical pneumonia, sinusitis and bronchitis are the most frequent respiratory diseases which are caused by C. pneumonia, persistent respiratory infections such as these are accepted as good indicators for any possible Chlamydia infections.
