Measles IgM ELISA Kit
INTENDED USE
Human measles IgM ELISA kit can be used for measuring in-vitro quantitative amounts of human IgM antibodies to measles virus (measles-IgM) present in serum and plasma samples. This assay has a minimum analytical sensitivity limit of 1.07 U/ml.
BACKGROUND
Measles which are sometimes referred to as rubeola, are an enveloped RNA virus, negative sense and single stranded that belong to the Paramyxoviridae family. An extremely contagious viral infection which is usually transmitted via respiratory secretions, it can infect the back of the throat and cells in the lungs. Some of the common symptoms of this disease include: dry cough, sore throat, a runny nose, a high fever, tiny white spots inside the mouth, red eyes and a characteristic rash which spreads from the face to the rest of the body. Measles virus is known to show more severe expression among undernourished or younger children, displaying a higher incidence of hemorrhage Measles (5-10% leading to lethal cases). Two of the most common methods which are used for detecting measles infection are: antibody testing (IgG and IgM) and viral islation detection (RT-PCR).
