Human Chikungunya virus IgG ELISA kit is a method for detecting in-vitro quantitative amounts of IgG class antibodies against Chikungunya virus (Chikungunya IgG) in human plasma or serum. This assay has a minimum analytical sensitivity limit to a diagn. >90%.
Chikungunya is a mosquito-borne viral disease that belongs to the alphavirus genus Togaviridae family. The virus can be transmitted from one human to another by the bites from an infected female mosquitoes. Some of the common symptoms are severe joint pain, muscle pain, fever, fatigue, rash and headache. Chikungunya disease is found to shares some clinical signs with are very similar to zika and dengue. At present it has been identified in over 60 countries that include Europe, America, Africa and Asia. There are several methods which have been used for its diagnosis, for example serological test like ELISA have been routinely used to confirm the presence of either IgG or IgM anti-chikungunya antibodies. Also, it have been identified that the levels of IgM antibody are at their highest between 3 to 5 weeks following the onset of illness and this can persist for up to 2 months.
