Infectious disease diagnostics is process of identifying the presence of foreign antigen/organism with the help of various diagnostic tools. Infectious disease conditions are highly prevalent in under developed regions due to lack of awareness for personal hygiene, minimal healthcare expenditures and absence of efficient physician services. The high incidence of infectious diseases across emerging economies formulate a major share in overall market. This has grab the attention of in vitro diagnostic device manufactures to invest into emerging economies. These companies are taking efforts to develop and commercialize cost effective tools for the infectious disease diagnosis. Presently, the gold standard tests available for bacterial infections and sexually transmitted disease diagnosis have major market share. However, these test are expected to replace by molecular techniques in future.
