Dengue Secondary Infection
Secondary infection is more dangerous than Primary infection. Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) have been observed to occur frequently with secondary dengue infection.
Secondary infection can be detected by testing the patient’s IgG. NS1, IgG, and IgM are all high during the first day of infection; hence, possibly interpreted as a primary infection, but NS1 and IgM will go down from the second day onwards, and IgG will remain high. Because of this, the interpretation would be positive for secondary infection.
Since SD Dengue Duo is a combo test for Antigen and Antibody, it can be used to test for secondary infection of dengue. If the IgG remains positive from the first day onwards, the interpretation would be positive for secondary infection; hence, giving you more reasons to use SD Dengue Duo.
