Nucleic acid detection system

The present application discloses a system for detecting target nucleic acid comprising: a container comprising a nucleic acid amplification mix comprising a primer labeled with different haptens at its 5' and 3' ends, and optionally dNTP labeled with a hapten to form a nucleic acid complex; and a lateral flow test device comprising a reservoir area comprising reagent conditions suitable for binding of a specific binding partner with the nucleic acid complex; a dye area comprising a specific binding partner to the nucleic acid complex, wherein the specific binding partner is linked or conjugated to a reporter dye or another hapten; and a test area comprising a different specific binding partner specific to a different aspect of the nucleic acid complex.
