Abstract: Abtract:This paper has analyzed the stauts of the research on countris and overseas’ s loop-mediated isothermal amplification through the quantity of docunents,document’s contents and the places where these authors are distributed ,And it discloses the characteristics of research on the loop-medidated isothermal amplification among the genemo testing techologies reasearch and predicts the loop-medidated isothermal amplification research tendency and the developing direction . It has provided reference basis for scientific research on loop-mediated isothermal amlification and information communication .
