COVID-19 pandemic positively impacted isothermal nucleic acid amplification technology (INAAT) market. Since INAAT offers simple operation, rapid detection, and accurate results. As a result, it becomes more ideal for primary testing centers in urban as well as rural areas. INAAT is in high demand since PCR-based nucleic acid detection technology is time-consuming and requires specialist equipment.

Moreover, it is difficult to work with PCR in primary-level medical institutions. Antibody-based detection has limitations because of the late appearance of antibodies, that makes early diagnosis of virus difficult, whereas antigen-based detection has low sensitivity, that often result a high false-negative rate.

Isothermal nucleic acid amplification technology (INAAT) methods allow for the rapid, exponential detection of a nucleic acid target sequence. This process is not limited by the constraint of thermal cycling. Isothermal amplification, when integrated into microsystems or portable devices, improves nucleic acid-based on-site diagnostics and increases sensitivity. In addition, using different enzymatic approaches to separate the two DNA strands prior to replication, INAAT can achieve amplification in 15-16 minutes.
