Paper-based NAAT for Ultra-sensitive Detection of Pathogens

Nucleic Acid Amplification Testing (NAAT) is the most accurate detection method for most of the infectious agents. It is increasingly becoming popular in lab medicine. In addition, advent of novel technologies, usability, and sample-to-result systems, NAAT finds applications in a wide range of new fields of testing. In the future, it is expected to play a significant role in making predictive & personalized medicine.

New Low-cost, Automated System for Disease Detection :-

A new innovation by an Asst. Professor at Purdue University could enable highly sensitive detection of various infectious diseases or viruses including HIV by using nucleic acid amplification testing on paper. This low cost, automated point-of-care (POC) test allows ultrasensitive detection of pathogens with nominal user interaction.

It also reduces the waiting time for results by eradicating the need for additional laboratory tests. The new technology allows amplification reagents to be printed on a paper and switched out for definite gene targets. This can enable the detection of different diseases and pathogens. The test can also check the antibiotic resistance of these pathogens.

Market Overview :-

According to a report made available by Radiant Insights, Inc.; the nucleic acid amplification testing market is anticipated to generate substantial revenue by 2022. Growing demand for sophisticated diagnostic measures along with the investments in R&D for advanced biotechnological diagnostic means are expected to drive the market during the forecast period (2012 to 2022).

In addition, high prevalence of various infectious diseases can further boost the overall market. Favorable initiative programs carried out by the government bodies to bring these tests in different screening programs can also positively affect the market till 2022.

Market Players :-

Some of the dominant market players are Bio-Rad Laboratories, Inc.; bioMérieux SA; Siemens Healthineers; Novartis AG.; and F. Hoffmann-La Roche Ltd. Most companies adopt market strategies such as novel product development and regional expansions to maintain their market position.
