NAT involves three major processes: sample pooling and nucleic acid (NA) extraction, target NA amplification, and target amplicon NA detection. Polymerase chain reaction (PCR), strand displacement amplification (SDA), ligase chain reaction (LCR), transcription-mediated amplification (TMA), and nucleic acid sequence-based amplification are the most common NAT technologies (NASBA). The NAT market can be divided into five major segments based on its major applications: infectious diseases, genetic diseases, cancer, forensic testing, and paternity testing.
Because of the higher growth rate of diagnosis, treatment, and research activities, emerging countries in the Asia Pacific region, such as China and India, are hotspots for investment. Nucleic acid testing aids in the detection of nucleic acids such as viral DNAs or RNAs inpatient specimen samples. The technique is beneficial in providing special assistance to both doctors and patients. To deal with the increasing severity of health-related issues that the population is more prone to, the healthcare industry requires advanced techniques. Increasing chronic disease incidences as a result of changing lifestyles have resulted in an increase in demand for diagnostic procedures around the world.
