Molecular diagnostics is an integral part of the in vitro diagnostics (IVD) industry and has gained an accelerated momentum in recent years. It represents more than one-tenth of the global IVD market with a growth trajectory secured through platform innovation in lower-cost nucleic acid amplification tests (NAATs) and clinical next-generation sequencing (NGS).
As healthcare becomes more dependent on molecular diagnostic testing, suppliers are continually developing new molecular methods. These include improvements in PCR (polymerase chain reaction), as well as newer amplification methodologies. The rapid improvement in workflow and turnaround time for most molecular tests has thus provided promising results. The newly developed assays are more accurate than before and have the potential to replace many conventional assays. Advancements in technology have also resulted in more user-friendly testing platforms that are automated, have lower risks for contamination, and have the ability to deliver faster results.
Microfluidics. The emergence of microfluidics and nanotechnologies has enabled both new capabilities and instrument sizes practical for point-of-care (POC). They have introduced new functionality, enhanced the sensitivity, and reduced the time and cost involved in conventional molecular diagnostic techniques. Overall, microfluidic approaches to a wide variety of molecular diagnostics applications are developing rapidly. Because of its advantages, microfluidics technology holds the promise for developing molecular diagnostic tests with improved sensitivities, accuracy, turnaround time, and affordability.
NGS. The principle of NGS has remained virtually the same since its introduction, but recent improvements and automation have dramatically increased the speed and accuracy in delivering maximum volume of data. NGS technologies have now far exceeded previous DNA sequencing technologies, both in the breadth of genomic real estate that can be sequenced in a single experiment and in the depth of coverage for each genomic region sequenced, which allows for a superior limit of detection for low-level sequence variants. Labs are moving many molecular assays over to NGS – especially those involving large numbers of variants, whether for a single gene or multiple genes. Pyrosequencing is currently the variant of choice within NGS systems.
NAATs. NAATs are now considered as the gold standard method for diagnostic practices such as screening donated blood for transfusion-transmitted viruses. With recent NAATs, the turnaround time is reduced to 1–2.5 hours, resulting in improved clinical outcomes and reduced hospital cost. Multiplexed NAATs have been designed to detect multiple viruses or subtypes in a single run. Their detection platforms can comprise up to 20 viruses using diversified panels, for example, concurrent detection of HAV, HBV, and HCV infections, as well as co-infections.
PCR. The most widely used variants of conventional amplification are real-time PCR (quantitative PCR) and reverse transcription-PCR (RT-PCR). Both are nowadays becoming benchmarks in assessing the viral load. Among the latest enhancements in PCR systems, extraction, amplification, and detection steps have been combined within one unit. Today, new advances in PCR technology, including more sensitive assays and high-throughput instruments, may further revolutionize healthcare. Digital PCR (dPCR) is an increasingly popular manifestation of PCR that offers a number of unique advantages and is a robust and reproducible approach that could lend itself to supporting accurate diagnostics in the future.
The current state of science is all about customized and evidence-based medicines and as such, the coming years will witness a transformation in the healthcare industry. The diagnostic business in India is all set to witness a movement toward molecular diagnostics. The molecular diagnostics products market is expanding rapidly as they possess higher precision and allow for speedy detection of infectious diseases and genetic disorders at an early stage of development.
