Improving disease management and therapy with MDx

Over the next seven years, the molecular diagnostics market is poised for a magnificent spike in CAGR in terms of revenue.

Molecular diagnostics has emerged as a viable and cost-effective alternative for infectious disease testing, particularly in resource-limited environments with diverse potential causes of infection. Their rapidity, complexity, and adaptability make them highly valuable, allowing healthcare systems to optimize resources and respond promptly to emerging risks.

While several diagnostic methods, such as antigen and antibody detection, morphological identification, smear microscopic examination, nucleic acid detection, and microbial culture, are widely used, they have inherent limitations. These include a restricted range of detectable pathogens, low sensitivity, and prolonged detection cycles, which pose challenges in identifying infections caused by rare or novel pathogens.

To overcome these limitations, ongoing advancements in genetic and genomic studies have facilitated the rapid and sensitive identification of infectious diseases, using nucleic acid detection-focused molecular diagnostic tools. Techniques, such as high-throughput sequencing, polymerase chain reaction, gene chip technology, and isothermal amplification reaction, are widely employed as primary diagnostic methods.

Molecular diagnostics is evolving at an incredible pace.

Molecular diagnostics has been largely influenced by the proliferation of infectious diseases, and chronic illnesses, including cancer and heart diseases. Automated systems for extraction, DNA/RNA amplification, their detection using labels have propelled the rapid development of molecular technology. This has led to an expansion of diagnostics using DNA or RNA analysis in clinical laboratories. Further, the discovery of additional biomarkers will aid in the accurate and timely diagnosis of a patient as well as the prediction of the patient’s response to therapy.

Techniques for testing genetic materials
Current technologies for analyzing genomic aberrations in clinical applications include real-time PCR (qPCR), fluorescence in situ hybridization (FISH), microarrays, and next-generation sequencing (NGS). These cutting-edge methods present a chance to deliver rapid diagnosis by achieving ultra-high sensitivity.

Real-time PCR is rapidly replacing traditional microbial detection methods as it not only detects infection but also the drug resistance status of the pathogen, which provides an immediate treatment plan with effective drugs, reduces the generation of drug-resistant pathogens, and facilitates the recovery of patients. Similarly, real-time PCR is also used for mutation detection (BCR-ABL1, PML-RARA, EGFR, KRAS, etc.) and for monitoring the drug response in cancer diagnosis and treatment.

In cancer prediction and early detection, specific germline mutations like BRCA1 and BRCA2, TP53, gene rearrangements, etc., can be detected using NGS. Cancer screening using NGS has contributed to decreasing the morbidity and mortality of cancer; therefore, molecular diagnostics not only detects but also categorizes the types of diseases, helps clinicians make more informed treatment choices, and also helps them predict the outcome of treatment.

What the future holds
Technological advancements have led to the creation of molecular POCT devices that are capable of on-site, real-time testing, allowing for rapid diagnosis and treatment choices. PCR-based testing outweighs all alternatives, as sequencing devices are more expensive, other technologies aimed at examining genome complexity without PCR are expected to gain traction in the coming years. The notion of traditional wet lab will evolve to lab-on-a-chip with the advent of integrated silicon chips loaded with biomolecules, that can analyze hundreds of genes/proteins in hours.

These molecular diagnostics have become essential for the early diagnosis of infectious diseases, allowing for the detection of multiple pathogens, analysis of drug-resistant genes, and pathogen homology assessments.

Molecular diagnostics in infectious diseases encompass testing the host’s susceptibility to disease, screening for infections, diagnosing key infections, and tracking disease progression and pathogen spread. These tests are highly sensitive and specialized, reducing the need for unnecessary diagnostic procedures, medications, and hospital-acquired infections. Molecular testing improves patient care and offers potential financial benefits by optimizing resource utilization and reducing healthcare costs.

Overcoming challenges and embracing advancements in molecular diagnostics will continue to be instrumental in the effective management and prevention of future outbreaks. By leveraging the power of molecular technologies, healthcare systems can proactively protect communities, optimize resource allocation, and ultimately preserve and improve global public health.
