In clinical diagnostics, a crucial trend is Next-Generation Sequencing (NGS), revolutionizing by simultaneously sequencing millions of DNA or RNA molecules. This provides detailed genetic information for precise, personalized diagnosis and treatment. NGS monitors pathogen evolution, as seen with SARS-CoV-2, identifying new variants. Recent NGS trends focus on cost/time reduction, improved platform performance, and scalable solutions, along with developing bioinformatic tools for efficient data analysis in clinical laboratories.

NGS facilitates comprehensive analysis of immune cell populations and genetic variations associated with immune-related disorders. In molecular diagnostics, NGS enables rapid detection of genetic mutations and chromosomal abnormalities implicated in diseases like cancer and infectious diseases. Its high-throughput sequencing capabilities allow for personalized treatment strategies based on individual genetic profiles. NGS-based approaches, such as targeted gene panels and whole exome sequencing, enhance disease diagnosis and treatment decision-making. Overall, NGS advances immunological and molecular diagnostics by providing detailed genomic information critical for disease management.

NGS was especially influential in driving personalized medicine in Oncology during last decade. For many cancers NGS is now indicated and also recommended for coverage in the US. Challenge in the practice is alignment of NGS methodologies, incorporation of NGS testing as a part of standard of care prior to treatment decisions and appropriate timing for availability of relevant results as cancer patients urgently need care. As NGS use evolves not only within clinical drug development space but even more in practice resolving these aspects will be critical.

CRISPR, once confined to labs, is now making strides into in vivo editing i.e. altering genes within organisms. New Cas enzymes like Casɸ and Cas12a refine targeting, minimizing off-target edits. Base editing enables single-nucleotide changes sans DNA breaks, reducing risks. However, transporting CRISPR into specific cells remains tricky as viral vectors like AAVs have size and tissue limitations and Nanoparticles offer versatility but raise safety concerns. There is a lot of excitement as early trials target diseases like sickle cell anemia, correcting genes in patients' blood stem cells. Duchenne muscular dystrophy trials aim to restore dystrophin protein. CAR-T therapy edits immune cells to combat cancer.

Currently CRISPR technology has made significant inroads in the US. To truly reach its diagnostic and treatment-guiding potential technology needs to be adaptable for the global us. Also, proper guidances by medical societies and regulatory bodies need to be created and supportive.

My clients working in the field of infectious diseases tell me that CRISPR-based diagnostics can be employed to detect drug resistance mutations in pathogens. This information is critical for selecting appropriate treatment strategies and avoiding ineffective medications.

The versatility of aptamers allows for precise recognition of various analytes, offering advantages like stability and ease of synthesis. Integrating aptamers into these diagnostic technologies enhances their performance, contributing to the ongoing trends of miniaturization, increased sensitivity, and incorporation into smart and wearable devices. This adaptability positions aptamers as valuable tools in advancing the capabilities of immunoassays and biosensors for diverse diagnostic applications.

Immunoassays combined with biosensors have come a long way in meeting patient and provider needs especially for many diabetes patients. To truly drive more innovation it would be very useful to see pharmacoeconomic data that describes improvements in quality of life, management of disease, and avoidance of hospitalizations over time for patients using technology. This kind of research could also address comparison of different assays and biosensors to emphasize future development of well performing aspects and products.

In vitro assays, crucial in this landscape, enhance the sensitivity of liquid biopsy by allowing controlled analysis of genetic material and proteins outside the body. These assays excel in cancer diagnostics, detecting circulating tumor DNA with high precision for real-time monitoring. Beyond oncology, they contribute to infectious disease diagnostics, prenatal testing, and chronic condition monitoring. In developing companion diagnostics, they align treatments with individual molecular characteristics. Despite challenges, collaborative efforts are advancing the reliability of in vitro assays, promising earlier and more precise disease detection in a new era of personalized medicine.

Liquid biopsy is a non-invasive molecular diagnostic test analyzing circulating tumor DNA (ctDNA) or other biomarkers like circulating tumor cells (CTC) or exosomes in a patient's blood or other bodily fluids. This method provides valuable insights into the molecular profile, heterogeneity, and dynamics of a tumor, enabling early detection, prognosis, and treatment response monitoring in cancer. Liquid biopsy can also be employed for detecting minimal residual disease (MRD) and cancer recurrence post-treatment. Recent trends focus on enhancing isolation and detection of ctDNA and other biomarkers, increasing sequencing coverage and depth, and developing standardized and validated assays and protocols in liquid biopsy.

For some cancers liquid biopsies are highly preferred to tumor tissue biopsies in order to avoid great discomfort, pain and even increased mortality of patients. So it is critical that accuracy, reliability and standardization of tests using liquid biopsy happen in the future. Covering these aspects would enable liquid biopsy use as a standard in oncology practice to meet patient care needs.

I've been told that liquid biopsy offers several advantages over more traditional biopsies including non-invasiveness, early detection, real-time monitoring, and the ability to provide comprehensive genetic information for improved disease management across various medical conditions including rare diseases and neurology.

One of the techniques that, to some extent, incorporates the concepts of liquid biopsy, biosensors, and artificial intelligence is the use of FTIR (Fourier Transform Infrared Spectroscopy) to identify patterns of chemical groups for distinguishing between diseased and healthy individuals. With the use of artificial intelligence, this technique may be capable of recognizing patterns that can, at the very least, assist in triaging patients in situations like a pandemic, for example.
