The diagnostic landscape in India has profoundly transformed over two decades. It evolved from basic walk-in laboratories to a sophisticated digital ecosystem, now including home testing and mobile reporting. Experts suggest we are entering a new frontier, where Predictive Genomics, next-generation sequencing (NGS), and precision medicine will redefine wellness and healthcare for everyone.

Industry leaders recently discussed this significant evolution at the 5th Healthcare Leaders Summit. Dr. Om Manchanda, Dr. Harsh Mahajan, Dr. Arjun Dang, and Dr. Sakthivel Murugan shared insights, moderated by Vikas Dandekar. The panel explored the role of genomics, diagnostics, and precision medicine in future wellness.

The Digital Transformation of Diagnostics

Dr. Manchanda emphasized how patient behavior and technology have reshaped diagnostics. Formerly, 80-90 percent of business came from walk-in lab visits. Today, however, digital platforms enable patients to book tests, provide samples at home, and access reports via mobile, eliminating the need to visit a lab physically. This shift highlights a major change in convenience and accessibility for patients across India.

From Preventive to Predictive Healthcare

A more profound shift involves healthcare philosophy, moving from prescriptive to preventive and now to predictive. Patient awareness has surged due to events like sudden cardiac deaths and the COVID-19 pandemic, which exposed comorbidity risks. Consequently, people now seek information about their genetic predispositions and risk factors. Science has advanced significantly, offering answers to these complex questions.

Dr. Manchanda believes predictive profiling will drive the next phase of diagnostics growth. These tests detect diseases early and flag underlying risks, empowering individuals to take proactive steps well before symptoms manifest. Therefore, early detection capabilities are expanding rapidly.

Integrated Diagnostics: Converging Technologies

Integrated diagnostics represents another crucial frontier. Dr. Mahajan explained how diagnostic silos are breaking down. Six years ago, his radiology center introduced next-gen sequencing. This was unusual, even globally, to combine genomics with imaging. Nevertheless, the concept was simple: patients and physicians desire a single, clear diagnosis, not fragmented data.

This vision led to the establishment of a caring center for advanced research in imaging, neurosciences, and genomics as early as 2016. The convergence of radiology, genomics, and research is not merely futuristic; it is actively happening now. Integrated diagnostics ensures that predictive insights from genomics complement imaging precision, particularly in areas like cancer, neurology, cardiology, and diabetes. This holistic approach significantly improves diagnostic accuracy and patient care.

Precision Medicine’s Expanding Horizon

Both experts underscore that the diagnostic sector is entering a phase where precision medicine and wellness truly intersect. Genomic profiling now guides more than just cancer therapy; it is entering mainstream areas such as cardiology, metabolic disorders, and preventive wellness. This expanded application ensures more targeted interventions.

The implications for individuals are substantial: tailored healthcare strategies, including lifestyle interventions, regular screenings, or targeted therapies. For the healthcare system, this promises enhanced efficiency, fewer misdiagnoses, improved treatment outcomes, and a greater emphasis on maintaining health rather than treating illness. India, with its growing patient awareness and vast population, is well-positioned to adopt these advancements.

Challenges and the Path Forward for Predictive Genomics

Despite promising advancements, challenges persist. Cost, accessibility, and awareness beyond urban centers will determine how quickly predictive and precision diagnostics become everyday healthcare. For example, while preventive health checkups are routine at the top end, predictive diagnostics represent the natural next step. Pioneers like Dr. Mahajan demonstrate how genomics and imaging can converge, making integrated, personalized healthcare a more tangible reality.

The convergence of genomics and imaging, particularly in areas like cardiology, neurology, and diabetes, is revolutionizing patient care. Understanding these complex interactions is key to unlocking the full potential of genomic medicine and health.

Breaking the "One-Size-Fits-All" Mold

The traditional model of wellness check-ups, often offered as silver, gold, or platinum packages, is increasingly outdated. This is especially true in an era demanding personalization. Dr. Dang highlighted that many people still choose tests based on family history and budget, a "cookie-cutter" approach that risks missing critical insights. He metaphorically stated, "It’s like painting with a broad brush when what we need is a fine stroke." Consequently, a more nuanced approach is essential.

To address this gap, his team developed Discover by Dr. Dangs, a free digital tool. This tool curates personalized test packages based on individual health goals, ranging from longevity and chronic disease management to fitness, mood, or sleep. It is also backed by evidence-based, peer-reviewed research. So far, over 7,000 personalized check-ups have been curated. Even among 30–35-year-olds, the overlap was only 20 percent, signifying that the majority required customized test combinations.

Dr. Mahajan further emphasized the limits of bundled packages, stating that "Someone at 30, 50, and 70 years opting for the same platinum package makes little sense. Many times, people are told they are fine and then succumb to a heart attack days later. Personalized diagnostics is not optional—it’s critical."

Genomics: The Engine of Personalization and Predictive Power

If personalization defines the future direction, genomics certainly serves as the engine driving it. Dr. Murugan reflected on MedGenome’s journey, noting a shift from diagnostics focused on identifying mutations and assessing risks for siblings or future generations, including prenatal checks, to a stronger emphasis on predictive power. Predictive genomics plays a crucial role in oncology, where genomic profiling determines eligibility for specific therapies. "Every drug has its own mutation marker. Predictive testing ensures the right drug reaches the right patient," he explained. Moreover, MedGenome now provides polygenic risk scores for 8–10 disorders, such as Parkinson’s and coronary artery disease, with over 90 percent predictive accuracy when combined with phenotypic data.

Overcoming Hurdles and The Future Landscape

Challenges for widespread adoption include cost, which remains significant even if India’s charges are a quarter of global costs. Data privacy is also critical. MedGenome, for instance, follows strict GDPR norms, keeps genomic data within India, and releases it only with patient consent. The data belongs solely to the patient. Furthermore, genomics addresses antimicrobial resistance (AMR), a "silent pandemic." Dr. Dang introduced bacteriophage sensitivity testing, which uses viruses instead of antibiotics to target specific bacteria.

Dr. Mahajan concisely summarized the future: "Precision medicine will grow rapidly because it saves lives. Predictive medicine will take longer, because human nature resists knowing risks early. But genomics is no longer the future—it’s already here." Experts concur that while genomics and precision diagnostics may be today’s "wellness craze," backed by science, personalization, and accessibility, they are undoubtedly tomorrow’s standard of care.
