The market is being driven by the rising prevalence of chronic and infectious diseases, prompting a growing demand for accurate, early detection and routine health monitoring.

This is especially critical in aging populations and in managing conditions like diabetes, cardiovascular diseases, and respiratory infections. Technological innovations such as molecular diagnostics, point-of-care testing, and automation are further fueling market growth by delivering faster, more precise results. A key trend shaping the industry is the integration of digital tools and AI, enabling early disease prediction, real-time data analysis, and enhanced diagnostic accuracy. Concurrently, the decentralization of healthcare, through at-home kits, wearable biosensors, and telehealth, is reshaping patient care delivery.

The market also presents significant opportunities with the rise of personalized medicine and genomics, as demand grows for biomarker-driven diagnostics and companion testing in oncology and rare diseases. However, high testing costs, regulatory delays, and limited access in low-income regions pose major challenges. The need for trained personnel and secure handling of digital data further constrains widespread adoption. Despite these hurdles, the market is poised for robust growth, supported by increasing healthcare investments, improved infrastructure, and a shift toward preventive and precision care worldwide.

Facts & Figures

• Rising Prevalence of Chronic and Infectious Diseases: Increasing global cases of diabetes, cardiovascular diseases, cancer, and infectious diseases like COVID-19 continue to drive demand for timely and accurate diagnostic testing. For instance, according to the WHO (2024), non-communicable diseases account for nearly 74% of global deaths, reinforcing the urgent need for routine diagnostics in both developed and developing countries.
• Technological Advancements in Diagnostic Tools: Innovations in molecular diagnostics, next-generation sequencing (NGS), and AI-based image analysis are making diagnostics more precise, faster, and accessible. For instance, in June 2025, QuidelOrtho acquired LEX Diagnostics, integrating ultra-fast molecular platforms for rapid COVID and flu testing, highlighting the push toward rapid, high-tech solutions.
• Growth in Point-of-Care and At-Home Testing: The demand for decentralized, real-time diagnostic testing is increasing, particularly in remote and home care settings, thereby improving access and compliance. Like, RDI’s acquisition of Inicio Health (April 2025) focused on AI-enabled self-sampling kits, exemplifying the market’s pivot toward convenient, home-based diagnostics.
• Rising Geriatric Population and Preventive Healthcare Awareness: Aging populations are more vulnerable to chronic conditions, increasing demand for routine lab testing and preventive screening. UN data shows the global population aged 65+ will reach over 1.5 billion by 2050, directly correlating to increased diagnostics volume across cardiovascular, oncology, and metabolic panels.

• In March 2025, Australia’s leading pathology firms, Healius and ACL, resumed negotiations for a ~A$?2?billion merger, aiming to consolidate pathology services and achieve ~A$?95million in cost synergies.
• In March 2025, India’s Metropolis strengthened its North India presence through the acquisition of Scientific Pathology in Agra, expanding collection centers and patient outreach.
• In November 2024, Australia’s Sonic agreed to acquire Germany’s LADR group (€423million), gaining ~2,800 staff and enhancing European lab capacity and logistics.

Clinical Diagnostics Market Segmentation:

Based on the product type:

• Instrument
  • Blood Gas Analysers
  • Haematology Analysers
  • Clinical Chemistry Analysers
  • Immunoassay Analysers
  • Urine Analysers
  • Coagulation Analysers
  • Others
• Reagents
  • Taq Polymerase
  • MMLV RT
  • HIV RT
  • Hot Start Taq Polymerase
  • UNG
  • RNAse Inhibitors
  • BST Polymerase
  • PCR Master Mix
• Software and services
  • Laboratory Information Management Systems
  • Diagnostic Imaging Software
  • Data Analysis Software
• Kits and assays

Instruments lead the market with the highest market share. Instruments in clinical diagnostics refer to the specialized machinery and devices used to carry out various tests. These range from simple equipment like centrifuges, which separate different components of blood, to more complex machines like polymerase chain reaction (PCR) devices, which are used for DNA testing. Other instruments can include haematology analysers for blood cell counts, biochemistry analysers for measuring chemical substances in the blood, and imaging devices like X-rays or MRIs. These instruments are designed to be highly accurate and efficient, allowing for quick and reliable diagnoses. In contrast, the software and services segment holds the smallest market share, as it is a support function that complements rather than drives core diagnostic operations directly.

Based on the test:

• Lipid Panel
• Liver Panel
• Renal Panel
• Complete Blood Count
• Electrolyte Testing
• Other

Among the various test types, lipid panels stand as the largest segment. A lipid panel is a blood test that measures different types of fats and cholesterol levels in the blood, notably low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. The test provides valuable information about the risk for heart disease of an individual and helps guide decisions about what treatment can be best if there is borderline or high risk. The renal panel, also commonly known as a kidney panel, consists of various tests aimed at assessing kidney function. The test is critical for diagnosing kidney diseases and for monitoring individuals who are at risk for kidney complications due to conditions like diabetes or high blood pressure, but currently it holds relatively low market share.

Based on the application:

• Infectious Diseases
• Oncology 
• Cardiology
• Endocrinology
• Nephrology
• Autoimmune Diseases
• Hematology
• Toxicology
• Neurology
• Others

Among the application segments, infectious diseases hold the largest market share in the market. This dominance is fueled by the global prevalence of viral and bacterial infections, increasing demand for early detection, and the necessity for continuous disease surveillance. Events like the COVID-19 pandemic, along with persistent diseases such as HIV, hepatitis, and tuberculosis, have significantly increased diagnostic volumes. Enhanced global focus on public health and the expansion of rapid and point-of-care testing have also contributed to growth. Toxicology, on the other hand, accounts for a smaller market share, as it caters to niche applications like drug testing and exposure analysis, with limited routine usage compared to broader disease categories.

Based on the end user:

• Hospital
• Laboratory Diagnostic
• Laboratory Point-of-care Testing
• Other

Based on end-user segmentation, hospitals hold the largest market share in the market. Hospitals are the primary healthcare access points for diagnosis and treatment, offering comprehensive diagnostic services across departments like emergency care, oncology, and internal medicine. Their ability to perform a wide range of complex tests in-house using advanced instruments and trained personnel contributes significantly to their dominance. Additionally, government and private hospital investments in lab automation, integrated electronic health records, and molecular diagnostics further boost their share. On the other hand, laboratory point-of-care testing, while growing rapidly due to its convenience and speed, still accounts for the smallest market share due to limited testing capabilities and dependency on basic diagnostics.
