Infectious Disease Diagnostics: Clinical Trials with Diagnostics CROs

In the world of medical research, the surge of novel diagnostics for infectious diseases has brought about significant advancements in healthcare. These new diagnostic methods are being rigorously tested in clinical trials to validate their efficacy and reliability. Many of these diagnostics are based on lateral flow immunoassay (LFIA), which detects specific antigens and antibodies. There is a growing trend towards at-home testing using saliva and mucous samples, making diagnosis more convenient for patients. Moreover, blood-based tests for infectious diseases like Lyme disease and other typically hard-to-detect infections are also under investigation.

In this article, we delve into the basics of new infectious disease diagnostics, discuss various approaches, and highlight the role of clinical trials in validating these new tests. We will also explore how clinical trials, conducted by diagnostics clinical research organizations (CROs), are being used to confirm the effectiveness of these new tests, leading to more rapid and convenient diagnosis and treatment of these diseases.

The Age of New Diagnostics for Infectious Diseases

With the advent of globalization, infectious diseases can easily spread across borders, making early detection and diagnosis a critical part of healthcare. Infectious diseases are a leading cause of death globally, and early identification can often lead to effective treatment. However, many infections are never diagnosed, leading to curable diseases becoming life-threatening.

The recent COVID-19 pandemic underscored the world's vulnerability to new and emerging disease-causing viruses, for which there are no tests or treatments. In a matter of weeks, nearly every country reported infections and deaths, healthcare systems became overwhelmed, and economies plummeted. This scenario is just one example of the complexities of infectious diseases that people across the globe face daily.

Approaches to Infectious Disease Diagnostics

Diagnostic tools for infectious diseases have become indispensable, providing prognoses, determining the best treatment options, and predicting treatment responses. To manage the wide variety and variability of infectious diseases, comprehensive testing strategies and access to innovative diagnostic tools are essential.

Traditionally, testing is performed in a central laboratory. Advancements in automation, test design, and analytics have allowed more samples to be processed in less time. However, for some infections, time is of the essence. Point-of-care tests, which are performed close to the patient, such as in an emergency care setting, can shorten the time needed to generate results. This allows for earlier identification of infection, initiation of appropriate treatment, and limiting unnecessary use of antibiotics.

The development of new diagnostics for infectious diseases involves various approaches. One such approach is the lateral-flow immunochromatographic tests that detect antigens from or antibodies to certain pathogens. These tests are simple, fast, and can be performed at the point-of-care without the need for specialized equipment or trained personnel. Another approach is the use of molecular diagnostics, such as polymerase chain reaction (PCR) testing, which detects the presence of the infectious agent’s unique genetic material (DNA or RNA). Molecular diagnostics offer high sensitivity and specificity, making them a preferred choice for accurate and rapid infectious disease diagnosis.

The Role of Clinical Trials in Diagnostics

Clinical trials play a crucial role in the validation of new diagnostics for infectious diseases. They provide a systematic way to test the effectiveness and safety of new diagnostic tests and procedures before they are approved for public use. Clinical trials are critical in determining whether a new diagnostic test is better than the current standard of care.

In the context of infectious disease diagnostics, clinical trials are conducted to evaluate various aspects of the diagnostic test, such as:

  • Sensitivity: The ability of the test to correctly identify those with the disease
  • Specificity: The ability of the test to correctly identify those without the disease
  • Accuracy: The overall ability of the test to correctly classify those with and without the disease
  • Feasibility: The practicality of implementing the test in real-world settings

Clinical trials for diagnostic tests are typically conducted in several phases. The initial phases involve a small group of participants to evaluate the safety, dosage, and side effects of the diagnostic test. If the initial phases are successful, the trial proceeds to the next phases, involving a larger group of participants to further evaluate its safety and effectiveness.

The Role of Diagnostics CROs in Clinical Trials

Diagnostics CROs, or Clinical Research Organizations, play a crucial role in conducting clinical trials for diagnostic tests. They provide specialized expertise and resources to facilitate the design, implementation, and analysis of clinical trials. Diagnostics CROs collaborate with biotech companies, pharmaceutical companies, and academic institutions to conduct clinical trials in a timely and cost-effective manner.

Diagnostics CROs provide a range of services, including:

  • Study design and protocol development
  • Regulatory submission and compliance
  • Patient recruitment and retention
  • Data management and statistical analysis
  • Quality assurance and auditing

By leveraging the expertise and resources of diagnostics CROs, researchers can accelerate the clinical trial process, ensuring that new and effective diagnostic tests reach the market as quickly as possible.

The Future of Diagnostics in Infectious Diseases

The field of diagnostics in infectious diseases is evolving rapidly. With advancements in technology and a better understanding of disease mechanisms, new diagnostic tests are being developed that are more accurate, faster, and easier to use. Moreover, the trend towards point-of-care and at-home testing is expected to continue, making diagnosis more convenient for patients and healthcare providers.

Furthermore, the demand for diagnostics for emerging infectious diseases, like COVID-19, is likely to increase. In response, diagnostics CROs are expected to play an even more significant role in accelerating the development and validation of new diagnostics through clinical trials.


In conclusion, the future of diagnostics in infectious diseases looks promising. With advancements in technology, the development of new diagnostic tests, and the pivotal role of diagnostics CROs in clinical trials, we can look forward to more rapid and convenient diagnosis and treatment of infectious diseases. As we continue to face the challenges of infectious diseases, the importance of clinical trials for diagnostic tests and the role of diagnostics CROs cannot be overstated.
