2. Point-of-Care Testing Is Expanding
Point-of-care testing (POCT) brings diagnostic testing closer to the patient.
Instead of relying exclusively on centralized laboratories, healthcare providers can use portable or compact diagnostic systems in hospitals, clinics, pharmacies, emergency departments, and other care settings.
Examples include testing for:
- Blood glucose
- Infectious diseases
- Cardiac biomarkers
- Pregnancy
- Coagulation
- Respiratory infections
- Cholesterol
- Other biochemical and molecular parameters
The growth of POCT is driven by the need for faster results and improved access to diagnostic services.
At-home testing is also expanding the role of decentralized diagnostics. However, manufacturers must ensure that products intended for self-testing are designed and validated for the intended user, environment, and level of user interaction.
3. Molecular Diagnostics and Multiplex Testing
Molecular diagnostics continue to transform disease detection by identifying genetic material, biomarkers, and other molecular characteristics.
Technologies such as:
- Polymerase Chain Reaction (PCR)
- Real-time PCR
- Next-Generation Sequencing (NGS)
- Isothermal amplification
- Multiplex molecular testing
are being used across infectious disease, oncology, genetic testing, and other applications.
Multiplex testing is particularly valuable because a single test can detect multiple targets or biomarkers. This can help reduce testing time and support more comprehensive diagnostic assessment.
As molecular diagnostic technologies become more sophisticated, manufacturers need to establish appropriate analytical performance, clinical performance, quality controls, and regulatory evidence.
4. Companion Diagnostics and Personalized Medicine
Companion diagnostics are closely connected with the growth of personalized medicine.
A companion diagnostic can help identify patients who are more likely to benefit from a particular therapeutic product or who may be at increased risk of an adverse reaction.
This creates an important connection between:
Diagnostic technology + biomarker detection + therapeutic decision-making
Companion diagnostics are particularly relevant in areas such as oncology, where molecular and genetic information can influence treatment decisions.
Manufacturers developing companion diagnostic products must carefully consider the intended use, clinical evidence, analytical performance, regulatory pathway, and relationship between the diagnostic and associated therapy.
5. Digital Pathology
Digital pathology is changing the way pathology information is captured, stored, analyzed, and shared.
Instead of relying exclusively on conventional microscope-based workflows, tissue slides can be digitized and reviewed using digital platforms.
Digital pathology can support:
- Remote consultation
- Image sharing
- Workflow management
- Archiving
- Quantitative image analysis
- AI-assisted pathology
- Research
The combination of digital pathology and AI has the potential to improve laboratory workflows and support more consistent analysis.
However, manufacturers must consider software validation, image quality, interoperability, cybersecurity, clinical performance, and regulatory requirements when developing digital pathology solutions.
6. Non-Invasive and Minimally Invasive Diagnostics
Another important direction in the diagnostics sector is the development of technologies that reduce the need for invasive sample collection.
Examples include:
- Breath-based diagnostics
- Skin sensors
- Optical sensing
- Saliva-based testing
- Sweat analysis
- Non-invasive imaging
- Wearable biosensors
These technologies can improve patient comfort and may make frequent or continuous monitoring more practical.
For manufacturers, however, developing a non-invasive diagnostic involves demonstrating that the technology can produce sufficiently reliable and clinically meaningful results for its intended purpose.

7. Wearable and Continuous Diagnostic Technologies
Wearable technologies are increasingly being used to collect health and physiological information outside traditional healthcare environments.
Depending on the device, wearable systems may monitor parameters such as:
- Heart rate
- Oxygen saturation
- Temperature
- Glucose
- Activity
- Sleep-related parameters
- Other physiological measurements
Connected diagnostic and monitoring devices can provide continuous data rather than relying on occasional measurements.
This creates opportunities for early detection and remote monitoring, but also introduces requirements around data integrity, cybersecurity, connectivity, software, usability, and patient privacy.

- Infection control
- Patient triage
- Public health surveillance
- Outbreak response
- Decentralized testing
Molecular, antigen-based, and other rapid diagnostic technologies continue to evolve, with manufacturers focusing on improving sensitivity, specificity, speed, ease of use, and scalability.
9. At-Home Testing and Self-Testing
The diagnostics sector is also moving closer to the consumer.
At-home and self-testing products can give individuals access to diagnostic information without requiring every test to be performed in a traditional laboratory or hospital.
This trend is particularly relevant for:
- Pregnancy testing
- Glucose monitoring
- Infectious disease testing
- Hormone testing
- Sexual health testing
