Key Market Challenges

Lack of Standardization in Sample Collection and Analysis

One of the most critical barriers to market growth is the absence of standardized protocols for saliva collection, storage, and diagnostic analysis.

Saliva composition can fluctuate due to factors such as hydration levels, diet, and circadian rhythms, making it difficult to ensure consistent sample quality. While saliva diagnostics are non-invasive, improper preservation during transport can compromise the stability of biomarkers, particularly RNA and proteins, leading to inaccurate results. Unlike blood-based diagnostics, saliva testing lacks globally recognized procedures and quality control measures, creating discrepancies in diagnostic outcomes across different labs and regions.

The lack of standardization undermines the reliability and comparability of test results, eroding confidence among healthcare providers and patients. Without a unified framework, regulatory approvals and clinical adoption remain slow, restricting market penetration.

Limited Awareness and Adoption Among Healthcare Providers

Despite its advantages, saliva diagnostics face skepticism and underutilization in clinical practice, particularly in regions where traditional diagnostic methods dominate.

Many healthcare professionals still consider saliva-based diagnostics less reliable than established blood or tissue-based methods, especially for high-stakes applications like oncology and infectious disease detection. A lack of training programs and educational initiatives for clinicians and laboratory technicians hinders the proper integration of saliva diagnostics into routine practice. Established workflows in hospitals and diagnostic labs often prioritize traditional methods, resulting in resistance to adopting new saliva-based technologies.

The limited trust and adoption among medical professionals slow the commercialization of saliva-based tests, creating a bottleneck for market expansion despite technological advancements and patient demand.

Competitive Pressure from Established Diagnostic Modalities

The dominance of traditional diagnostic methods, particularly blood and tissue-based testing, poses significant competition for saliva diagnostics.

Blood and tissue-based tests have decades of clinical validation, extensive regulatory approvals, and widespread trust among medical professionals, making them the default choice for diagnostics. Conventional diagnostic methods offer a wider range of applications and biomarkers, often overshadowing the capabilities of saliva-based solutions. While saliva diagnostics can be cost-effective in some cases, established methods benefit from economies of scale, making them more competitive in terms of pricing and availability.

The entrenched presence of traditional diagnostic modalities limits the opportunities for saliva diagnostics to capture market share, especially in conservative healthcare systems where innovation adoption is slow.
