Saliva Collection And Diagnostics Market Size, Share & Trends Analysis Report By Site Of Collection (Parotid Gland Collection, Submandibular/Sublingual Gland Collection), By Application, By End-use, By Region, And Segment Forecasts, 2025 - 2030

Market Size & Trends

The global saliva collection and diagnostics market size was estimated at USD 818.9 million in 2024 and is projected to grow at a CAGR of 4.7% from 2025 to 2030. Primary growth is driven by factors such as the rising demand for quick diagnoses of chronic diseases, advances in infant sample collection technology, and rising public awareness regarding safe and convenient diagnostic options for various conditions. For instance, in September 2021, Thermo Fisher Scientific, Inc. introduced the SpeciMAX Stabilized Saliva Collection Kit, designed for secure sample collection in research applications. This kit includes a spill-resistant funnel, a standardized tube, and a secure cap to facilitate proper sample handling.

The COVID-19 pandemic has positively influenced the demand for collection, driven by the rise in infectious disease cases, new product developments, and an increasing preference for non-invasive, self-administered tests. Saliva has emerged as a viable alternative sample for COVID-19 diagnosis, largely due to its ease of collection. Patients widely accept saliva testing since it does not require personal protective equipment (PPE) or healthcare personnel, allowing individuals to self-collect samples. The heightened need for COVID-19 diagnostics has opened substantial growth opportunities in this sector. For instance, in February 2022, researchers from the IrsiCaixa AIDS Research Institute and ICFO-The Institute of Photonic Sciences introduced a cost-effective, portable device that uses fluid and light manipulation to detect SARS-CoV-2 in oral samples.

Saliva-based tests offer a precise and painless alternative for assessing female hormone levels, standing out as a reliable diagnostic method. Previously, blood tests were the standard for measuring these levels, but they are costly, invasive, and often challenging to administer. Consequently, there has been a noticeable shift toward more affordable and convenient sample types like salivary collection. Saliva-based diagnostics are now applied to monitor various physiological conditions, including stress, depression, and sleep disorders, and are widely used in fields like occupational health and sports medicine, fueling market growth.

Innovations in non-invasive testing technologies are transforming the landscape, offering more comfortable and user-friendly alternatives to traditional diagnostic methods. New devices and kits are being introduced that enhance the accuracy and reliability of tests, making them more appealing to both healthcare providers and patients. These developments include improved collection techniques that ensure sample integrity and stability, which is essential for accurate results. Furthermore, the emergence of multiplex testing capabilities allows for the simultaneous detection of multiple conditions from a single sample, streamlining the diagnostic process and increasing efficiency.

With the development of more assays, oral collection is positioned to become a leading alternative for detecting and diagnosing a range of conditions, from cancers to monitoring disease recurrence, treatment effectiveness, and patient risk. For example, in November 2021, Salignostics introduced SaliStick, a pregnancy test that provides results using only an oral sample.

Site of Collection Insights

Based on site of collection, the submandibular/sublingual gland collection segment led the market with the largest revenue share of 49.2% in 2024. Around 70% of unstimulated saliva is generated by the submandibular gland, which is also the most affected by sialoliths, or salivary stonesa prevalent condition in middle-aged adults. Approximately 80% of these stones form in the submandibular gland, with 6-15% occurring in the parotid gland and 2% in the minor or sublingual glands. As cases of sialolithiasis continue to rise, this trend is likely to drive growth in this segment over the coming years.

The parotid gland collection segment is expected to grow at a significant CAGR during the forecast period. Salivary gland cancer, a rare malignancy originating in salivary gland tissues, often presents with symptoms like difficulty swallowing or a noticeable lump. Most salivary gland tumors are benign, typically affecting the parotid glands. Diagnosis of this condition relies on imaging tests and biopsies, including CT scans, MRIs, and positron emission tomography (PET) scans. The rising incidence of parotid gland cancer has bolstered the growth of oral sample collection and diagnostics in this segment.

Application Insights

Based on application, the disease diagnostics segment led the market with the largest revenue share of 90.6% in 2024. Saliva-based testing has proven to be a non-invasive, cost-effective, and highly reliable alternative to traditional blood sampling. This method of testing is particularly advantageous for diagnosing a range of diseases, including infectious diseases, hormonal imbalances, and cancers, as it eliminates the need for needles, reducing patient discomfort and increasing compliance. The COVID-19 pandemic accelerated the adoption of oral sampling, as it offered a safe, efficient sample collection option that minimized healthcare personnel exposure and reduced the demand for personal protective equipment. In addition, the ease of self-collection and transportability of oral samples made it ideal for widespread testing and home-based diagnostics, significantly expanding its application in disease monitoring and early detection.

Innovations in saliva diagnostic technology have further advanced the disease diagnostics segment growth. New saliva-based assays can now detect biomarkers associated with specific diseases, including cardiovascular disease and certain cancers, supporting early diagnosis and personalized treatment. As demand for rapid, accessible, and reliable diagnostics grows globally, the disease diagnostics segment is well-positioned to maintain its dominance in the market, driven by its broad diagnostic scope and patient-friendly approach.

The forensic segment is likely to grow at the fastest CAGR of 3.8% over the forecast period. Demand for saliva collection in forensic applications is rising due to advancements in DNA analysis and the non-invasive nature of saliva sampling. Saliva contains DNA, proteins, and other biomarkers that can provide critical information in forensic investigations, including individual identification, toxicology testing, and criminal profiling. Unlike blood or tissue samples, saliva can be easily collected from various surfaces, making it a practical choice for crime scenes. The increased demand for rapid, accurate, and less intrusive methods in forensic science has bolstered the use of saliva-based diagnostics, helping to streamline evidence collection and analysis in legal and investigative settings.

End-use Insights

Based on end use, the diagnostic laboratories segment led the market with the largest revenue share of 79.1% in 2024. The expansion of diagnostic laboratories and networks worldwide to address the increasing demand from customers has significantly boosted segment growth. For instance, in October  2024, Saudi German Hospital announced launch of new on-site diagnostic laboratory in partnership with Pharmatrade LLC and Roche Diagnostics. The opening of new facility is likely to increase the testing landscape within UAE fueling the regional growth.

The pharmaceutical and biotechnology companies segment is expected to experience at a steady CAGR during the forecast period, due to numerous product launches and strategic partnerships by major industry players. Collaboration between research institutions and commercial enterprises is also fostering innovation, leading to the rapid introduction of novel testing solutions tailored to specific health conditions.
