Market Dynamics

Market Drivers

  • Growing Number of Approvals for Saliva Collection Devices

The increase in approvals for saliva collection and diagnostic devices is due to their growing need to diagnose life-threatening diseases rapidly. For example, in January 2015, DNA Genotek, an OraSure Technologies, Inc. subsidiary, received approval from the US Food and Drug Administration (USFDA) for genetic Oragene Dx saliva collection test kits. The saliva collected using these kits is used to screen for Bloom Syndrome, a genetic disorder.

Furthermore, 23andMe, Inc. works with DNA Genotek to manufacture a genetic Oragene Dx saliva collection test kit. Later, in February 2015, the USFDA approved the proposal of 23andMe, Inc. to market genetic Oragene Dx saliva collection test kits. The growing demand for salivary diagnostics has encouraged several companies to invest in the market and develop products, kits, and devices for saliva collection and testing resulting in an upsurge in the global growth of the saliva collection and diagnostic market.

  • Cost-Effective Saliva Collection and Diagnostic Methods

Collecting saliva DNA is less costly for genetic research than other types of testing, such as blood and urine tests. As per the CRN Pharmacovigilance Project, the cost of a saliva collection kit of Oragene is around USD 20, while the price of a blood collection kit is nearly USD 100. However, according to DNA Genotek, saliva collection is 48% less costly than blood collection. There is no need for transportation and storage of saliva samples from collection to processing. In contrast, the blood samples require dry ice, overnight shipping, and freezers, while the saliva samples can be stored at room temperature and transported via traditional methods. Hence, the saliva collection method is less costly than blood collection, which is one of the factors fueling the market's growth.

Market Restraint

  • Supply of Defective and Faulty Products

The supply of faulty and defective products is expected to hamper the global saliva collection and diagnostics market. In June 2018, Dante Labs delivered a faulty saliva collection kit in Switzerland. The tube portion where saliva was to be deposited had a bubbly liquid on its brim and was sealed in a biohazard bag. Furthermore, the kit did not contain any return instructions. This faulty device will likely cause a dip in the global saliva collection and diagnostics market.

Market Opportunities

  • Technological Advancements like Saliva-Based POCT Devices

The salivary diagnostic is an evolving field for advancing the point of care technology (POCT). The need for the development of saliva-based POCT devices is due to the potential of saliva in the early detection of oral and systemic diseases such as bacterial and fungal infections, cancers, and genetic disorders. In addition, point of care technology is a medical device used to conduct testing outside the laboratory, including at the patient's bedside, the doctor's office, and the patient's home. The increasing research and development in disease prediction by saliva testing provide enormous opportunities for market players to enter the global saliva collection and diagnostics market.

Technological progress has permitted a high level of studies to be performed at a previously unrealized scale and is serving to propel the discovery and approval of salivary disease biomarkers. Miniaturization technology provides a new avenue for point-of-care diagnostics among the newly developed technologies. This will detect multiple biomarkers in parallel and allow simultaneous research and development studies for various disease conditions. Such new technologies would significantly change the landscape of point care diagnostic technology and boost the saliva collection and diagnostics market.

Segmental Analysis

The global saliva collection and diagnostic market is segmented into site of collection, application, and end-user.

Based on the Site of Collection

The global saliva collection and diagnostic market is divided into parotid glands collection, submandibular glands/sublingual glands collection, minor salivary glands collection, and others.

The submandibular glands/sublingual glands collection segment is the highest contributor to the market and is expected to grow at a CAGR of 11.62% during the forecast period. Just below the inferior border of the mandibular body is where the submandibular gland is located. It is best palpated bi-manually with one hand on the lateral floor of the mouth and the other on the submandibular gland. The sublingual glands are almond-shaped and lie on the bottom of the oral cavity. The submandibular gland produces around 70.0% of nonstimulated saliva. In addition, sialoliths or salivary stones are the most prevalent disorder affecting the salivary glands in middle-aged adults. Approximately 80% of salivary sialoliths originate in the submandibular gland, followed by the parotid gland, which accounts for 6–15%, and the minor or sublingual salivary glands, which account for 2%. The rising incidence of sialolithiasis may contribute to the segment's expansion over the forecast period.

The parotid gland lies on the lateral surface of the mandibular ramus and folds itself around the posterior border of the mandible. Cancer of the salivary glands is a rare tumor that originates in the salivary gland tissue. The parotid glands are home to the most benign salivary gland malignancies. Imaging tests or biopsies, such as CT scans, MRIs, and positron emission tomography scans, are used to diagnose this illness. The rising incidence of parotid carcinoma has contributed to expanding the saliva collection and diagnosis market. Later in May 2020, the U.S. Food and Drug Administration (FDA) authorized the first diagnostic test with the option of using home-collected saliva samples for COVID-19 testing.

Based on Application

The global saliva collection and diagnostic market is divided into disease diagnosis, forensics, pharmaceutical and biotechnology companies, and others.

The disease diagnosis segment owns the highest market share and is expected to grow at a CAGR of 11.71% during the forecast period. Saliva is a non-invasive and safe source and could be used as a substitute for blood in diagnosing and prognosis of diseases. Oral diseases diagnosed by saliva are carries, periodontal diseases, oral cancer, and Sjögren's syndrome. The increased number of streptococcus mutans and lactobacilli in saliva has been associated with an increased prevalence of caries and root caries. In addition, periodontal diseases have been associated with increased levels of aspartate aminotransferase (AST) and alkaline phosphatase (ALP). Thus, salivary AST is used as a marker for monitoring periodontal disease. Therefore, the increasing diagnosis of diseases by saliva is boosting the global saliva collection and diagnostic market.

An increasing number of saliva collection device approvals and new launches by pharmaceutical companies, along with the availability of new tools for saliva collection and diagnosis, especially during the ongoing COVID-19 pandemic, is fueling the global saliva collection and diagnostic market. For instance, in Spectrum DNA, in April 2020, declared that the Spectrum DNA SDNA-1000 Whole Saliva Collection Device, researchers from RUCDR Infinite Biologics at Rutgers University successfully validated saliva as a viable biosample source for COVID-19 detection when compared to nasopharyngeal or oropharyngeal swabs.

Based on End-User

The global saliva collection and diagnostic market is divided into hospitals and dental clinics, diagnostic centers, investigation laboratories, and others.

The hospitals and dental clinics segment is the highest contributor to the market and is anticipated to grow at a CAGR of 10.93% over the forecast period. The hospitals and dental clinics segment market growth is majorly attributed to the increasing number of patients getting monitored with chronic diseases. Since advanced and complete treatments are available in the hospital, patients usually prefer to get treated at the hospital. Dental clinics are also medical care centers that provide dental services. Further, hospitals are rapidly adopting new technologies and procedures to provide effective treatments, which are expected to contribute to the market's growth.

A diagnostic center is a place that offers diagnostic services to medical professionals or the public. This segment's market growth is due to the increasing number of people diagnosed at diagnostic centers. Additionally, a growing number of diagnostic centers providing innovative diagnostic techniques contributes to the market's growth.
