Site of Collection Insight

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.

Applications Insight

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.
