Market Scope

Market Dynamics

Driver

Cost-effective collection and diagnostic offering

Collecting saliva DNA is not that expensive compared to other kinds of testing, such as blood and urine tests. Saliva samples do not need specific transportation and storage facilities from collection to processing. However, the blood samples need freezers, dry ice, and overnight shipping, while samples of saliva can easily be stored at the current temperature and transported via conventional methods, which makes the whole saliva collection process cheap.

• In November 2022, Quest Diagnostics announced the completion of its previously announced acquisition of select assets of LabCare Plus, the outreach laboratory services business of Summa Health, a big integrated healthcare organization.

Restraint

Complex sample treatment

Saliva is a high blend of many substances such as proteins, enzymes, nucleic acids, and other hormones. The complexity of this mixture can make it difficult to characterize and isolate salivary EVs, which sometimes can show different detection results. Moreover, there are many hurdles in reliably supplying the required materials for saliva collection and diagnostics.

Opportunity

Advancements in saliva-based POCT devices

The requirement for the advancement of saliva-based POCT devices is because of the ability of saliva the rapidly detect systemic and oral diseases like cancers, fungal and bacterial infections, and genetic disorders. Furthermore, the growing R&D in disease prediction by testing providers offers numerous opportunities for key players to enter the global saliva collection and diagnostics market.

• In November 2023, PCL, a Kosdaq-listed in vitro diagnostic medical device company, declared that its AI-based point of care testing (POCT) device, Pclok II Prep Universal, distinguished by the ability to diagnose various cancers, viruses, chronic diseases, and infectious diseases, has received U.S. FDA clearance.
