About PCNT

Point of Care Nano-Technology, Inc. (PCNT) delivers advanced drug testing solutions built for law enforcement, clinical labs, and workplaces. Founded in 2010 and based in Davenport, Florida, the company began in animal nutrition and now leads in saliva-based testing.

PCNT’s EZ Saliva products offer speed, precision, and reliability in a simple, compact format. The EZ Solution™—developed with Johnson & Johnson—stimulates saliva, stabilizes the sample, and enhances detection of drugs like THC. Each test requires less than five minutes from collection to completion.

This patented mouth rinse and buffer is included in every collection, boosting sample volume, improving accuracy, and supporting consistent lab results. It also prevents dry mouth issues and keeps samples stable without refrigeration.

As national guidelines shift to accept saliva testing, PCNT remains ahead—engineering tools built to meet evolving standards and real-world demands.
