How it’s done

1brush Brushing and sample collection

A Physician or a nurse practitioner performs the procedure in less than 1 minute in an office. The process involves a simple throat swab (The innovative trans-oral brushing process for direct sampling) that brushes the back of the throat in the nasopharynx for cell collection and subsequent DNA analysis. There is no need for anesthetic and can go home shortly after the procedure.

1brush Shipping of sample to the lab


Once the preserved sample is secured in the provided vial, a proprietary preservation agent preserves the sample in room temperature for up to 21 days with no DNA degradation. Using the Fedex Clinical Pak, the samples are shipped to a specificdesignated FDA/CLIA approved laboratory for DNA analysis.

1brush Results


Once the designated laboratories receive the sample, it will be cataloged, sorted and prepared for processing. A proprietary lab assay protocol – real time Q-PCR (Quantitative Polymerase Chain Reaction) is used to detect the presence of EBV DNA from abnormal cells in the patient’s sample.

Results are usually made available within 7 calendar days after collection.
