An Easier Way To Test

The Intelligent Fingerprinting VSS-GP test uses lateral flow technology to detect the SARS-CoV-2 antigen using a saliva sample.

Unlike existing COVID-19 tests that require unpleasant, invasive nose and throat swabs, our test uses a simple swab to collect a saliva sample just from the inside of the cheek.

The test strip is deliberately simple in design and engineered to keep plastic usage to a minimum – with none of the plastic casing that is usually associated with lateral flow tests.

Because it is so easy to collect a saliva sample, the test is particularly suitable for use with more vulnerable people and children.  It is available for professional use, facilitating frequent testing across a range of applications including schools, workplaces, public events, care homes, healthcare, airports and prisons.

Test results are available in 20 minutes.

How it works

The swab is used to collect the saliva sample from the inside of the lower cheek, which is then mixed with a reagent buffer that has been pre-added to the collection tube in order to release the virus. The screening test is performed by inserting the tip of the Intelligent Fingerprinting VSS-GP test strip into the sample, providing a positive or negative result at 20 minutes. No instrumentation is required.

Our test uses gold immunonanoparticle technology to enable the visual detection of bound antigen via a control line and a red line on the test strip when a saliva sample is positive for the SARS-CoV-2 Antigen.

The test comprises a four-part kit with 50 single-use COPAN CE-marked swabs for saliva collection, 50 single-use plastic collection tubes with lids, and 50 single-use VSS-GP SARS-CoV2 test strips, along with a dropper bottle containing the reagent buffer.


Accuracy & Use

Clinical precision testing of Intelligent Fingerprinting’s VSS-GP lateral flow saliva test has resulted in 100% sensitivity and specificity (n = 400 results) using RT-PCR verified samples containing SARS-CoV-2 virus (lowest viral titre Ct 28.5).
