UK Bodily Fluid Experts Obtain CE-Marking for SARS-CoV-2 Saliva-Based Antigen Test

Intelligent Fingerprinting has announced that its saliva-based COVID-19 test now carries CE marking and is available for sale. The new VSS-GP COVID-19 Saliva Test uses a simple swab to collect saliva from just inside the cheek, providing a much easier alternative to current throat and nose tests that can cause gagging, sneezing, or distress during sample collection.

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.

Easier, more comfortable COVID-19 testing
Intelligent Fingerprinting’s reliable and easy-to-use saliva-based lateral flow test supports frequent COVID-19 testing across a range of applications, including schools, workplaces, public events such as sports or concerts, care homes, healthcare, airports, and prisons. Find out how Intelligent Fingerprinting’s saliva-based test makes COVID-19 testing much easier for people by watching this short video below: 

Keeping plastic usage to a minimum
The Intelligent Fingerprinting VSS-GP COVID-19 test strip has been carefully designed to use minimal plastic. It has none of the plastic housing usually associated with lateral flow tests, helping to significantly reduce its environmental impact. The test strip is around 95% lighter than traditional lateral flow devices, contributing significantly to the reduction of the environmental impact of packaging and transportation.

Intelligent Fingerprinting’s Executive Chairman, Philip Hand explains: “Regular COVID-19 testing will continue to be part of our everyday lives for the foreseeable future, so it’s essential that we remove potential barriers to testing and make the whole process as simple and comfortable as possible. Our saliva-based test directly addresses this challenge, combining much simpler sample collection with high levels of accuracy. I’m delighted that our test is now CE marked, and we anticipate strong demand for saliva-based testing from markets around the world.

“We have already scaled up production capacity at our Cambridge, UK, manufacturing facility utilising existing equipment, have ISO 13485 quality control in place and, given initial demand and distributor agreements, we will be able to produce our new saliva-based COVID-19 tests at a rate of four million a month by the end of 2021. We also anticipate working with a range of distribution partners to make this test available across multiple markets,” he added.

Accurate results
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 samples (lowest viral titre Ct 28.5). CE marking has been achieved under the In Vitro Diagnostics Directive. The saliva-based test has been developed in the UK by Cambridge-based Intelligent Fingerprinting, developers and manufacturers of the world’s first and only fingerprint sweat drug test. The new COVID-19 test takes advantage of the company’s proven lateral flow technology expertise.

How it works
A 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 into the solution. The screening test is performed by inserting the tip of the VSS-GP test strip into the sample, providing a positive or negative result at 20 minutes. No instrumentation is required. The 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.
