About SureScreen’s COVID-19 Rapid Test Cassette

This test is CE marked for Professional use only. SureScreen’s COVID-19 rapid test identifies the body’s response to coronavirus after the onset of infection, and gives a qualitative yes/no result within 10 minutes.

Implementing rapid screening for COVID-19 has huge time and cost savings when compared to laboratory screening, and will help to control the spread of the virus by identifying infection rapidly and accurately.

The test cassette is easy to use, needing only a finger-prick sample to function, much like a blood glucose test

As well as whole blood, the cassette can also be run with serum or plasma samples

The test kit are based on long-standing technology, using antibodies that are specific to glycoproteins produced by infected individuals in response to coronavirus
Two analytes of interest – Immunoglobulin M and G (IgM and IgG.)  Either of them showing up is a positive result
Immunoglobulins are normally produced by the immune system in response to bacterial or viral infections and act to ‘flag’ the pathogen, so that other immune cells can detect and kill it.
The IgG/IgM that the test detects are specific to the SARS-CoV-2 virus, so a positive result would indicate the patient has contracted COVID-19
What is Coronavirus?
  1. Corona – crown-like
  2. 7 types, 4 common, 3 serious
  3. SARS-CoV-2 (COVID-19), MERS-CoV (MERS) and SARS-CoV-1 (SARS)

SureScreen’s COVID-19 Rapid Test identifies the body’s response to Coronavirus after the onset of infection, and gives a qualitative yes/no result as to whether antibodies have been produced by the body within 10 minutes.

Sensitivity Specificity
96.55% 99.67%

Over all accuracy 97.8% (IgM) and 99.6% (IgG)

The test cassette is easy to use, can be used at the patient side, and only requires a finger-prick sample to function, much like a blood glucose test. As well as whole blood, the cassette can also be run with serum or plasma samples.

Importantly the test kits are CE marked for Professional use, using all EUROPEAN MANUFACTURED COMPONENTS

Key Benefits

Accurate screening tool (over 98% accuracy)

Rapid 10 minute testing time

Point of care test that can be used by the patient side

Cost effective vs. Laboratory tests

Manufacturer Support direct in the UK

Shown to improve accuracy when used alongside PCR (antigen) testing

Ideal for seroprevalence testing

No need for laboratory equipment


Diagnostics are essential to understand spread of infection
Long incubation period, and it is thought that 20% of cases are asymptomatic
Testing blood and sputum samples are the main avenues of screening.
Testing can be done to look for the antigen and antibodies
PCR (Polymerase Chain Reaction) main avenue for antigen testing but labs have faced capacity constraints pushing long timelines for results and requires lab technicians. 
Serological testing for antibodies using SureScreen’s rapid test allows a quick solution for antibody testing

How to perform the test


Experts at Guy’s and St. Thomas’s Hospital and Kings College University in London have been carrying out one of the most exhaustive examinations of antibody tests since COVID-19 emerged. They have been comparing the accuracy of tests from different companies and have published data which shows SureScreen’s performed outstandingly in critical areas. The tests have been deemed so good that the prestigious hospital is now using them daily.

The study illustrates how important quality antibody testing is for combatting COVID-19. If used in mass testing, it could be vital in showing how many people had contracted the virus and lead to a better understanding of potential immunity.

The paper states: “There is a clear requirement for accurate serology (blood) testing as a companion diagnostic to PCR-based (swab) testing… Monitoring population seroprevalence (examining who has antibodies) will be central to future public health planning based on disease susceptibility and herd immunity.”

The report goes on to state.: “For this (widescale testing) to be meaningful, it is imperative that antibody detection methods are affordable, reliable, and readily accessible.
