The Roche SARS-CoV-2 Rapid Antigen Test is a 'lateral-flow chromatographic immunoassay' method that's used for qualitative analysis of nasopharyngeal swab samples, in order to detect variant strains of SARS-CoV-2, the cause of COVID-19. This is achieved by observing a visual reaction that's produced on the test device by proteins which are specific to SARS-CoV-2 and which may be present in an individual's nasopharynx (nasal passage) as a marker of infection.
Lateral flow antigen tests are used effectively in both large-scale community testing programmes; in health & social care settings and by private, commercial businesses aiming to keep on top of transmission in the workplace. This innovation presents a high quality solution for screening workforces, 3rd party contractors and for testing members of the public at point of care.
By identifying those with an infection in a short turnaround, it will support you to make quick decisions and implement effective isolations and other supportive measures to disrupt the spread of disease in your organisation.
How does it work?
- Sample donors can administer a self-swab, or have it performed by a suitably trained person
- The swab should then be introduced to a pre-measured buffer liquid contained in a small extraction tube that's included with the kit, in order to bring the mucosal sample into solution
- The now liquid sample is then dropped onto a well on the test cartridge by using the nozzle cap provided in a simple, scalable protocol
- Subsequently a colouring reaction is produced on the test device at the 'T' or test line which should be read at 15 minutes, to indicate a presence of SARS-CoV-2 in the donor's sample and therefore producing a positive result. If no line appears between 15 and 30 minutes at the test line then it is a negative result. If no control line appears then the test is invalid and must be taken again
- The testing process involves an easy-to-carry-out procedure with a straightforward, visually observable result
- It has a sensitivity of 96.52% and a specificity of 99.68%, based on 426 samples from two independent study centres - with circa 98% accuracy
- Repeat testing is recommended, to increase the reliability of observing a correct result. This is entirely dependent on your individual requirements but a standard twice per week minimum is advised, due to increased transmissibility of the current SARS-CoV-2 variant strain
- Tests are for professional use only and can not be used as self-testing/ home test kits - they must be delivered by trained personnel
- Orders are made available within a maximum 5-day lead time, but generally available with next day delivery - advance notice is advised due to high demand
Generally, tests are available for small-scale orders with Next Working Day delivery, if made before 11am.
For larger scale orders, we advise a clear three to five working days notice, but will endeavour to support all requests with an urgent dispatch.
How can it help our organisation to prevent cases?
Positive results indicate that a test subject has been exposed to the virus and may have an active, early-stage infection.
It will therefore help you to make important decisions quickly – allowing management to identify and isolate cases before infections can unknowingly transmit between colleagues and other people or compromise the COVID security of your workplace. You can utilise rapid testing as part of a wider portfolio of measures to manage risks to your team, customers or people at the point of care to detect cases in both symptomatic and asymptomatic individuals.
Who can use these tests, for what purpose?
Organisations who want to regularly screen their staff, or intend to employ in-house testing can do so with this innovative testing solution – all at a fraction of the cost of private PCR lab-based testing.
In cases where publicly available tests are inaccessible or experiencing ad-hoc capacity issues – Roche Rapid Antigen Tests can empower you to deliver independent, de-centralised management of COVID-19 transmission in your workplace. This will also help to identify suitable candidates for NHS testing and allieviate pressures on public schemes.
Tests should be administered by healthcare or trained occupational health staff. This is to ensure that proper protocols are observed and that test results are accurate and reliable. It should be assumed that each person receiving the test is providing a sample that contains infective agents. All testing data must be reported to Public Health England, for all positive, negaitve and invalid results.
Support and aftercare provided?
The simple procedure can be carried out by non-medical professionals without the use of complex instruments in all manner of settings, but only when suitable guidance is provided in carrying out the test process and observing results.
We will work with you to deisgn a bespoke protocol and can support with provision of suitable PPE, as well as advising on safe disposal of clinical waste.
Our team will support you with instruction for reporting all testing data to Public Health England to ensure you're compliant with legislation - and advise on employee consent processes to ensure GDPR compliance.
PPE4Care will deliver an after-care service - we are working with partners on the delivery of thousands of lateral flow tests in programmes across the UK each week. If preferred, we are able to consult on delivering tests on your behalf with teams of staff nurses specialising in occupational health. Enquire today for more information.
