Non-invasive Covid-19 antigen LFT with rapid results
- Only requires nostril swabs
- Results in 15 minutes
- Identify a current Covid-19 infection
- Easy to use
A premium non-invasive antigen lateral flow test with rapid results
Our non-invasive LFT identifies an active COVID-19 infection using just a nose sample. Results are available within 15 minutes, with no laboratory testing required.
Based on the technical data we’ve gathered from analysing multiple LFT devices, ours is one of the most advanced non-invasive antigen LFT devices available. Our devices offer a high diagnostic specificity and diagnostic sensitivity. This allows identification of the virus from 14 days after initial exposure or after the onset of symptoms, while minimising the risk of false negative results.

How does the non-invasive lateral flow test work?
How do I understand the lateral flow test results?
A total of two detection lines are possible. The control (C) line appears when the sample flows through the testing device cassette, after the buffer liquid containing the sample has been added.
The test result is negative if only the quality control line (C) appears. This means no COVID-19 specific antigens have been detected.
The test result is positive if the quality control line (C) and the antigen detection line (T) appear. This means COVID-19 specific antigens have been detected.
Where this is the case, the tested individual must follow the latest government guidance on quarantining and self-isolation.
If the quality control line (C) does not appear or it takes over 15 minutes for the line(s) to appear, the test results are invalid.
Frequently Asked Questions
What is the benefit of the AlphaBiolabs non-invasive COVID-19 antigen lateral flow test?
Our non-invasive LFT is one of the most sensitive and specific antigen lateral flow devices available, which helps to minimise false negatives.
What’s the difference between the lateral flow test and the RT-PCR test?
The COVID-19 LFT detects specific proteins situated on the cell membranes of the COVID-19 virus. These proteins are known as antigens and can be quickly detected, within 15 minutes, using the lateral flow immunoassay device.
Our non-invasive LFTs only require a swab sample from the nose. The RT-PCR test requires swab samples to be taken from both the nose and throat areas.
Both the LFT and the RT-PCR tests are effective methods for detecting the presence of the COVID-19 (SARS-CoV-2) virus but the LFT delivers quicker results.

Is the lateral flow test CE marked?
Is the lateral flow device approved by the MHRA?
How accurate is the non-invasive antigen lateral flow test?
Is it possible to get a false negative result?
- insufficient viral load present in the nasal areas when sample collection occurred
- incorrect sample collection procedure (if the sample collection is not uncomfortable, it is highly likely that the sample has been incorrectly collected)
- a new variant of SARS-CoV-2 that may circumvent the specific lateral flow device
It is therefore vital that the sample collection is carried out in line with our instructions contained within the kit and the most appropriate lateral flow devices are used.
If you believe you have received a false negative result, you can either perform the test again a couple of days later, or order a ‘back to lab’ PCR test.
What is an antigen?
How reliable is the non-invasive antigen lateral flow test?
We perform regular testing at our in-house PCR laboratory to ensure that the lateral flow devices we provide are best matched to minimise false negative results.
What should I do with a positive COVID-19 result?
What if I get a positive result but don’t feel unwell?
If you do start to experience COVID-19 symptoms and/or begin to feel unwell, visit the NHS 111 webpages for the most up-to-date advice at www.nhs.uk/using-the-nhs/nhs-services/urgent-and-emergency-care/nhs-111/ or call 111.
