COVID-19 Lateral Flow Test

Convenient, affordable Fit to Fly lateral flow

This rapid antigen test can confirm your COVID-19 status for fit-to-fly.

The test is performed from home and you typically receive your certificate within 1-2 hours.

Please note that this test is not suitable for countries which do not accept lateral flow antigen testing for entry.

Some countries require that this test is supervised over telemedicine. See the FAQ below to select the correct type of test for your destination.

If you require a supervised test, please note that you will be required to book a Zoom call with our team in advance of your flight. Instructions on how to book will be sent to you when the order is placed.

Our telemedicine team operate between the hours of 10 am – 12 noon and 2 pm – 4 pm, 7 days a week. Please contact customer support if you require a slot outside of these times.

Yes. The product is designed so that it may be bought and shipped by a different person to the person that uses it.

The product must be activated when it is used at, and the name and personal information that appears on the certificate is the name of the person that activated it.

The name of the person who activates the kit at appears on the certificate, not the person who bought or received it.

What is needed to join the video call?

A suitable smart phone or laptop capable of joining a Zoom call

What should I do to prepare?

  • Test joining a Zoom call by visiting
  • Have your Sample ID card from inside your kit
  • Have your unopened lateral flow packet with you

This test will tell you whether or not you are currently carrying SARS-CoV-2, the virus that causes COVID-19, regardless of whether you are displaying symptoms. This test is sensitive enough to detect both symptomatic and asymptomatic individuals. If found positive, you should immediately follow the current best practise guidance provided by the NHS, which we will provided to you with your results.

Those testing positive must seek a confirmatory PCR test with NHS Test and Trace

Performance of the SARS-CoV-2 Antigen Rapid Test was established with 605 nasal swabs collected from symptomatic individuals who were suspected of COVID-19. The results show that the relative sensitivity and the relative specificity are as follows:

Relative Sensitivity: 97.1% (93.1 -98.9%)*

Relative Specificity: 99.5% (98.2% – 99.9%)*

*95% Confidence Intervals

Stratification of the positive samples post onset of symptoms between 0-3 days has a positive percent agreement (PPA) of 98.8% (n=81) and 4-7 days has a PPA of 96.8% (n= 62).
Positive samples with Ct value 33 have a higher positive percent agreement (PPA) of 98.7% (n=153).

Limit of Detection (LOD)
The LOD of SARS-CoV-2 Antigen Rapid Test was established using limiting dilutions of an inactivated viral sample. The viral sample was spiked with negative human nasal sample pool into a series of concentrations. Each level was tested for 30 replicates. The results show that the LOD is 1.6*10² TCID50/mL.

This means that you probably have the virus.

Even if you have not had symptoms of coronavirus, you must now self-isolate for 10 days from the day after your test date.

You must obtain, take and return a free follow up PCR test from NHS T&T to confirm this. You can access your confirmatory PCR test by visiting or by calling 119. This test will be free of charge will be sent to you as a home test kit, you MUST take this test for this purpose. If this confirmatory test is negative, you no longer need to self-isolate.

You may be contacted for contact tracing and to check that you, and those who you live or are travelling with, are self-isolating.

You must not travel, including to leave the UK, during self-isolation.

Contact 111 if you need medical help. In an emergency dial 999.

This guidance above is provided by UKHSA for private providers of Lateral Flow Device testing.

Yes, this service is designed for Fit to Fly, where a country accepts either a supervised or unsupervised rapid antigen test. The key features are:

  • Fit to fly compliant certificate included
  • High quality antigen test that achieved a pass in Phase 3a of DHSCs rapid test evaluation
  • Lateral flow manufactured by a leading UK manufacturer – Surescreen Diagnostics
  • For Supervised Fit to Fly, the service includes supervision of the sampling process via telemedicine (Zoom).

You are required to take a nasal swab sample. The swab is inserted approximately 2.5cm into your nose. The swab is then inserted into a special buffer liquid and then dropped onto the lateral flow cassette for testing. Your result appears on the cassette approximately 15 minutes later. You will then need to upload a photo of your lateral flow cassette via in order for us to validate the test and issue a result certificate. 

If you are travelling to the US or any other countries requiring a supervised lateral flow test, the above sampling process is to be supervised on a video call with one of our trained staff.

Please use the test kit within 3 months of purchase as we cannot guarantee to offer the result verification service after this time.

We issue a certificate alongside your result. The report will show your name, your date of birth, a doctors signature and GMC number, date the sample was taken and your result. This testing is overseen by the clinical advisory team at Testing For All.

This document is intended to be a fit to fly certificate.

No, this test checks for current infections only though will typically return a positive result for up to 25 days post infection. In order to find out whether you have been exposed to COVID-19 in the longer past and have developed antibodies, you can take our immunity tracker test

  1. The SARS-CoV-2 Antigen Rapid Test is for self-testing use only. The test should only be used for the detection of SARS-CoV-2 antigens in nasal swab specimens. The intensity of the test line does not necessarily relate to the SARS-CoV-2 viral load in the specimen.
  2. A false-negative test may result if the level of antigen in a sample is below the detection limit of the test or if the sample was collected incorrectly.
  3. Test results should be looked at with other clinical data available to the doctor.
  4. A positive test result does not rule out co-infections with other pathogens.
  5. A positive test result does not differentiate between SARS-CoV and SARS-CoV-2.
  6. A negative test result does not rule out other viral or bacterial infections.
  7. A negative result, from an individual having symptoms beyond seven days, should be treated as likely negative and confirmed with a molecular assay, if necessary.
  8. The usability of self-testing by an individual aged under 18 years has not been determined. It is suggested that individual under 18 years of age should be tested by an adult.
  1. Read the SARS-CoV-2 Antigen Rapid Test Package Insert carefully before performing a test. Failure to follow directions may produce inaccurate test results.
  2. Do not use the test after the expiration date shown on the pouch.
  3. Do not eat, drink, or smoke 30 minutes before and during the test.
  4. Do not use the test if the pouch is damaged.
  5. All used tests, specimens and potentially contaminated materials should be discarded according to local regulations.
  6. The test line for a high viral load sample may become visible within 15 minutes, or as soon as the sample passes the test line region.
  7. The test line for a low viral load sample may become visible within 30 minutes.
  8. Do not collect the nasal swab specimen when nosebleed happens.
  9. Small parts are a choking hazard.
