About COVID-19 
Instant Test

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 home blood glucose test. As well as whole blood, the cassette can also be run with serum or plasma samples.
Got questions?

We can help!

Can the test show if I have Coronavirus infection now?

Yes, the test will show your IgM and maybe IgG will be positive.

Antibody tests are primarily used to help diagnose a current or recent infection. They detect two different classes of antibodies produced by the body in response to an infection - IgG and IgM. Diagnosis may require a combination of these tests because the body's immune system produces varying levels of antibodies over the course of the illness. 

Can the test show if I have had Coronavirus previously?

Yes, the test will show your IgG will be positive.

After a few months, IgM antibodies fall below detectable levels. IgG antibodies are produced more slowly in response to an infection. Typically, the level rises with an acute infection, stabilises, and then persists long-term. Individuals who have been exposed to the virus previously maintain a level of IgG antibodies in the blood.

How does the test cassette work?

The test is a lateral flow immunoassay test and operates in a similar way to a pregnancy test. Embedded into the test strip are antibodies that bind to a COVID-19 specific biomarker, Immunoglobulin G (IgG), and another infection biomarker, Immunoglobulin M (IgM). When a sample (blood, serum or plasma) is added to one end of the test, it flows along the test strip and interacts with these antibodies. If the patient has contracted COVID-19, the biomarkers in their blood will bind to the antibodies on the test strip, leaving a visible test line. If the patient doesn’t have COVID-19, no biomarkers should be present in their blood and no test line will be visible. There are separate test lines for IgG and IgM and only one needs to be visible for a positive result.

What are IgG and IgM?

Immunoglobulins are antibodies themselves and are part of our immune system. When we get an infection, such as COVID-19, immunoglobulins are produced, which attach to the virus and activate the rest of the immune system to attack and clear the virus. IgM is the first immunoglobulin to be produced and is a general antibody that can bind to many different types of pathogen. The presence of IgM is an indicator of early infection. IgG is a more specialised antibody that specifically binds to the SARS-CoV-2 virus. The presence of IgG is an indicator of past or previous infection (usually 7 days or longer after infection).

Is the test specific for COVID-19?

The IgG that the test detects is specific to COVID-19, so a positive result would indicate COVID-19 infection. Although the IgM is a more generalised antibody, its presence, combined with IgG and/or the common symptoms of COVID-19, would also indicate infection with the novel SARS-CoV-2 virus. The test can be used for primary and secondary diagnosis of COVID-19.

What samples can I use?

The test cassette will work with whole blood, plasma or serum. Capillary blood is the easiest to obtain via a finger pinprick, however, venous blood obtained via venepuncture is also suitable. The type of sample will not affect the sensitivity or accuracy of the test.

Can I pay by card?

Yes, we use a secure payment card gateway to take credit/ debit card payments.

What is the buffer solution for and can I use any buffer with the test?

The buffer solution has two functions. It acts as the carrier for the sample, allowing it to laterally flow along the test strip, and it maintains a constant sample pH as it flows, preventing degradation of the biomarkers and the antibodies. We recommend that you only use the solution provided with the test kits, as other ones may affect the accuracy of the test.

What do the results mean?

The test strip has three different lines; one for IgG, one for IgM and one control line. There are four different valid results:

* IgG + Control - The sample is positive for IgG and therefore positive for COVID-19
* IgM + Control - The sample is positive for IgM. This means the patient is in the early stages of an infection and combined with the common symptoms, is positive for COVID-19
* IgG + IgM + Control - The sample is positive for both IgG and IgM and therefore positive for COVID-19
* Control only - The sample is negative

If the control line does not appear, the test is void and should be repeated, irrespective of how many test lines are visible.

What should I do if I test positive?

If you test positive, you should follow your country’s government’s advice on COVID-19 infection. This usually means self-isolation for 7 days, avoiding contact with others and remaining hydrated. Most cases of COVID-19 are mild and recovery only takes a few days, so there’s no need to panic. Speak to your healthcare practitioner for further advice.

What if I test negative?

A negative result means the biomarkers are not present in your blood, but you should still exercise caution, as you may still be in the early stages of infection (before IgM levels rise to a detectable level). If symptoms develop, follow the protocols as above and retest as necessary. If symptoms do not develop, it is unlikely you have COVID-19 but should still follow strict hygiene procedures. Ensure you wash your hands regularly, avoid social gatherings and work from home if possible. There’s no need to retest unless you suspect you have contracted the infection and are displaying symptoms.

What if I test positive but don’t display any symptoms?

In this case, there are two options. Either you are infected and may begin to display symptoms in the next few days, or you are infected but are asymptomatic (you won’t display symptoms). In both cases, you should treat it as though you are positive for the virus and should follow the appropriate healthcare guidelines. Speak to your healthcare practitioner for further advice.

So can the test detect asymptomatic patients?

Yes, the test will be able to detect IgM/IgG in asymptomatic people, as they will have an immune response even though they don’t display symptoms. The timeline of infection will be the same as someone displaying symptoms.

What if I test negative but display symptoms?

If you have the common symptoms of COVID-19 (fever and cough), you likely have contracted the infection and should self-isolate. It is likely your IgG/IgM levels haven’t risen to a detectable level yet. You can be tested again 24 hours later for confirmation if required. Speak to your healthcare practitioner for further advice.

I didn’t read the results after 10 minutes. What should I do?

For the result, the window of accuracy is 10-15 minutes after you add the sample and buffer solution. If you forget to read the results after this time, the test may not be accurate and you should repeat it.

What is the shelf-life of the test cassette?

The shelf-life is 18 months from the date of manufacture. The product expiry is printed onto the packaging for reference. Do not use after the expiry date.

How should I store the tests?

The recommended storage temperature is 2 – 30°C, however, we do not recommend you store them in the fridge, unless there is a risk of them overheating. Do not freeze the test cassettes or buffer solution. Tests should be performed at room temperature (15 – 30°C), so if you have stored tests in the fridge, you should allow them to reach room temperature before performing a test.

Do any medications, drugs or other proteins in the blood affect the test result?

To date we have tested numerous common pharmaceuticals, none of which have interfered with the test. Also, Rheumatoid Factor does not interfere with the test, hence we currently see no cross-reactivity issues. We are looking at more drugs and will update customers accordingly.

How accurate is the test?

A clinical study was conducted in Wuhan, China, where we compared the test cassette to conventional laboratory tests for COVID-19 diagnosis, which also detected the presence of IgG/IgM in 902 blood samples. We obtained the following results:

* Sensitivity > 91%
* Specificity > 99%
* Accuracy > 97%

This clinical study is evidence of the usability and effectiveness of the test.

Will IgG and IgM remain in the blood after I’ve recovered from COVID-19?

There is some evidence that IgG/IgM remains in the blood after recovery to prevent reinfection. We have tested some patients and noticed that they still test positive for at least 33 days after first displaying symptoms. You won’t be infectious after you recover, even if you test positive, but you should still be cautious as long term immunity has not yet been confirmed and reinfection may still occur.

Can babies and young children be tested?

Yes, there are no issues with testing babies and young children.

Can pregnant or breast feeding women be tested?

Yes, there is no harm to the mother or baby when performing a test.

Is there anyone that shouldn’t be tested?

No, the more people that are tested, the better it will be to understand the spread of the virus, which will result in better measures being taken to prevent its spread. However, as the test requires a blood sample, anyone with a blood-related health condition (such as haemophilia) should discuss this with a healthcare professional before performing a test.

Is the test CE marked? Does it have IVD certification?

Yes, the COVID-19 test is CE marked for professional use and is therefore a registered IVD device.

Is the product already on the market, e.g. in Great Britain?

This is a relatively new test but is now being used successfully in many countries around the world.

Has the test been accredited by the NHS or Public Health England (PHE)?

The COVID-19 test is CE marked for professional use and is therefore suitable for use by a healthcare professional. This test is very new to the market and is an excellent and accurate way to quickly detect COVID-19.

Do you have a confirmation lab test for Coronavirus to confirm positive samples?

This is something we are looking at, but we would recommend any non-negative results are referred to a medical health practitioner through the NHS who have access to confirmatory testing through a laboratory. Phone 111 from any mobile or landline or visit https://111.nhs.uk/ for further information. Do NOT visit your local surgery to avoid spreading any potential infections.

Can this be performed in a private setting?

You hereby when ordering this test confirm you are a medical professional or a private individual that shall have the test performed by an approved medical professional in a clinical setting as per MHRA guidelines.

What is a Professional Test*

A test that has been tested rigorously and received certification and advisable as per MHRA and clinical guidance to be performed by a medical or healthcare professional in a clinical setting.
