Frequently Asked Questions

Frequently asked questions

Where have these tests been used before?


The Covid19 IgG/IgM Test has been successfully used in Germany to test over 200,000 patients and exported to other EU countries. In Germany it has routinely been used as a second more accurate screening for patients who have received a PCR swab test that has given a false negative or inconclusive result. The IgG/IgM Test is 98.7% accurate.




What’s the difference between a swab PCR laboratory test and a finger-prick blood antibody test?


The Polymerase Chain Reaction (PCR) swab test, obtains cells from the back of the throat and nose which have the viral receptors. These are laboratory processing times vary and can be 1-3 days. The PCR test results show if the patient is infected with live Covid19 virus.

The serology immunoglobulin finger-prick blood antibody test draws blood or plasma from a small finger prick, this is placed into a well in the device. A buffer is then added and the results are visible within 15-20 minutes. The finger-prick test results show the following:

- If the test has been carried out correctly (the ‘control line’)

-If the patient does not have the Covid19 antibody

-If the patient has the Covid19 antibody and has had the virus




How soon after infection would this test detect the live virus?


With Covid19 immunoglobulin M (IgM) rises in the blood to detectable levels normally between 5 to 7 days after infection, around the same time that symptoms also begin to appear. Immunoglobulin G (IgG) is also produced to bind to specific markers on the pathogen, these levels rise and are usually detectable after 7 days. Elevated levels of both of these show exposure to the live SARS-CoV-2 (Covid19) virus.

The IgG and IgM levels can take up to 7 days to show in the bloodstream after infection, this test may not show signs of a very early live virus infection. This is why authorities and businesses should test their employees regularly to see if they have had the virus.




Is the Coronavirus Testing Service accurate?


The Covid19 IgG/IgM Test (which is CE marked) has one of the highest levels of clinical diagnostic accuracy of all tests produced globally. You are also able to contact the FSI medical team and the test manufacturer directly at any time – please contact us at info@fsi.health for further details.

The Covid19 IgG/IgM test’s clinical diagnostic accuracy levels are as follows:

The MHRA’s minimum specification device criteria for Clinical Diagnostic Sensitivity for IgG is 98% at a CI of 95%.

The Covid19 IgG/IgM Test has an IgG Clinical Diagnostic Sensitivity of 98.8%, an IgG Diagnostic Specificity of 98.7% with an accuracy of 98.2%. With an IgM sensitivity of 93.7% and an IgM specificity of 99.1% at a CI of 15%.

- Please note that whilst we are providing one of the highest performing tests in the market, it is not possible to guarantee that any test kit is 100% accurate and therefore there may be instances where results obtained from the test produce a false positive or negative even when used correctly.

- If you think you may be suffering from a medical condition or if you have any queries about any medical matter, you should consult your doctor or other appropriate healthcare provider.

- You should never delay seeking medical advice, disregard medical advice or discontinue medical treatment due to the information obtained from any test kit supplied via Future Safe International Ltd.




What are the symptoms of Coronavirus infection?


Please check for updates on the UK government website and the NHS Covid19 symptom checklist here.

- A high temperature – this means you feel hot to touch on your chest or back

-A new, continuous cough – this means coughing a lot for more than an hour, or three or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual)

-A loss of smell and taste

-Shortness of breath or general breathing difficulties




What do I do if my result shows I’m positive for Covid-19 virus currently?


Should you take a PCR test and it detects current Covid19 virus you will need to self-isolate for 7 days. You will need to re-take a test to prove no live virus is present before you can return to work. Please follow NHS guidelines here for what steps to take if you feel too unwell to stay at home.

The serology immunoglobulin finger-prick blood antibody test: This is a test where blood or plasma is drawn from a small finger prick and placed into a well in the device. A buffer is then added and the results are visible within 15 minutes. The finger-prick test results show the following:

- If the test has been carried out correctly (the ‘control line’)

- If the patient is currently infected with the Covid19 virus

- If the patient is negative and does not have the Covid19 antibody

- If the patient is negative and has the Covid19 antibody i.e. they’ve had the virus

The professionally supervised Coronavirus Testing Service provided by Future Safe International uses the serology immunoglobulin finger-prick blood test.




Who might typically require the Coronavirus Testing Service?


If you think you have come into contact with somebody who may have had the virus or if you have had mild flu like symptoms or any of the Covid19 symptoms, you may have had the virus without realising and have developed the antibodies.

The current evidence is that patients who have had the virus will may go on to develop an immunity, however do not know at this point in time how long immunity will last. Immunity may also not be conferred for those with underlying immune system problems or on high dose steroids.

Your employer may have offered this test to you as a conditional process to return to work safely, whether this is to detect current live virus or to confirm antibodies to Covid19.

Proof that you are not currently infected in order to travel internationally is changing daily and we would advise you to check with your airline and departure/destination airports before you fly.

We anticipate that tests will be required before you fly (in the near future), the Government travel website provides up to date information https://www.gov.uk/guidance/travel-advice-novel-coronavirus
