Our Total Antibody test can confirm previous exposure by detecting both IgM and IgG antibodies produced by your body as a response to the infection. This test is effective 14 days after symptoms have appeared.
We need to get life back to normal again, but the only way to do that safely and sustainably is with large-scale testing.
We are a Not For Profit organisation offering COVID-19 testing at cost, making our tests the cheapest available.
Our tests are on offer to anyone in the UK and are carried out by the same labs as commercial providers but at a fraction of the price since we’re not aiming to make a profit
When exposed to SARS-CoV-2, the virus that causes COVID-19, our immune systems start to produce antibodies to fight off the virus. This test can detect infection after 7 days, but is most effective 14 days after symptoms appear. By looking for these antibodies, this test will help you determine whether or not you have been exposed to the virus.
We have not yet gathered sufficient evidence to show whether or not the presence of these antibodies confers immunity to patients, and so it is still important that you continue to adhere to social distancing guidelines even if you have antibodies.
If you are worried about a recent exposure to COVID-19, our RT PCR (real time polymerase chain reaction) test allows you to detect any signs of infection starting five days from potential exposure. This test looks for the presence of genetic material from the COVID-19 virus using a throat/nose swab.
By looking for the genetic information of the virus, this test allows you to determine whether you are infected with the virus at the time of taking the test, provided you take the test within 5 days of your symptoms starting.
COVID-19 is an infectious disease caused by a newly discovered virus from a family of viruses called coronaviruses. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without special treatment. Older people, and those with some underlying medical problems, are more likely to develop a serious illness.
If you currently have symptoms of a COVID-19 infection, you should be self-isolating at home and can seek an antigen or RT PCR test. If you suspect you had COVID-19 in the past (at least 21 days ago) or were exposed in the past to someone who had COVID-19 you can be tested for antibodies, to see if you were infected with COVID-19. Even if you had no symptoms, at the time, getting an antibody test is worthwhile, as research suggests that 4/5 people with COVID-19 show no symptoms at all.
The test has been validated in a clinical setting by Roche and subsequently CE marked. Roche claims their test is 100% sensitive and 99.8% specific. This means that if you’ve got COVID-19 antibodies, this test can find them with 100% certainty. Additionally, you can rely on a negative result meaning that you have no COVID-19 antibodies with a near 100% certainty. The manufacturer’s release note published for the FDA EUA is here. In addition Public Health England found the test to be 93.9% sensitive and 100% specific (see the evaluation here) for samples taken ≥21 days post symptom onset. (For an explanation of sensitivity and specificity please refer to this video).
Roche has claimed that their test has a 100% specificity, meaning it is very unlikely to deliver a false positive (i.e. receiving a positive result, despite in reality not having COVID-19 antibodies). False negatives however may occur if the test is taken too soon after a possible COVID-19 infection. The antibodies that the test detects only start to develop from around 14-21 days after the initial infection so if a test is taken before this point, a false negative might occur. Testing For All declines all responsibility for false negative tests.
The NHS provides free antigen tests for individuals who believe they have COVID-19 symptoms, either at drive through centres or “at home” kits. These are tests to see if you are currently infected with, and potentially transmitting the disease. The official NHS website states that an individual should only apply for an NHS COVID-19 antigen test if they ‘have coronavirus symptoms or have been asked to get tested.’ If you wish to have a test for other reasons, such as travelling to another country, the NHS recommends purchasing a private test. More information is available here. Antibody testing via the NHS is currently offered to NHS and care staff and some hospital patients and care home residents, but is not widely available.
Testing For All is a not-for-profit organisation, and charges for the test based on a forecast of total testing we expect to perform in a given month, set at a level to cover our operational costs of running the testing service. We are committed to keeping the price of testing as low as possible, and the current price is likely to fall over time as our scale of testing increases.
We aim to return your Antibody test result within 2-3 working days of you posting it to the laboratory, but sometimes it may take up to 5 days to be returned. Together with our lab partners, we are striving to keep time to result as low as possible.
Yes, this test is designed to be taken in the comfort of your own home.
This test can’t tell you if you’re now immune to COVID-19. This is still a very new virus, and we don’t know how long these antibodies stay in your system. This is why it’s important to continue to follow government guidelines on social distancing. For the most up to date advice on COVID-19 and immunity, follow the government’s advice outlined here
