PCR Swab test
Our PCR test checks for the presence of the virus in your system. The PCR test is most appropriate during the earliest stages of exposure to the virus, approximately 1-11 days, and should be undertaken when someone suspects they have Covid-19, or if they believe they have been recently exposed to it. The test can detect Covid-19 even if the individual is asymptomatic.
IgG Antibody test
Our antibody test accurately detects a person's IgG antibody response to Covid-19: if a person tests positive for the antibody, this means they have had Covid-19. The antibody test consists of a small blood sample and is recommended for use from 21 days after exposure or the onset of symptoms(14 days in the case of venous blood sample).
Qured offers two tests for Covid-19: a rapid PCR RNA test and an IgG antibody test. Broadly speaking, the difference between the two tests can be understood as: 'Do I have it?' (PCR) and ‘Have I shown a detectable IgG antibody response?' (Antibody). Qured’s PCR test can identify Covid-19 in those who suspect they currently have the virus, from the earliest pre-symptomatic stages of the infection. Qured’s Covid-19 antibody test can identify those who have shown an immune response to the virus, once they have recovered from suspected symptoms. For more information, please see our dedicated PCR and Antibody test pages.
The PCR test detects whether you have the virus on board. This is typically from the day of exposure till the day the virus has been shed from your system (usually up to 14 days but can be shorter or longer in some cases). It should be undertaken when someone suspects they have Covid-19, or if they believe they have been recently exposed to it. The test can detect Covid-19 even if the individual is asymptomatic.
The antibody test detects a person's IgG antibody response to Covid-19: if a person tests positive for the antibody, this means they have likely had Covid-19. In the early days of an infection when the body’s immune response is still building, the IgG antibody may not be detected. Therefore this antibody test is recommended for use only after approximately 21 days from the onset of symptoms or a positive PCR test.
If you opt for a venous blood sample to be collected from a healthcare professional at your home, the laboratory recommends the test can be used from 14 days after onset of symptoms or positive PCR test.
If our PCR test is positive for Covid-19 and you recover, or if our antibody test is positive for IgG antibodies, the test results each indicate that you have been exposed to the virus and developed antibodies against it. There is still a great deal about Covid-19 immunity that we do not yet fully understand. For example, we do not yet know that just because someone has developed antibodies, that they are fully protected from reinfection, or how long any immunity lasts. If your IgG test is positive it means you have had Covid-19 exposure sufficiently to make an antibody response to the virus. There is currently no scientific evidence confirming if the presence of antibodies correlates to immunity or how long the antibodies will last for.
If your IgG test is negative, it means you have not been exposed sufficiently to make an antibody response or there has not been sufficient time for the body to make an antibody response. There is also a possibility that your body made an antibody response which has not been sustained and is therefore not detectable when it was tested for. Some patients with other underlying health conditions specifically related to their immune system may also not be able to mount a detectable or sustainable immune response and therefore may test negative. Please note that some people may not develop IgG antibodies even after proven infection with Covid-19 and will therefore test negative.
We are an established on-demand doctor service that is regulated by the Care Quality Commission. We have worked hard to source the most reliable tests currently available and all packages include the offer of a telephone consultation with a GP, so you can be sure you are getting expert medical advice.
The performance of these tests is described by their “sensitivity,” or their ability to identify those with infection with or antibodies to Covid-19 (true positive rate), and their “specificity,” or their ability to identify those without infection with or antibodies to Covid-19 (true negative rate).
The PCR test diagnoses infection with Covid-19 by identifying the presence of the RNA virus using reverse-transcriptase PCR. The assays used at our partner laboratory show a minimum sensitivity of 98% and a specificity of 100%, with no cross-reactivity with other viruses. The IgG antibody test currently used by our laboratory reports a sensitivity of at least 97.5% and a specificity of 100%.
Each test is CE marked and authorised for use in UKAS accredited laboratories.
It is important to distinguish between different types of antibody tests. Several rapid tests currently being marketed by private practitioners are rapid lateral flow immunoassay (LFIA) devices which provide a quick, point-of-care approach to antibody testing. We are not using these tests, our test detects IgG antibodies only and conducted by a UKAS accredited lab. A recent study by the National COVID Scientific Advisory Panel concluded that the performance of current LFIA devices is inadequate for most individual patient applications, however lab-based tests can be calibrated to be specific for detecting and quantifying Covid-19 IgM and IgG antibodies, and are highly sensitive for IgG.
The PCR and antibody tests used by our lab test have each received a CE mark showing it complies with EU safety rules and can be used in UKAS accredited labs in the UK. All of our tests are conducted in UKAS accredited labs.
Our laboratory partners normally process and return results within 2-3 working days from receiving the test at the laboratory. However, from time to time the laboratories may have to prioritise NHS demand. Qured will inform you of your results via the email provided as soon as we receive them, or any delays. Our results are sent from our encrypted Protonmail server, so please check your spam folder before contacting our Support team for results.
For the antibody test, you have the option of booking a healthcare professional to visit your home and collect a venous blood sample, and they will take care of delivering the sample to the lab.
For PCR tests or self-collected antibody tests, tests are sent using the Royal Mail Special Delivery Next Day Tracked service. If you book a test before 3pm, it will be dispatched to you on the same day for arrival the next working day. All test packages include a pre-stamped envelope to be posted back to our laboratory partners. However, we strongly recommend that you return the test to the laboratory using the Royal Mail Special Delivery Next Day Tracked service, in order to guarantee timely receipt by the lab. Ideally the lab should receive the sample within 24 hours, please keep the sample in your refrigerator during any time delay before posting or collection, and post the sample on the same day. Qured will not be responsible for any delays due to the postal service, or lost tests. If you are self-isolating, please enlist the help of a friend or neighbour to post the test for you.
For PCR tests only, we also offer a priority courier service. If you book before 6pm, the test is delivered to your home or business and collected on the following day, then returned to the laboratory by a courier service. Our courier service is available within M25, and costs an additional £29. You need to select this option when placing the order online.
The courier will deliver and collect between 9:00-19:00. You will be emailed when the test is out for delivery so that you can track it. Once the test is dropped off, the courier will return to collect the test 1-3 hours later. The courier will ring the buzzer/knock when the test is delivered and step away in line with social distancing guidelines. If there is no answer, they will call you on the number provided, so please keep your phone handy and audible.
No. All the test kits are distributed from our fulfilment centre and sent directly to the patient’s home or place of business by courier or postal service.
Orders that are cancelled within 2 hours of placing and before the consultation has taken place will be fully refunded. We cannot refund orders after this.
**This information is for the PCR test only.**
Yes for five years and older. Minors above the age 16 can apply for the test themselves. For age 13 and above, parents can request the test but you will need consent if your child is under 16. For age 5-12 parents can request the test without consent. As for the sample collection required for the test, children age 12 and above may collect the samples themselves if confident to do so, and parents should collect samples for children age 5-12. Please note self-swabbing in children can be challenging and if an adequate sample is not attained, the results may be spurious or they may not be able to process the sample in the lab. Please make sure you and your child (if above 12) have watched the video and read the instructions together. Please assist your child (above 12) at every opportunity to collect the sample.
