This PHE-assessed antibody test looks for both IgG and IgM antibodies against the coronavirus nucleocapsid protein.
The result is reported as "positive" or "negative" - you will not receive a numeric value for your antibody level with this test.
A positive result indicates previous infection with coronavirus.

Antibodies are small molecules produced by the immune system to fight infections. When the body has a new infection, the immune system starts to produce an antibody called IgM which has some activity against the infection. Over time, as the body clears the infection, it creates a better, more targeted antibody called IgG and it stops producing the IgM antibody. Often these IgG antibodies stay in the body for a while and provide protection against future infection with the same bug. Over time though, the body may stop producing even IgG antibodies.
There are a few reasons why you might want to take an coronavirus antibody test:
Up to a third of people who get coronavirus have no symptoms so will not know they've had it. An antibody test can tell you if you've had coronavirus without even realising it.
The coronavirus vaccines are designed to trigger an immune response in much the same way as getting the virus itself. If you've had the vaccine, you can check your bodies response by looking to see if it has produced the "spike protein" antibody.
The latest data shows that most people who've had coronavirus develop antibodies. Furthermore, people with antibodies have significant protection against further infection with the virus. Even if individuals with antibodies get the virus, it's likely they will have a less severe illness. However, it's important to realise that even if you hae antibodies, you are not guaranteed to be immune to the virus.
If you get coronavirus, the body produces different types of antibody which attack different parts of the virus. Two such antibodies are against the "spike" protein and the "nucleocapsid" protein.
If you've been infected with coronavirus you'll actually develop both spike and nucleocapsid antibodies. However, we tend just to test for the nucleocapsid antibodies to say if someone has had the virus or not.
In contrast, if you've been vaccinated against coronavirus, you'll only develop spike antibodies because that's all the vaccine is designed to stimulate. A person who has been vacinated but not had coronavirus would therefor need to take the spike protein antibody test to check their immunity.
Studies show that antibody tests are most accurate when taken three weeks after being vaccinated or being infected with coronavirus. If you test before this, there's a chance your body wont have had time to make sufficient antibodies to detect.
Antibodies persist in the blood for different lengths of time for different people. Data suggests that most people have antibodies for at least 6 months after getting the virus. We don't yet know how long antibodies last after vaccination.
We understand that testing for travel is stressful and complicated. Our in-depth Help Centre will help you understand the process and answer your questions.
We have processed thousands of coronavirus tests and deliver results quickly in the vast majority of cases. However, it's important to be clear about what we can and cannot guarantee.
Self-test kits are dispatched by DPD using a next-day delivery service and you will be provided with tracking information. Delays in delivery are rare but, once dispatched by us, we have no direct control over delivery and cannot accept liability for delays. We highly recommend you order test kits well in advance of when you need to take your sample.
Self-test kits come with a Royal Mail Tracked 24 return envelope to get your sample back to the lab for analysis. The vast majority of samples are delivered to the lab the day after Royal Mail collect from your postbox. However, please bear in mind that last collection times vary and there are no collections (or lab deliveries) on Sundays or public holidays. We have no direct control over samples once they're in the Royal Mail network and cannot accept responsibility for delays in sample return.
The majority of results are sent out within 24 hours of the lab receiving the sample and over 98% of results are back within 48 hours. However, there could be occasions beyond our control where testing volumes rise suddenly and analysis takes longer. We do not own the lab we work with and have no direct control over this. We can't take responsibility for losses (financial or otherwise) caused by the time between the sample being taken and the result being received.
Ocassionally blood samples may clot in the sample tube or the volume of blood may not be sufficient for analysis. This is rare and we will send you another kit to retake your sample.
We pride ourselves on delivering the best customer service experience possible and our customers agree in their reviews on Trustpilot. We will always respond to you quickly and kindly and will always do our best to help you.
We're a group of frontline doctors who strongly believe in responsible medical testing. We want to help people to control of their health through transparent, evidence-based information and access to medical testing.
