Nucleocapsid Antibody

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.

Why do an antibody test for coronavirus?

There are a few reasons why you might want to take an coronavirus antibody test:

  • See if you've had coronavirus
  • See if you've produced an immune response to a vaccine
  • Check if you have some immunity to coronavirus

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.
