Special instructions

Take this test at least 14 days after you developed symptoms of coronavirus, or 21 days after you were at risk of coronavirus infection. You should take this test before you take any vitamin or mineral supplements. Do not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor.

From the expert

This test measures the level of coronavirus antibodies in your blood (Roche Anti-SARS-CoV-2-S) which you can use to monitor your antibody levels over time to understand your own unique response to the virus or vaccine; we recommend taking a test every 3-4 months.

Your results will tell you if COVID-19 antibodies were detected in your blood, as well as what level those antibodies are. A result below 0.8 U/ml means that the lab did not find antibodies in your sample. A result above 0.8 U/ml means that antibodies were detected, so you likely have had coronavirus (or have been vaccinated). It is possible to get a result below 0.8 U/ml even if you have had a coronavirus infection in the past. This could be because you only experienced mild (or non-existent) symptoms, because your body responded to the virus using different parts of your immune system, or because you took the test too soon after having the virus or vaccination (we recommend waiting 3 weeks).

A vitamin D test is also included. Vitamin D is a fat-soluble vitamin known as the 'sunshine vitamin' because we produce most of what we need through exposure to the sun. Although vitamin D also comes from food, it is difficult to get all your body's requirements from food alone. Vitamin D is important for keeping your bones and teeth healthy, as well as supporting immune function, mental health and muscle function.

Vitamin D deficiency is common in the UK and symptoms include low energy, aches and pains, depression, and getting sick often. 

This test is especially useful for people who may be in a higher risk group for vitamin D deficiency or for people who know that they haven’t managed to be in the sun as often as they would like. If you're over 65, have dark skin or suffer from inflammatory bowel disease or other fat malabsorption conditions you may be more prone to vitamin D deficiency.

Your anonymised data for coronavirus antibodies may be used to help UK public health agencies (including Public Health England) and other organisations understand the spread of coronavirus within the UK population.

This test is only available as a home finger-prick kit. This is because clinic and nurse services are not permitted to collect venous samples for coronavirus antibody tests unless they are covered by UKAS accreditation. As our laboratory is UKAS accredited, we are able to offer this test with a self-collection finger-prick kit.
