Covid antibodies

Roche anti-SARS-CoV-2-S result

Learn more

This test looks for antibodies to the spike protein of SARS-CoV-2, the virus which causes COVID-19. These are the antibodies which the body makes to fight the virus. It measures the quantity of antibodies present, and is reported as a numeric result. The duration and effect of these antibodies in giving immunity to the virus is still being established.

Anti-SARS-CoV-2 S Qualitative

Learn more

The Anti SARS-CoV2 S Qualitative result describes whether coronavirus antibodies were detected or not in your sample. A low numeric result may mean that antibodies were not detected.


Vitamin D

Learn more

Despite its name, vitamin D is actually a hormone that’s produced by your skin when it’s exposed to sunshine. Before your body can use vitamin D produced by sun exposure (known as vitamin D3), it must be converted into another form called 25 hydroxycholecalciferol (25 OH). Vitamin D (25 OH) is the major circulating form of vitamin D, and so your vitamin D (25 OH) level is considered the most accurate indicator of vitamin D supply to your body.

Vitamin D is essential for healthy bones and teeth, as it helps your body absorb calcium. It also plays a role in muscle health, immune function, and mental health.

Low vitamin D symptoms include muscle weakness, mood swings, and fatigue. Many people in the UK have low vitamin D levels, and people with dark skin and people who don’t spend much time outdoors are particularly at risk.

Small amounts of vitamin D can be obtained from food, especially oily fish, eggs, and vitamin-D fortified foods. But if you have a vitamin D deficiency, you’re unlikely to be able to improve your levels by food alone.

What can I learn from this test?

Your results will tell you if COVID-19 antibodies were detected in your blood and 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. After all, 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 three weeks). Your anonymised data 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.

Why is vitamin D included?

Vitamin D deficiency is common in the UK, and symptoms include low energy, aches and pains, depression, and getting sick often. You may be more prone to a vitamin D deficiency if you're over 65, have dark skin, or suffer from inflammatory bowel disease or other fat malabsorption conditions. This test is helpful if you are in a higher-risk group for vitamin D deficiency or haven't been in the sun as often as you would like.

What is the Coronavirus Antibody with Vitamin D Blood Test?

Our test is a laboratory test that measures the level of coronavirus antibodies in your blood (Roche Anti-SARS-CoV-2-S). You can use this test to monitor your antibody levels to record your response to the virus or the vaccine. To monitor your results, we recommend taking a test every three-four months. This test is only available as a home finger-prick kit 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 can offer this test with a self-collection finger-prick kit. Your anonymised data 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.
