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.


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.

Roche anti - SARS - CoV - 2 - S result 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 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 Although called a vitamin, vitamin D is actually a hormone which is activated by sunshine on your skin. Vitamin D is essential for bone strength as it helps your intestines absorb calcium. However, it is thought that vitamin D also plays an important role in immune function, as well as in many chronic diseases and mental health. Many people in the UK have low levels of vitamin D with symptoms including muscle weakness, mood swings and fatigue. People who have dark skin, as well as those who don't spend much time outdoors are particularly at risk of low vitamin D. Small amounts of vitamin D can be obtained from food, especially oily fish, eggs and any food which has been fortified with vitamin D. If you are deficient in vitamin D you are unlikely to be able to improve your levels by food alone.
