Feeling Fatigued After COVID-19? Understand Your Immunity with a Home Antibody Test

Blood tests

Are you still feeling tired long after recovering from COVID-19?

Many people in the UK have reported lingering fatigue, low energy, or brain fog—sometimes weeks or months after a mild COVID-19 infection. This experience, often referred to as long COVID, can make day-to-day life challenging. But how do you know if your immune system has responded to the virus or the vaccine?

What happens inside your body after COVID-19?

After exposure to COVID-19, either through infection or vaccination, your body produces protective proteins called antibodies. The spike antibody is a particular type that targets the virus’s spike protein—crucial for immunity. Low antibody levels may be linked to recurring symptoms or worry about reinfection.

Can you check your COVID immunity at home?

Yes! The COVID-19 Spike Antibody Home Blood Test Kit from Mayfield Clinic allows you to find out your antibody status with a simple finger-prick test. You can collect a small blood sample yourself and send it off in the post, receiving results within as little as one day.

What else can you do for post-COVID symptoms?

Frequently asked questions

Can I use this test if I currently feel unwell with COVID-19 symptoms?

No, the COVID-19 Spike Antibody Home Blood Test Kit is suitable for people who are not currently experiencing symptoms of COVID-19. It checks whether you have developed antibodies after vaccination or infection, not current infection.

How does the COVID-19 spike antibody test differ from a PCR or lateral flow test?

This blood test detects antibodies to the spike protein of the coronavirus, which are produced by your immune system after vaccination or infection. It does not detect the virus itself, so it's not used to diagnose active COVID-19.

Is the finger-prick blood sample painful or difficult to do?

Most people experience mild discomfort with a finger-prick sample. It's quick and easy to use at home, with clear instructions provided in the kit.
