Why test for immunity using Chronomics Anti-Spike?

The Chronomics COVID-19 Anti-Spike Immunity Test measures antibodies in your blood. Specifically, it looks for ‘neutralising’ antibodies - ones that stop the virus attaching to your cells.

This kind of immunity is produced by your body in response to both previous infection or vaccination - giving the most accurate picture of your level of protection from COVID-19 before, during and after any infection or jab.

How does it work?

Step 1: Buy and book

Purchase a Chronomics COVID-19 Anti-Spike Immunity Test through us and we’ll make an appointment for you with one of our partner healthcare providers.

Step 2: Take the test

On the day of your appointment, a trained phlebotomist will draw a small sample of your blood – either in-clinic or through at-home services.

Step 3: Register with us

Your sample tube is barcoded and the healthcare provider will register you with Chronomics so you can access our online dashboard when your results are ready.

Step 4: Lab analysis

Your sample is sent to a Chronomics ISO accredited lab to be processed.

Step 5: Get your results

Within 24-36hrs of your sample arriving with us, you’ll receive an email to log into your secure dashboard. Here, you can view your results, download any associated certification you might need, see your testing history and more - all in one place.
